Gene editing of adult human cells, including gene therapy and stem cell therapy, that is used to treat and cure disease. Recent breakthroughs include CAR T-cell therapy, which uses patients’ own immune cells to treat their cancer.
Gene editing of the human embryo or germline that results in genetic changes that are passed down to the next generation. This type of gene editing is the most controversial because changes are inherited and because it could theoretically be used to create “designer babies”. A Chinese scientist announced in 2018 that he had successfully edited twins that were brought to term. International backlash from the announcement has resulted in China and other countries working to clarify regulations on germline gene editing.

Hardly a day goes by without new reports of advances in gene editing. It can be very hard to keep up, even for those following closely. This compilation brings together a list of salient events and media coverage over the last three decades. It is not complete or encyclopedic, but eclectic, focused primarily on CRISPR, and, we hope, illuminating. It will be updated as developments warrant.

5 March, 2020 Joan Conrow Top European science council demands ‘radical’ GMO regulatory reform https://allianceforscience.cornell.edu/blog/2020/03/top-european-science-council-demands-radical-gmo-regulatory-reform/ and https://t.co/HnfNO9YSzH?amp=1

“A top European science council calling is demanding a “radical reform of the legal framework” that regulates genetically modified organisms (GMOs) in the European Union. In a strongly worded commentary, the European Academies Science Advisory Council (EASAC) said the current EU regulations are “no longer fit for purpose” and warned of serious ramifications if the rules are not eased to allow new plant breeding techniques to move forward.”

4 March, 2020 Alexander Avilov Rosneft Joins Russia’s Gene-Editing Tech Program https://www.themoscowtimes.com/2020/03/04/rosneft-joins-russias-gene-editing-tech-program-a69520

“Russia’s oil giant Rosneft and the Russian government will join forces to develop gene-editing technology, according to a government decree published Wednesday. The deal, which President Vladimir Putin ordered in December, aims to accelerate Russia’s $1.6 billion program to create 30 new varieties of genetically modified crops and animals by 2027.”

4 March, 2020 Jeff Akst First Patient Receives In Vivo CRISPR Editing https://www.the-scientist.com/news-opinion/first-patient-receives-in-vivo-crispr-editing-67222

Doctors in Oregon delivered the gene editing machinery behind the retina in hopes of treating an inherited form of blindness, according to the companies that developed the therapy. https://www.the-scientist.com/news-opinion/first-patient-receives-in-vivo-crispr-editing-67222. “Cambridge, Massachusetts–based Editas Medicine and Dublin-based Allergan announced today (March 4) that doctors at the Casey Eye Institute of Oregon Health & Science University in Portland used CRISPR gene editing inside a patient for the first time. They are attempting to treat an inherited form of blindness called Leber congenital amaurosis, the Associated Press reports. The scientists say they will know within a few weeks if the treatment is working and safe, and plan to test it on additional patients if so.”

4 March, 2020 Oliver Xiaoou Dong, et al. Marker-free carotenoid-enriched rice generated through targeted gene insertion using CRISPR-Cas9 https://www.nature.com/articles/s41467-020-14981-y. Also Joan Conrow New study shows CRISPR can be applied to produce biofortified rice https://allianceforscience.cornell.edu/blog/2020/03/new-study-shows-crispr-can-be-applied-to-produce-biofortified-rice/

“A team of California plant scientists has taken a CRISPR-Cas9 approach to develop more nutritious varieties of rice. Their research… demonstrated that CRISPR-Cas9 can be successfully used to biofortify rice with carotenoid, a precursor to the essential nutrient vitamin A. Previous research has demonstrated that biofortification of rice can help prevent blindness, weakened immune systems and other health problems associated with vitamin A deficiency, which is especially prevalent among children in developing nations.”

4 March, 2020 In A 1st, Scientists Use Revolutionary Gene-Editing Tool To Edit Inside A Patient https://www.npr.org/sections/health-shots/2020/03/04/811461486/in-a-1st-scientists-use-revolutionary-gene-editing-tool-to-edit-inside-a-patient

“For the first time, scientists have used the gene-editing technique CRISPR to try to edit a gene while the DNA is still inside a person’s body. The groundbreaking procedure involved injecting the microscopic gene-editing tool into the eye of a patient blinded by a rare genetic disorder, in hopes of enabling the volunteer to see. They hope to know within weeks whether the approach is working and, if so, to know within two or three months how much vision will be restored.”

3 March Krishna Ramanujan Improved CRISPR gene drive solves problems of old tech https://news.cornell.edu/stories/2020/03/improved-crispr-gene-drive-solves-problems-old-tech#.XmJRq506PwQ.twitter

“Gene drives use genetic engineering to create a desired mutation in a few individuals that then spreads via mating throughout a population in fewer than 10 generations… Now, a study… describes a new type of gene drive with the potential to delay resistance. The method could also be applied to a regional population, limiting its spread other populations where it could have undesired effects.”

21 February Ariella Simke You May Find Salt-Tolerant Rice Growing In The Ocean By 2021 https://www.forbes.com/sites/ariellasimke/2020/02/21/you-may-find-salt-tolerant-rice-growing-in-the-ocean-by-2021/?subId1=xid:fr1582662210931gjd#608745534133

“A company started by two 24-year-old scientists wants to produce salt-tolerant rice and floating ocean farms by 2021, with small pilot farms by the end of 2020.”

7 February, 2020 Nature BioTechnology Editors Course Correction https://www.nature.com/articles/s41587-020-0433-3Nature Biotechnology volume 38, page113(2020).

“The US Food and Drug Administration is sticking to its plan to carry out mandatory premarket review of all gene-edited livestock, irrespective of trait risk. It should rethink.”

6 February, 2020 Ed Cara U.S. Trial finds CRISPR-edited cells are safe in cancer patients https://gizmodo.com/u-s-trial-finds-crispr-edited-cells-are-safe-in-cancer-1841495203?utm_medium=sharefromsite&utm_source=gizmodo_twitter.

“researchers say they’ve shown that CRISPR-edited immune cells can be safely given to cancer patients and survive for up to nine months — a finding that may signal CRISPR’s future as part of an emerging cancer treatment known as immunotherapy.”

5 February, 2020 Hannah Kuchler CRISPR pioneer Jennifer Doudna opposes germline-editing moratorium: ‘We’re going to have to figure it out’ https://www.ft.com/content/6d063e48-4359-11ea-abea-0c7a29cd66fe.

“In November 2018, Doudna received an email from Chinese scientist He Jiankui, saying he planned to announce the birth of Crispr-edited twins at an upcoming conference in Hong Kong. The children were engineered without the knowledge of the international scientific community, whose leading members — among them Doudna — had been pressing for a moratorium on germline editing. Doudna declined to sign another call for a moratorium after the revelation of the Chinese babies, saying that there needs instead to be appropriate regulation of gene editing. In A Crack in Creation, a book she co-authored in 2017, she wondered whether we would ever have the intellectual and moral capacity to make decisions about germline editing. I ask if she still feels that way. “I would say my feeling today is that, like it or not, we’re going to have to figure it out,” she says.”

4 February, 2020 Sara Reardon Step aside CRISPR, RNA editing is taking off — Making changes to the molecular messengers that create proteins might offer flexible therapies for cancer, pain or high cholesterol, in addition to genetic disorders. https://www.nature.com/articles/d41586-020-00272-5.

