Gene Editing Technologies: Importance and Implications for Farmers

Gene Editing Technologies: Importance and Implications for Farmers Drew L. Kershen Earl Sneed Centennial Prof. Emeritus United Soybean Board February 10, 2015 Wayne Parrott, Ph.D., Professor, Plant Breeding and Genomics, Crop & Soil Sciences, University of Georgia, is coauthor of this PowerPoint. Date of Completion January 20, 2015 Policy Issue Plant Breeding Techniques NAS (1987): Several conclusions can be drawn from this review of

the relationship between traditional genetic manipulation techniques and the R-DNA techniques developed during the last 15 years, and of the experience gained from the application of each: There is no evidence that unique hazards exist either in the use of R-DNA techniques or in the movement of genes between unrelated organisms. The risks associated with the introduction of R-DNA engineered organisms are the same in kind as those associated with the introduction of unmodified organisms and organisms modified by other methods. Assessment of the risks of introducing R-DNA engineered organisms into the environment should be based on the nature of the organism and the environment into which it is introduced, not on the method by which it was produced. Policy Issue Plant Breeding Techniques White House OSTP 1992: Exercise of oversight in

the scope of discretion afforded by statute should be based on the risk posed by the introduction and should not turn on the fact that an organism has been modified by a particular process or technique. [O]versight will be exercised only where the risk posed by the introduction is unreasonable, that is, when the value of the reduction in risk obtained by additional oversight is greater than the cost thereby imposed. Policy Issue Plant Breeding Techniques ACRE [UK] (2013): Executive Summary Our understanding of genomes does not support a processbased approach to regulation. The continuing adoption of this approach has led to, and will increasingly lead to, problems. This includes problems of consistency, i.e. regulating organisms produced by some techniques and not others irrespective or

their capacity to cause environmental harm. Our conclusion, that the EUs regulatory approach is not fit for purpose for organisms generated by new technologies, also applies to transgenic organisms produced by traditional GM technology. the potential for inconsistency is inherent because they may be phenotypically identical to organisms that are not regulated. Policy Issue Plant Breeding Techniques Canadian Regulators (2015) Conclusion: It was hypothesized that if insertional effects are found to be similar to other genetic changes that occur in plants, they should present a similar level of risk. We have illustrated here that the insertional effects associated with genetic engineering are similar to the genetic changes that occur in conventionally

bred plants. Based on this similarity, insertional effects should present a similar level of risk as genetic changes associated with conventional breeding. Schnell et al. in references. Regulatory Paradigms Paradigm One Risk, not Hazard; Product (Trait), not Process Presumption that regulation often not needed and should focus on novel, unreasonable risks Science and scientific development trusted and encouraged Paradigm Two Presumption favoring regulation and risk aversion Precautionary Principle Social and Political Consideration should be considered

more important than science and scientific development Politics, not Science Importance and Impacts Paradigm Two will kill directed genetic modification technologies, including synthetic biology, before they have a chance to get started Society (including farmers) deprived of new scientific discoveries Farmers deprived of new technologies Imperative that U.S. regulatory systems move to Paradigm One Presumption against