“Thorsten Stafforst found his big break at the worst possible time. In 2012, his team at the University of Tübingen… discovered that by linking enzymes to engineered strands of RNA, they could change the sequences of messenger RNA molecules in cells. In essence, they could rewrite the genome’s instructions en route to making proteins. The process could theoretically serve to treat numerous diseases… But Stafforst had a lot of trouble getting the discovery published — it was simply not interesting any more. His finding was overshadowed by the discovery a few months earlier that the DNA-editing tool CRISPR–Cas9 could be used to permanently alter the genome.”

4 February, 2020 National Agricultural Technology Institute Field trials of non-browning CRISPR-edited potatoes begin in Argentina https://geneticliteracyproject.org/2020/02/04/field-trials-of-non-browning-crispr-edited-potatoes-begin-in-argentina/.

“In a study published recently in the Frontiers in Plant Science magazine, scientists from Argentina and Sweden reported they have edited a polyphenol oxidase gene in potatoes ( Solanum tubersoum L.). After successfully editing the gene, they obtained tubers free of enzymatic browning.”

4 February, 2020 Arthur Neslen, Eddy Wax, Louise Guillot Leaked proposals suggest EU may assess CRISPR gene editing to ‘improve sustainability’ of food production https://geneticliteracyproject.org/2020/02/04/leaked-proposals-suggest-eu-may-assess-crispr-gene-editing-to-improve-sustainability-of-food-production/.

“More leaked drafts of the Farm to Fork (F2F) strategy reveal how the [European] Commission’s plan to make EU food production greener and healthier is taking shape. There are far fewer policy proposals in these two draft action plans, both dated January 13, suggesting the plan has undergone some serious redrafting by Commission wonks since an earlier, more wide-ranging document, dated January 6, floated 95 policies.”

31 January, 2020 Peter Beetham How Gene Editing is Reshaping Agriculture https://seedworld.com/how-gene-editing-is-reshaping-agriculture/.

“With gene editing comes a new model of how crops are improved and produced, who produces the plants, and how they will be introduced to farmers and importantly how plant breeding can quickly respond to change including arming crops with traits to combat our changing climate. The changes coming to agriculture will be as profound as the original marriage of agriculture and genetics, but this revolution represents a return to the way plants adapt in nature. “

31 January, 2020 David Warmflash The real sustainability revolution in farming rests with CRISPR and other New Breeding Techniques. Why are organic farmers blocked from using them? https://geneticliteracyproject.org/2020/01/31/the-real-sustainability-revolution-in-farming-rests-with-crispr-and-other-new-breeding-techniques-why-are-organic-farmers-blocked-from-using-them/.

“[Gene edited] …crops, however, cannot be sold as organic. That status is defined by organic authorities and in most cases is not related to how things are grown, nor to whether the crop is produced sustainably. Indeed, in some cases, crops developed through NBTs can be grown with less potentially harmful inputs than those granted organic status. This disconnect between sustainability and organic certification is likely to persist in the foreseeable future because the standards that are used to designate which farm products receive an organic seal are based on, or at least influenced strongly, by ideological forces. The main such force in this case, promoted by organic authorities, is a belief that classic organic techniques are more environmentally sensitive than newer techniques, which they claim are untested and potentially dangerous.

30 January 2020 Fyodor D. Urnov Prime Time for Genome Editing? N Engl J Med 2020; 382:481–484 DOI: 10.1056/NEJMcibr1914271 https://www.nejm.org/doi/full/10.1056/NEJMcibr1914271.

“Protein engineering has yielded a new, potent tool — in the form of a chimeric enzyme — for correcting genetic mutations. Proof of principle that this enzyme can correct different types of mutation, and even combinations of mutations, has been obtained in different types of mammalian cells…”

30 January, 2020 Arizona State University ASU scientists boost gene-editing tools to new heights in human stem cells — Proof-of-concept shows genes implicated in Alzheimer’s disease can be accurately edited with 90% efficiency in human stem cells. https://phys.org/news/2020-01-scientists-boost-gene-editing-tools-heights.html.

“… Brafman, using a new update to the CRISPR base editing technology… has vastly outperformed previous efforts by making highly accurate, single-DNA base editing with an efficiency of up to 90% of human stem cells. The results were published in the journal Stem Cell Reports

“Scientists from Hainan University and Huazhong Agricultural University developed a simple and efficient cloning method for CRISPR-Cas9-mediated genome editing in rice. The results are published in PeerJ Life and Environment.”

29 January 2020 ISAAA Study Reveals Experts’ and Public’s Attitude Towards Gene-edited Crops http://www.isaaa.org/kc/cropbiotechupdate/article/default.asp?ID=17938#.XjF6DU6qXGk.twitter.

“A team of Japanese researchers… surveyed perceptions of Japanese experts and the public of the benefits, risks, and value of using gene editing for developing crops compared to other emerging or conventional breeding techniques in Japan… [finding] participants who had expert knowledge of molecular biology perceived emerging technologies to offer the lowest risk and highest benefits or value for food application, while lay public showed the highest risk and lowest benefit.”

23 January 2020 Seth Truscott Disabling viruses with CRISPR scissors https://news.wsu.edu/2020/01/23/disabling-viruses-crispr-scissors/.

“Viruses cause billions of dollars in losses for many food, feed, and fiber crops, including staples like wheat, rice, potatoes, cassava, beans, and plantains. In a scientific first, Washington State University researchers delivered a one-two punch to knock out these viruses, using precise, targeted editing of viral genes. Popularly known as CRISPR-Cas9, this genome editing approach can delete and replace individual bases in DNA.”

22 January, 2020 Mark Terry Newly ID’ed T-Cells Have Potential to Become Universal Cancer Therapy https://www.biospace.com/article/researchers-id-immune-cell-that-can-attack-almost-all-cancer-cells/ & https://www.nature.com/articles/s41590-019-0578-8.epdf?referrer_access_token=snY5ZB-EgcG5gMxu6h5BxdRgN0jAjWel9jnR3ZoTv0NjOoBZR7tEtwlsa1xeSU1tSn9OqKp9tJ7vTk8p7vCmAU4NZd5dS3BIALSEUtLFcpomMuKDUbEnW8GutXD_HuOev_ekvAEfzAa2kC03oyp2SuhBvB2N5K9feGAqhcKqIKgZC2OWk5VF1AgHIU4VXmKYeN0eWdmTgIw5Jb227ILGMg%3D%3D&tracking_referrer=www.bbc.com

“The researchers essentially identified a new T-cell and its receptor that appears able to search out and kill a broad range of cancer cells, including lung, skin, blood, colon, breast, bone, prostate, ovarian, kidney and cervical cancer cells. It left noncancerous cells alone. “There’s a chance here to treat every patient,” Andrew Sewell, professor, Division of Infection and Immunity, School of Medicine at Cardiff, told the BBC. “Previously nobody believed this could be possible. It raises the prospect of a ‘one-size-fits-all’ cancer treatment, a single type of T-cell that could be capable of destroying many different types of cancers across the population.” The T-cell they identified interacts with a cell surface molecule, MR1. MR1 is believed to flag the abnormal metabolism inside a cancer cell.

22 January 2020 Flora Southey Vertical farms of the future require genetically edited plants, says scientist. https://www.foodnavigator.com/Article/2020/01/22/Vertical-farms-of-the-future-require-genetically-edited-plants-says-scientist

“There is an innovation gap in urban agriculture, suggests Aberystwyth University Professor Huw Jones, whereby we have ‘huge innovation’ in vertical farming, yet still use ‘old seeds’ and ‘old plant architecture’.”

20 January 2020 Michael Le Page CRISPR-edited chickens made resistant to a common virus https://www.newscientist.com/article/2230617-crispr-edited-chickens-made-resistant-to-a-common-virus/.

“CRISPR genome editing has been used to make chickens resistant to a common virus. The approach could boost egg and meat production worldwide while improving welfare. The altered chickens showed no signs of disease even when exposed to high doses of the avian leukosis virus (ALV). The virus is a problem for poultry farmers around the world, says Jiri Hejnar at the Czech Academy of Sciences.”

17 January 2020 Elie Dolgin The kill-switch for CRISPR that could make gene-editing safer — How anti-CRISPR proteins and other molecules could bolster biosecurity and improve medical treatments https://www.nature.com/articles/d41586-020-00053-0?utm_source=twt_nnc&utm_medium=social&utm_campaign=naturenews&sf228283173=1.

“[researchers] …stumbled onto tools now known as anti-CRISPRs. These proteins serve as the rocks to CRISPR’s molecular scissors… more than 50 anti-CRISPR proteins have now been characterized, each with its own means of blocking the cut-and-paste action of CRISPR systems. The expansive roster opens up many questions about the archaic arms race between bacteria and the phages that prey on them. But it also provides scientists with a toolkit for keeping gene editing in check. Some are using these proteins as switches to more finely control the activity of CRISPR systems in gene-editing applications for biotechnology or medicine. Others are testing whether they, or other CRISPR-stopping molecules, could serve as biosecurity counter-measures of last resort, capable of reining in some genome-edited bioweapon or out-of-control gene drive.”

13 January 2020 EuroSeeds 26 business organizations support a Commission study on “novel genomic techniques” and express their hope for more enabling regulations https://www.euroseeds.eu/news/update-26-european-business-organisations-ask-the-eu-to-submit-a-study-on-the-status-of-novel-genomic-techniques/.

On 9 January, 26 European business organisations jointly signed a letter calling upon the European Commission and Member States to re-emphasize that products obtained by novel genomic techniques should not be subject to Directive 2001/18 requirements and related regulations if they could also have been obtained through conventional methods or result from spontaneous processes in nature. The organizations support the Council Decision (EU) 2019/1904 requesting the Commission to submit a study on the status of novel genomic techniques and welcome the potential for a Commission proposal, which they hope will deliver more enabling rules for products resulting from the latest breeding methods, while keeping high standards of EU food production.”

9 January Global Scientists Object: EC study on the status of novel genomic techniques — Scientists open letter challenge European Commission to develop scientifically defensible regulations for gene edited products https://www.euroseeds.eu/app/uploads/2020/01/Draft-value-chain-letter-to-new-Comm-18-12-2019.pdf

“The undersigned value chain partners strongly support Council Decision (EU) 2019/1904 requesting the Commission to submit a study on the status of novel genomic techniques1 and welcome the potential for a Commission proposal, which we hope will deliver more enabling rules for products resulting from the latest breeding methods, while keeping high standards of EU food production. In this context we would like to re-emphasize our position that products should not be subject to Directive 2001/18 requirements and related regulations if they could also have been obtained through conventional methods or result from spontaneous processes in nature. This differentiated regulatory approach, which looks at both, the process and the product, thus taking into account the benefits of these novel genomic techniques and the resulting products is taken up in a growing number of countries around the world.”

7 January 2020 Jenna Gallegos CRISPR: Overcoming its obstacles in plant research https://allianceforscience.cornell.edu/blog/2020/01/crispr-overcoming-its-obstacles-in-plant-research/.

“CRISPR is an extremely powerful gene editing tool that has already made huge waves in plant research. We can potentially use CRISPR to make hardier crops, engineer produce in ways that directly benefit consumers and address climate change. But while CRISPR is often described as “cut and paste” for genes, the actual process is not that simple. Scientists still face several obstacles associated with using CRISPR in plant research, including regulatory hurdles.”

30 December Zaobao.com He Jiankui illegally edits human embryo genes, sentenced to three years in prison https://www.zaobao.com.sg/realtime/china/story20191230-1017060.

“The “gene-edited baby” case was publicly sentenced in the first instance of the Nanshan District People’s Court in Shenzhen today. The three defendants, He Jiankui, Zhang Renli, and Qin Jinzhou, jointly executed the human embryo gene editing and reproductive medical activities for reproductive purposes, which constituted the crime of illegal medical practice, and were each held criminally responsible according to law… He Jiankui was sentenced to three years’ imprisonment and a fine of 3 million yuan (RMB, the same below, about S $ 600,000)… and barred [him] from engaging in human assisted reproductive technology services for life.”

23 December Cold Spring Harbor Laboratory A new tomato ideal for urban gardens and even outer space https://phys.org/news/2019-12-tomato-ideal-urban-gardens-outer.html.

“Farmers could soon be growing tomatoes bunched like grapes in a storage unit, on the roof of a skyscraper, or even in space. That’s if a clutch of new gene-edited crops prove as fruitful as the first batch.”

23 December Siobhán Dunphy Can gene-edited pigs remedy the global shortage of human organs? https://www.europeanscientist.com/en/public-health/can-gene-edited-pigs-remedy-the-global-shortage-of-human-organs/.

“Scientists have used CRISPR technology to develop a new generation of gene-edited pigs that may one day provide much-needed donor organs for people. The genetically engineered animals are described in a new paper published on 19 December in BioRxiv (1). So-called xenotransplantation — the use of non-human organs for transplant, in this case, pigs — could provide a viable alternative to human donor shortages, thanks to genetic engineering. Pigs are widely consumed around the world, so breeding them for replacement body parts presents much less of a moral dilemma than other animals with organs similar to humans, like say monkeys. Pigs also reach adulthood in just six short months and the anatomy of pig organs are quite close to those of human organs.

“The cookie’s many names — biscuits, rusks, wafers, galletas — show that our love for these sweet treats transcends geographic bounds. However, a changing climate and spreading pests and diseases pose a risk to cookie jars all over the world. Bakers and cookie lovers can rest easy, though, because there’s a solution within reach: gene editing. By making small changes to crops’ DNA, scientists can improve the key ingredients in our favorite cookies to withstand more risks than ever before. These changes can help crops protect themselves against rising temperatures, as well as pests and diseases. Here are five cookies that gene editing could improve…”

16 December University of Minnesota Research Brief: New methods promise to speed up development of new plant varieties https://twin-cities.umn.edu/news-events/research-brief-new-methods-promise-speed-development-new-plant-varieties.

“A University of Minnesota research team recently developed new methods that will make it significantly faster to produce gene-edited plants. They hope to alleviate a long-standing bottleneck in gene editing and, in the process, make it easier and faster to develop and test new crop varieties with two new approaches described in a paper recently published in Nature Biotechnology… The new methods will: drastically reduce the time needed to edit plant genes from as long as nine months to as short as a few weeks; work in more plant species than was possible using tissue culture, which is limited to specific species and varieties; allow researchers to produce genetically edited plants without the need of a sterile lab, making it a viable approach for small labs and companies to utilize. To eliminate the arduous work that goes into gene-editing through tissue culture, co-first authors Ryan Nasti and Michael Maher developed new methods that leverage important plant growth regulators responsible for plant development.”

13 December Xingming Hu, et al. Using CRISPR-Cas9 to generate semi-dwarf rice lines in elite landraces https://www.nature.com/articles/s41598-019-55757-9.

“…Expanding the genetic diversity among Chinese rice varieties and cultivating high-yielding and high-quality varieties with resistance to different biotic and abiotic stresses is critical. Here, we used the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein9(Cas9) genome editing system to edit Semi-Dwarf1 (SD1) in the elite landraces Kasalath and TeTePu (TTP), which contain many desired agronomic traits such as tolerance to low phosphorous and broad-spectrum resistance to several diseases and insects. Mutations of SD1 confer shorter plant height for better resistance to lodging. Field trials demonstrated that the yield of the new Kasalath and TTP mutant lines was better than that of the wild type under modern cultivation and that the lines maintained the same desirable agronomic characteristics as their wild-type progenitors. Our results showed that breeding using available landraces in combination with genomic data of different landraces and gene-editing techniques is an effective way to relieve genetic erosion in modern rice varieties.”

11 December Charlie Arnot Gene Editing: It’s an Evolution, not a Revolution https://www.fb.org/viewpoints/gene-editing-its-an-evolution-not-a-revolution.

“The Coalition for Responsible Gene Editing in Agriculture… analyzed consumer research about communicating about biotechnology and they discovered that some methods of communicating are more effective than others. One discovery was that talking about the evolution of gene editing technology — instead of describing it as a revolution — helped people to understand it better… However, talking about how science can “revolutionize” food production does not resonate with consumers. The public is more supportive when gene editing is described within the context of plant and animal genetic improvement, which has a legacy of safe, responsible use spanning several generations. Rather than being a revolutionary technique, consumers are more comfortable when gene editing is approached as an evolution of the next iteration of improvement. It’s also helpful to identify the way gene editing can benefit consumers directly while aligning with public desires. The top three gene editing benefits that consumers care about most are the environment, disease resistance and animal wellbeing.”

11 December Maria Chaplia Viewpoint: With Conservative sweep of the ‘Brexit election’, Boris Johnson poised to steer the UK out of ‘outdated’ EU GMO, CRISPR regulations https://geneticliteracyproject.org/2019/12/11/viewpoint-with-conservative-sweep-of-the-brexit-election-boris-johnson-poised-to-steer-the-uk-out-of-outdated-eu-gmo-crispr-regulations/.

In the wake of the Conservative Party’s crushing victory in the election in the United Kingdom, Prime Minister Boris Johnson is poised to navigate Britain’s exit from the European Union. Once out of the EU, the UK could regain full control over its laws and regulations. And that might open the door to a reversal on what scientists consider its backward-looking policies on GMOs and CRISPR gene editing in agriculture.”

5 December Natasha Foote EU study to clarify gene editing court ruling further muddies waters https://www.euractiv.com/section/agriculture-food/news/eu-study-to-clarify-gene-editing-court-ruling-further-muddies-waters/?utm_term=Autofeed&utm_medium=social&utm_source=Twitter#Echobox=1575559196.

“After the controversial European Court of Justice (ECJ) ruling in 2018 that organisms obtained by new plant breeding techniques (NBTs) should, in principle, fall under the GMO Directive, the Council of the EU has requested a study from the Commission to clarify the situation. But what this means in practice remains unclear, stakeholders have told EURACTIV. Speaking at a recent event on NBTs, Jari Leppä, Finnish agriculture minister and current president of the EU agri-fish council, confirmed the Council had requested a study on the “options to update the existing legislation”. He added that “if necessary, the Commission must be prepared to submit a proposal to amend the GMO directive”. But the exact purpose and aim of the request are not immediately clear.”

“In July 2018, the European Court of Justice ruled that the legal regulations for genetically modified organisms (GMOs) apply to all organisms which have been altered using genome editing methods such as CRISPR-Cas. This makes it difficult to study, develop and cultivate improved crops which are urgently needed for productive, climate-adapted and more sustainable agriculture. The National Academy of Sciences Leopoldina, the Union of the German Academies of Sciences and Humanities, and the German Research Foundation (DFG)… point out that this blanket legal classification of GMOs does not take into account what type of genetic modification is present in a given organism. In the eyes of the science academies and the DFG, this primarily process-based regulatory approach has no rational justification. They have offered recommendations on how European genetic engineering legislation can be amended as a short-term solution and completely renewed in the long term.”

“The EU is leading the science-based fight against climate change and will also lead on science-based plant innovation, writes former EU Health Commissioner Vytenis Andriukaitis… Plant breeding has been practiced by humans since almost the beginning of our civilisation. We have been experimenting with different species and plant varieties, with some impressive results. We bred corn from teosinte and strawberries from wild berries. Natural selection and artificial methods have been used to create desired mutations and get an improved breed. Now, we found a faster way to breed, mix and produce better varieties — via gene engineering. This could sound like a success story, right? Alas, a tide of suspicion and fear pushed these innovations outside the EU.”

“ Currently there is no commercially available vaccine against African swine fever. Outbreaks of this disease are devastating the swine industry from Central Europe to East Asia, and they are being caused by circulating strains of African swine fever virus derived from the Georgia2007 isolate. Here we report the discovery of a previously uncharacterized virus gene, which when deleted completely attenuates the Georgia isolate. Importantly, animals infected with this genetically modified virus were protected from developing ASF after challenge with the virulent parental virus.”

“This past July saw a big leap forward for clinical application of CRISPR-based genome editing, with the launch of the Brilliance trial by Allergan and Editas Medicine. Previous clinical forays into genome editing have focused on manipulating isolated human cells in the laboratory, which are then transplanted back into patients. In contrast, Brilliance will be the first in vivo test of this technology in humans, with patients receiving direct injections of viral particles laden with genes encoding the CRISPR-Cas9 machinery to correct a retinal gene defect.”

1 December Ruth Williams DNA-responsive polymer gels used for releasing drugs, encapsulating cells, and much more now have greater adaptability thanks to the Cas12a nuclease https://www.the-scientist.com/modus-operandi/crispr-based-tool-expands-dna-hydrogel-versatility-66751?utm_content=110496346&utm_medium=social&utm_source=twitter&hss_channel=tw-18198832.

“…the team created DNA-containing hydrogels that, in response to a dsDNA cue provided by the researchers, could either release DNA-bound compounds or fully degrade. Such degradation could be used for applications such as liberating encapsulated contents like cells or nanoparticles, initiating flow of a buffer through a microfluidic device, or opening an electrical circuit. These last two examples could potentially be used in diagnostic devices, says Collins, with a change in buffer flow or electrical output signaling the presence of a DNA sequence of interest in a patient sample. “They showed some really novel applications of responsive hydrogels,” says Rebecca Schulman, a chemical and biomolecular engineer at Johns Hopkins University… “Their approach is totally customizable . . . [and] is really cleverly designed,” adds bio-engineer Dan Luo of Cornell University… “It’s a real integration of molecular biology and materials science.” (Science, 365:780–85, 2019).

“Highlights: Genome edited crops pose marginal risk to the economy, human health and the environment; Existing national regulations work to discourage genome editing in many countries; Advocacy groups tend to discourage the use of new gene technologies in agriculture based on speculative risks; Risks associated with genome editing are driven more by socio-political factors than by scientific principles; Majority of experts are for inclusion of social-economic considerations in the regulation of biotechnology.”

21 November Ag News Gene editing delivers 15–16% protein sorghum http://news.agropages.com/News/Detail-32959.htm

“Researchers have achieved a major breakthrough in sorghum, elevating the protein of the globally important cereal crop from 9–10 per cent to a staggering 15–16pc. The breakthrough was revealed by Professor Ian Godwin (pictured) at the TropAg 2019 conference in Brisbane, following research carried out by the Queensland Alliance for Agriculture and Food Innovation. The development has the poultry and pigs industries particularly excited, as well as beef feedlots. The increase in protein is expected to result in about a 50c/head reduction in the cost of producing a 2kg meat bird. The breakthrough is also expected to generate big interest in the 46 Sub-Saharan African countries, where an estimated 500 million people rely on sorghum as a food source.”

20 November Human germline editing needs one message — Science academies and the World Health Organization must act in unison. https://www.nature.com/articles/d41586-019-03525-0.

“In 2018, the World Health Organization (WHO) set up an independent expert panel to advise on the oversight and governance of human genome editing. A separate international commission on the clinical use of human germline genome editing gathered for its second meeting in London last week. This commission was established by the US National Academy of Science, the US National Academy of Medicine and Britain’s Royal Society, to recommend standards and criteria for germline genome editing. Both will report next year, and the commission’s report will feed into the WHO process. But the WHO panel has already recommended setting up a public registry for genome-editing experiments. It has also made an interim recommendation that “it would be irresponsible at this time for anyone to proceed with clinical applications of human germline genome editing”, which has been accepted by the agency’s leadership. The international commission has yet to say what it thinks, but it would make little sense for it to disagree. It isn’t entirely clear why separate initiatives are needed, and it is unfortunate that representatives of people with disabilities are not part of the decision-making process. However, it isn’t too late to rectify these issues, and the two initiatives must, in the end, converge.”

15 November Jennifer Doudna CRISPR’s unwanted anniversary https://science.sciencemag.org/content/366/6467/777.

“There are key moments in the history of every disruptive technology that can make or break its public perception and acceptance. For CRISPR-based genome editing, such a moment occurred 1 year ago — an unsettling push into an era that will test how society decides to use this revolutionary technology. In November 2018, at the Second International Summit on Human Genome Editing in Hong Kong, scientist He Jiankui announced that he had broken the basic medical mantra of “do no harm” by using CRISPR-Cas9 to edit the genomes of two human embryos in the hope of protecting the twin girls from HIV. His risky and medically unnecessary work stunned the world and defied prior calls by my colleagues and me, and by the U.S. National Academies of Sciences and of Medicine, for an effective moratorium on human germline editing. It was a shocking reminder of the scientific and ethical challenges raised by this powerful technology. Once the details of He’s work were revealed, it became clear that although human embryo editing is relatively easy to achieve, it is difficult to do well and with responsibility for lifelong health outcomes.”

14 November Sean Pratt CropLife [Canada] calls for clarity on gene-editing regulations https://www.producer.com/2019/11/croplife-calls-for-clarity-on-gene-editing-regulations/.

Canada is falling behind other jurisdictions in providing clarity on how it will regulate new crop varieties developed through gene editing techniques such as CRISPR, says CropLife Canada. Japan’s consumer affairs agency recently decided it will not require special labelling for products created through the new breeding technique because it does not require the introduction of foreign DNA. Japan joins a growing list of countries such as the United States, Australia, Argentina and Chile that do not plan to give any extra scrutiny to new traits resulting from gene editing.”

“A paper recently published in Nature from David Liu and co-workers discloses a ‘prime’ gene-editing system many years in the making. The prime system may have fewer undesirable off-target effects than editing with CRISPR–Cas9… In principle, the system, comprising a catalytically impaired Cas9 enzyme and an engineered reverse transcriptase, may be able to address ~89% of the human genetic variants known to be pathogenic. Already, it has been snapped up as the key founding intellectual property for Cambridge, Massachusetts-based startup Prime Medicine… Prime editing is still a nascent, albeit highly promising, technology. Demonstrating its feasibility in a wide range of cells and tissues will be key to its future development.”

“Desperate to find new medicines against pathogenic microorganisms, scientists are turning to Crispr, the gene-editing tool. Crispr has typically been considered for macroscopic tasks: altering mosquitoes so they can’t spread malaria, editing tomatoes so they are more flavorful and curing certain genetic diseases in humans. Now researchers are harnessing Crispr to turn a bacterium’s machinery against itself, or against viruses that infect human cells. “Crispr is the next step in antimicrobial therapy,” said David Edgell, a biologist at the Western University in London, Ontario, and the lead author of a study published earlier this month in Nature Communications.”

“Most genetic variants that contribute to disease1 are challenging to correct efficiently and without excess byproducts. Here we describe prime editing, a versatile and precise genome editing method that directly writes new genetic information into a specified DNA site… We performed more than 175 edits in human cells, including targeted insertions, deletions, and all 12 types of point mutation, without requiring double-strand breaks or donor DNA templates. We used prime editing in human cells to correct, efficiently and with few byproducts, the primary genetic causes of sickle cell disease (requiring a transversion in HBB) and Tay–Sachs disease (requiring a deletion in HEXA); to install a protective transversion in PRNP; and to insert various tags and epitopes precisely into target loci.”

21 October: Jon Cohen New ‘prime’ genome editor could surpass CRISPR https://www.sciencemag.org/news/2019/10/new-prime-genome-editor-could-surpass-crispr.

“CRISPR, an extraordinarily powerful genome-editing tool invented in 2012, can still be clumsy. It sometimes changes genes it shouldn’t, and it edits by hacking through both strands of DNA’s double helix, leaving the cell to clean up the mess — shortcomings that limit its use in basic research and agriculture and pose safety risks in medicine. But a new entrant in the race to refine CRISPR promises to steer around some of its biggest faults. “It’s a huge step in the right direction,” chemist George Church, a CRISPR pioneer at Harvard University, says about the work, which appears online today in Nature. This newfangled CRISPR, dubbed “prime editing,” could make it possible to insert or delete specific sequences at genome targets with less collateral damage. “Prime editors offer more targeting flexibility and greater editing precision,” says David Liu, a chemist at the Broad Institute in Cambridge, Massachusetts, whose lab led the new study and earlier invented a popular CRISPR refinement called base editing.”

“HOUSTON, Texas — Scientists are finding new ways to improve the use of the CRISPR enzyme Cas9 and reduce the chances of off-target mutations in laboratory mice, according to new results from a research collaboration including Lauryl Nutter, PhD, Senior Director, Science and Technology Development at The Centre for Phenogenomics at The Hospital for Sick Children (SickKids) in Toronto… In 31 of the Cas9-treated mouse lines, the researchers found zero off-target mutations, and in the remaining 20 lines, they found an average of 2.3 off-target mutations. In comparison, among both the treated and untreated mouse lines, they found an average of 3,500 naturally occurring, unique mutations in each animal. “Surprisingly, these results show that the number of naturally-occurring mutations far exceeded those introduced by Cas9,” Dr. Nutter said. “They also show that when guide RNAs are properly designed, off-target mutagenesis is quite rare.””

“Humankind is on the verge of a genetic revolution that holds great promise and potential. It will change the ways food is grown, medicine is produced, animals are altered and will give rise to new ways of producing plastics, biofuels and chemicals… Gene editing of humans and plants — a revolutionary technique developed just a few years ago that makes genetic tinkering dramatically easier, safer and less expensive — has begun to accelerate this revolution. University of California-Berkeley biochemist Jennifer Doudna, one of the co-inventors of the CRISPR technique: ‘Within the next few years, this new biotechnology will give us higher-yielding crops, healthier livestock, and more nutritious foods. Within a few decades, we might well have genetically engineered pigs that can serve as human organ donors…we are on the cusp of a new era in the history of life on earth — an age in which humans exercise an unprecedented level of control over the genetic composition of the species that co-inhabit our planet. It won’t be long before CRISPR allows us to bend nature to our will in the way that humans have dreamed of since prehistory.’”

“As an organization of basic research, the Max Planck Society bears a special responsibility for the use of new scientific techniques for the benefit of humans and the environment. The Ethics Council of the Max Planck Society has therefore prepared a discussion paper on so-called genome editing, which highlights the potentials and risks of this method. In the paper, the Ethics Council concludes that the various uses of the technology in plant breeding, medicine or pest control bring their own ethical issues. These must be answered individually. For example, the Max Planck Society is aware of the implications of inheritable artificial mutations, such as those caused by genome editing of germ line cells. For the time being, therefore, it will not conduct any research on the genetic modification of germline cells. Instead, she wants to participate in the discussion based on the latest scientific findings and the development of international standards.”

“Monarch butterflies eat only milkweed, a poisonous plant that should kill them. The butterflies thrive on it, even storing milkweed toxins in their bodies as a defense against hungry birds. For decades, scientists have marveled at this adaptation. On Thursday, a team of researchers announced they had pinpointed the key evolutionary steps that led to it. Only three genetic mutations were necessary to turn the butterflies from vulnerable to resistant, the researchers reported in the journal Nature. They were able to introduce these mutations into fruit flies, and suddenly they were able to eat milkweed, too… Noah Whiteman, an evolutionary biologist at the University of California, Berkeley, …and his colleagues figured out how to use Crispr, the gene-editing technology, to introduce the mutations into fruit flies.”

“In 2012 American biochemist Jennifer Doudna and her collaborator, Emmanuelle Charpentier, proposed that CRISPR — a group of genes and molecules used by bacteria to recognise and destroy viral DNA — could be re-purposed as a powerfully simple and programmable gene-editing tool. Their work led to an explosion of interest in CRISPR and exciting new applications of gene-editing across all areas of biology. With its unprecedented efficiency and ease of use, CRISPR has not only supplanted all previous genetic engineering technologies, but has revolutionised what is possible in life science — at the same time raising profound questions about what society should and should not do with such powerful technology.”

“CRISPR is a simple and versatile tool for genome engineering, but its utility is dependent on its ability to infiltrate cells. Options for CRISPR delivery include plasmid transfection, RNP electroporation, and viral transduction; but these methods aren’t stealthy enough to gain access to some cells and tissues, such as human induced pluripotent stem cells (hiPSCs). Nanoblades, a new CRISPR delivery method developed by the Ricci Lab, adds a covert tool to the CRISPR tool box. Nanoblades are engineered murine leukemia virus (MLV)-like particles loaded with Cas9-gRNA ribonucleoproteins (RNPs). According to the authors, they named their tool Nanoblades because they think of these particles as tiny DNA cutting ninjas that deliver CRISPR to multiple types of targets: primary cells, embryos, and animals. Nanoblades can also carry different types of CRISPR cargo including RNPs for indel formation via NHEJprecise modification with Homology Directed Repair (HDR), CRISPR activation or repressiontransgenic mouse line creation, and in vivo gene editing of mice, with the potential to be used for other types of CRISPR applications. “

“As crop biotechnology continues to advance, conventional farmers are gaining access to new tools that drastically cut pesticide use. This downward trend in chemical dependency goes back to the introduction of genetically modified (GM) crops in the 1990s, and will only accelerate as more gene-edited crops and animals reach the market in the near future. The organic industry, meanwhile, continues to sit out this sustainability revolution for ideological and economic reasons, which ultimately encourages pesticide use.”

“The race to engineer the next-generation banana is on. The Colombian government confirmed last month that a banana-killing fungus has invaded the Americas — the source of much of the world’s banana supply. The invasion has given new urgency to efforts to create fruit that can withstand the scourge. Scientists are using a mix of approaches to save the banana. A team in Australia has inserted a gene from wild bananas into the top commercial variety — known as the Cavendish — and are currently testing these modified bananas in field trials. Researchers are also turning to the powerful, precise gene-editing tool CRISPR to boost the Cavendish’s resilience against the fungus, known as Fusarium wilt tropical race 4 (TR4).”

“Now, researchers report they’ve adapted CRISPR and combined it with other tools to cut and splice large genome fragments with ease. “This new paper is incredibly exciting and a huge step forward for synthetic biology” …The technique will enable synthetic biologists to take on “grand challenges,” she says, such as “writing of information to DNA and storing it in a bacterial genome or creating new hybrid bacterial species that can carry out novel [metabolic reactions] for biochemistry or materials production.”

“Genetically engineered crops have been grown for more than 20 years, resulting in widespread albeit variable benefits for farmers and consumers. We review current, likely, and potential genetic engineering (GE) applications for the development of disease-resistant crop cultivars. Gene editing, gene drives, and synthetic biology offer novel opportunities to control viral, bacterial, and fungal pathogens, parasitic weeds, and insect vectors of plant pathogens. We conclude that there will be no shortage of GE applications to tackle disease resistance and other farmer and consumer priorities for agricultural crops. Beyond reviewing scientific prospects for genetically engineered crops, we address the social institutional forces that are commonly overlooked by biological scientists. Intellectual property regimes, technology regulatory frameworks, the balance of funding between public- and private-sector research, and advocacy by concerned civil society groups interact to define who uses which GE technologies, on which crops, and for the benefit of whom. Ensuring equitable access to the benefits of genetically engineered crops requires affirmative policies, targeted investments, and excellent science.”

“Forest certification bodies were established to provide consumers with confidence that they are purchasing sustainably sourced wood products… However, certification bodies have consistently excluded all genetically engineered or gene-edited (GE) trees from certification, including from field research on certified lands that is essential for understanding local benefits and impacts. We, leading forest biotechnology scientists from around the world, with the support of more than 1000 globally diverse signatories to a recent detailed petition, call for all forest certification systems to promptly examine and modify these policies.”

22 August: Antonio Regalado The next trick for CRISPR is gene-editing pain away — A family of street performers could walk on coals. Here’s how the secret of why they felt no pain could benefit others https://www.technologyreview.com/s/614210/the-next-trick-for-crispr-is-gene-editing-pain-away/.

“The street performer was only 10 years old. He put knives through his arms and walked on hot embers. By 14 he was dead. Someone dared him to jump from a roof. He did it, knowing it wouldn’t hurt. The case of the Pakistani boy with a rare genetic disorder was described in 2006. He could feel warmth and cold and the texture of objects. But he never felt pain. Now scientists have paired the discovery with the gene-editing tool CRISPR, in what they say is a step toward a gene therapy that could block severe pain caused by diabetes, cancer, or car accidents without the addictive effects of opioids.”

21 August Masatoshi Toda Rain-resistant wheat variety developed using genome editing http://www.asahi.com/ajw/articles/AJ201908210010.html.

“Scientists have created a rain-resistant wheat variety using genome-editing technology, a breakthrough that could lead to the development of higher-quality flour. The research team from the National Agriculture and Food Research Organization (NARO) and Okayama University said genome editing enabled them to develop the variety in just about a year. It takes nearly 10 years to develop such a wheat species using conventional breeding technology because the plants must be bred over generations. The wheat used for the study is not a species currently sold on the market, but the team believes the method utilized could someday succeed in developing an edible variety resistant to rain. “The variety we developed has excellent properties, so we’ll use it as a parent to create new species through breeding,” a team member said.”

“While most organic food producers view rejection of technology as a way to set their “natural” products apart from the conventional alternatives, they have miscalculated the importance of plant breeding advances and may put themselves at a severe competitive disadvantage as a result. NBTs are beginning to radically improve food production, yielding products that appeal to both consumers and farmers. This feat cannot be replicated by organic growing practices.”

14 August: Tina Hesman Saey CRISPR enters its first human clinical trials: The gene editor targets cancer, blood disorders and blindness https://www.sciencenews.org/article/crispr-gene-editor-first-human-clinical-trials.

“In the first spate of clinical trials, scientists are using CRISPR/Cas9 to combat cancer and blood disorders in people. In these tests, researchers remove some of a person’s cells, edit the DNA and then inject the cells back in, now hopefully armed to fight disease. Researchers are also set to see how CRISPR/Cas9 works inside the human body. In an upcoming trial, people with an inherited blindness will have the molecular scissors injected into their eyes. Those tests, if successful, could spur future trials for Duchenne muscular dystrophy, cystic fibrosis and a wide variety of other genetic diseases, affecting millions of people worldwide.”

“A few weeks ago, scientists from 127 research institutes across Europe that group some 25,000 scientists demanded that the EU authorities urgently change the legislation on genetically modified organisms (GMOs), transgenics. In an open letter addressed to the European Parliament, the European Commission and the Council, scientists warn that the current regulation leaves Europe out of play in the face of the possibility of designing new plant varieties using CRISPR to create “sustainable agriculture” in the context of climate change with drought-resistant varieties that need less water and pesticides. “The ability to use genetic editing is crucial for the well-being and food security of European citizens,” the text claimed.”

8 August 2019: Jose A. Bernat Crispr Can Help Solve Our Looming Food Crisis — Here’s How — There’s not enough land to feed everyone on Earth without ruining the climate, a new IPCC report shows. Gene-edited crops could help reduce agriculture’s footprint. https://www.wired.com/story/gene-editing-food-climate-change/?verso=true.

“To have a shot at truly combating climate change, countries around the world are going to have to finally face the dirt-encrusted, fertilizer-soaked, methane-farting elephant in the room: agriculture… And though far from a cure-all, the potential for gene editing to make every acre of land more productive even in the face of climate change has captured the imagination of plant scientists, the agtech industry, and governments alike. These days, they’re placing ever-bigger bets on Crispr’s ability to future-proof the world’s food supply from the threats of an increasingly unpredictable environment.”

“The lights are burning late at CRISPR labs around the world. In 2012, the year researchers transformed a bacterial immune system into the fast and versatile tool for genome engineering, scientific publications mentioning CRISPR totaled 127. Since then there have been more than 14,000. Although the United States has had the most CRISPR publications — and continues to have the most cited papers — China is now a close second and is pouring money into CRISPR’s uses. With support from the Pulitzer Center, Science visited scientists in five Chinese cities who are harnessing CRISPR in a wide range of disciplines. China’s biggest push is in agriculture but researchers there are also applying the editor on a large scale in animals, with pig organs for human transplants the most provocative goal. And China is aggressively exploring genome editing in medicine, having launched far more clinical trials using CRISPR, mainly for cancer, than any country.”

“The Broad Institute of MIT and Harvard lied about who invented the use of CRISPR genome editing in animal cells, and its lead CRISPR scientist Feng Zhang made statements to the patent office that he knew were “untrue,” attorneys for the University of California and its partners claim in legal documents filed Tuesday night with the U.S. Patent and Trademark Office. In strikingly tough language, the lawyers accused the Broad of trying to “deceive the Office” in order to win patents on the revolutionary technology, claimed another Broad scientist made a “materially false declaration” about when Zhang’s lab got CRISPR to work, and argued that Zhang didn’t know what molecules the genome editor needed until he read a rival’s key paper — all of which makes Zhang’s work “unpatentable.””

“China now has at least four groups of CRISPR researchers doing gene editing with large colonies of monkeys. “The most startling part of what is coming out of China is seeing how they have just a brute-force approach,” says reproductive biologist Jon Hennebold at the Oregon National Primate Research Center in Hillsboro. “The level of animal support they have to do those experiments is really astounding.” It’s not just monkeys. China’s researchers have racked up a long list of CRISPR firsts in dogs, mice, rats, pigs, and rabbits. That research promises higher quality meats, disease-resistant livestock, and new medical treatments and organs for human transplantation. So far, many of the animals are simply proofs of concept. Despite the multitude of CRISPR-altered monkeys, for example, Chinese teams have published “very little follow-up in terms of characterizing what these mutations mean from a [disease] model or a treatment perspective,” Hennebold says.”

“Victoria Gray is waiting patiently in a hospital room at the Sarah Cannon Research Institute in Nashville. “It’s a good time to get healed,” she says. The 34-year-old from Forest, Miss., has struggled with sickle cell disease throughout her life. Gray is at the hospital because she volunteered for one of the most anticipated medical experiments in decades: the first attempt to use the gene-editing technique CRISPR to treat a genetic disorder in the U.S. She’s the first patient ever to be publicly identified as being involved in such a study. “I always had hoped that something will come along,” Gray says in an exclusive interview with NPR. “It is just amazing how far things have come. I just want to kind of help bring awareness to this disease and let other people know that there is hope.””

“IN BEIJING AND DURHAM, NORTH CAROLINA — If Gao Caixia were a farmer, she might be spread a little thin. Down the hall from her office at a branch of the Chinese Academy of Sciences (CAS) here in Beijing, seeds from a strain of unusually soft rice and a variety of wheat with especially fat grains and resistance to a common fungus sprout in a tissue culture room. A short stroll away, wild tomato plants far hardier than domestic varieties but bearing the same sweet fruit crowd a greenhouse, along with herbicide-resistant corn and potatoes that are slow to brown when cut. In other lab rooms Gao grows new varieties of lettuce, bananas, ryegrass, and strawberries. But Gao isn’t a farmer, and that cornucopia isn’t meant for the table — not yet, anyway. She is a plant scientist working at the leading edge of crop improvement. Every one of those diverse crops has been a target for conventional plant breeders, who have slowly and painstakingly worked to endow them with traits to make them more productive, nutritious, or hardy. But Gao is improving them at startling speeds by using the genome editor CRISPR.

“Patients are about to be enrolled in the first study to test a gene-editing technique known as CRISPR inside the body to try to cure an inherited form of blindness. People with the disease have normal eyes but lack a gene that converts light into signals to the brain that enable sight. The experimental treatment aims to supply kids and adults with a healthy version of the gene they lack, using a tool that cuts or “edits” DNA in a specific spot. It’s intended as a onetime treatment that permanently alters the person’s native DNA.”

“Having learned about the need to reconsider well-entrenched ways of thinking from past debates on the regulation of new technologies, we support initiatives that advance a broad stakeholder and societal debate on the future use of genome editing in Europe… Bayer, along with leading scientists, asks for an EU-wide regulatory approach to genome-edited plants that considers not only the technical process of breeding and development, but, more importantly, the end product of that process too.”

“Today, on the anniversary of the decision of the Court of Justice of the European Union (CJEU) on plant breeding with the help of gen-editing, an open letter was sent to the Swedish European parliamentarians and the Swedish government. The letter is a call to action for an expedited change of the European legislation for genetically modified organisms (GMO). It has been signed by the leaders of 14 Swedish universities/research centres, royal science academies or research financiers as representatives of the independent Swedish research community.”

“Gene-edited tomatoes that are resistant to common viruses can be introduced into the U.S. without coming under federal regulations for genetically engineered plants. The USDA has determined that six tomato lines developed by Nexgen Plants of Australia aren’t potential plant pests and thus don’t fall under the agency’s jurisdiction for regulating biotech crops. Nexgen altered the tomatoes with “particle bombardment” of gene sequences that allows the plants to detect and destroy the tomato spotted wilt virus and cauliflower mosaic virus.”

23 July: Heide Ledford CRISPR conundrum: Strict European court ruling leaves food-testing labs without a plan https://www.nature.com/articles/d41586-019-02162-x

“A landmark European court ruling that made gene-edited crops subject to the same stringent regulations as other genetically modified organisms (GMOs) has created a conundrum for food-testing laboratories across Europe. The ruling that the Court of Justice of the European Union (ECJ) delivered on 25 July 2018 requires these scattered laboratories — which already spot-check freighters and supermarkets for foods that contain unapproved GMOs — to look for gene-edited crops. But there is no easy way to do this. Gene edits often alter just a few DNA letters, whereas conventional genetic modifications often involve transplanting longer stretches of DNA from one species to another. “Some of these [gene-editing] alterations are small enough that they are simply indistinguishable from naturally occurring organisms,” says Martin Wasmer, who studies the legal aspects of genome editing at the Leibniz University Hannover, Germany. “It will not be possible to enforce in those cases.” Scientists struggle to detect the unauthorized sale of gene-edited crops whose altered DNA can mimic natural mutations.”

23 July: Ron Bailey E.U. Regulators Can’t Detect the Gene-Edited Crops They Banned The difference between two identical genes — one edited and the other a natural mutation — is entirely metaphysical. https://reason.com/2019/07/23/e-u-regulators-cant-detect-the-gene-edited-crops-they-banned/.

“The European Court of Justice ruled last summer that the European Union’s absurd regulatory scheme for genetically modified organisms (GMOs) must be applied to gene-edited crops. Such regulations, however, are scientifically nonsensical. GMO crops (typically modified by adding genes from other organisms)and gene-edited crops (using techniques like CRISPR to modify genes already in the crop variety) are safe for people and for the environment. Such crops need no more regulation than do crops created via conventional techniques such as crossbreeding or random mutation by blasting them with ionizing radiation and harsh chemicals. Now foods labs are telling would-be E.U. regulators that there are no tests that can reliably distinguish between gene-edited and conventional crop varieties. Why? Because many of the edited genes are indistinguishable from those in naturally occurring organisms. Consequently, E.U. regulators are worried that gene-edited horrors from the U.S., such as Calyxt’s healthy high-oleic-acid oil or Intrexon’s non-browning lettuce, might sneak into European supermarkets undetected.”

“Risk-disproportionate regulation of gene-edited crops has been proposed to gain public acceptance for this breeding technique. However, confounding safety regulations with advocacy for an underlying technology risks weakening achievement of both objectives. Dedicated factual communication and education from trusted sources is likely to better support public acceptance of gene-edited crops.”

12 July: Zachery Eanes This RTP startup is using gene editing to improve crops, from corn to raspberries https://www.newsobserver.com/news/business/article232437938.html.

“As Tom Adams sees it, there are two main problems in the world related to food. There are those who don’t have enough of it and there are others that have too much of the wrong stuff. He’s hoping his startup, nestled near the center of Research Triangle Park, can be a part of changing that equation. Just over a year old, Pairwise is at the forefront of agriculture technology, creating experimental crops that might one day show up on the shelves at your grocery store. The company uses CRISPR technology — most famous for its controversial use by a Chinese scientist in an attempt to make two unborn children resistant to HIV — to create plants that are, in the words of Pairwise’s head of trait development, Mike Mann, “more affordable, attainable and also convenient.” Adams, the company’s CEO, thinks if they can improve produce in slight ways, it will help people “go to the produce aisle instead of the potato chip aisle.””

“Though researchers are turning to gene editing to address animal welfare issues, it appears that activists remain lukewarm to that use of the technology. Hornless dairy cows, disease-resistant swine and poultry, male pigs that never reach puberty and cattle that can better tolerate heat are some of the projects now in the works to reduce suffering among livestock. Animal welfare groups, however, are treading carefully and appear hesitant to embrace precision breeding, even when it’s intended to spare livestock from painful procedures. This raises the question of whether they’ll ever endorse research aimed at improving conditions for livestock under the current methods of agricultural production.”

4 July: Elinor Hortle Why the ‘molecular scissors’ metaphor for understanding CRISPR is misleading https://theconversation.com/why-the-molecular-scissors-metaphor-for-understanding-crispr-is-misleading-119812.

“…the molecular scissors metaphor is pretty damn accurate as far as it goes. But in focusing on the relatively simple relationship between CRISPR and DNA, we miss the far more complicated relationship between DNA and the rest of the body. This metaphor ignores an entire ecosystem of moving parts that are crucial for understanding the awe-inspiring, absolutely insane thing scientists are trying to do when they attempt gene editing. I prefer the metaphor of malware. In my research I use CRISPR from time to time. To design experiments and interpret results effectively, I need a solid way to conceptualise what it can (and can’t) do. I do not think of CRISPR as molecular scissors. Instead I imagine a city. The greater metropolis represents the body, the suburbs are organs, the buildings are cells, the people are proteins, and the internet is DNA. In this metaphor CRISPR is malware. More precisely, CRISPR is malware that can search for any chosen 20-character line of code and corrupt it. This is not a perfect metaphor by any stretch, but it gets me closer to understanding than almost anything else.”

“A team of scientists from the Technical University of Dortmund, Germany have figured out a way to grow tobacco plants that contain 99.7 percent less nicotine. They used the popular gene-editing technique CRISPR to disable six enzymes in the plant that aid in the production of the addictive stimulant. According to the researchers, the new version has just 0.04 milligrams of nicotine per gram — almost undetectable. Their research was published by the Plant Biotechnology Journal earlier this month.”

“The new biotechnologies, called “editing” of genes (or rewriting genes) are now present in the basic research laboratories of biology. Various applied domains also seem promising. However, optimism on this topic was showered with a decision last year by the Court of Justice of the European Union (CJEU) stating that the organisms obtained by these new technologies, including mutagenesis (the simplest use of gene editing), which is sometimes indistinguishable from natural mutations, should be regulated as GMOs. As a result, the EU directive on GMOs could again rein in innovation, as is the case with classical transgenesis. Plant breeding companies are considering relocating their mutagenesis programs outside Europe “if nothing is done to change EU rules”.”

“The knockdown of the three most highly expressed BBL genes [encoding the synthesis of nicotine] …resulted in a reduction of the nicotine content without increasing the content of other alkaloids (Kajikawa et al., 2011; Lewis et al., 2015)… Thus, the simultaneous knockout of these BBL genes is a promising approach to generate a nicotine‐free tobacco plant.”

“GlaxoSmithKline’s latest move to reinvigorate R&D is a collaboration with two of the biggest names in CRISPR research to develop new gene editing technologies and use them to identify drug targets. GlaxoSmithKline plc (LSE:GSK; NYSE:GSK) teamed up with the labs of Jennifer Doudna at the University of California Berkeley and Jonathan Weissman at the University of California San Francisco to form the Laboratory for Genomics Research (LGR), a physical laboratory near UCSF’s Mission Bay campus that will bring together investigators from all three partners.”

11 June: The White House Executive Order on Modernizing the Regulatory Framework for Agricultural Biotechnology Products https://www.whitehouse.gov/presidential-actions/executive-order-modernizing-regulatory-framework-agricultural-biotechnology-products/?utm_source=link&utm_medium=header.

“Recent advances in biotechnology have the potential to revolutionize agriculture and thereby enhance rural prosperity and improve the quality of American lives. Biotechnology can help the Nation meet its food production needs, raise the productivity of the American farmer, improve crop and animal characteristics, increase the nutritional value of crop and animal products, and enhance food safety. In order to realize these potential benefits, however, the United States must employ a science-based regulatory system that evaluates products based on human health and safety and potential benefits and risks to the environment. Such a system must both foster public confidence in biotechnology and avoid undue regulatory burdens.”
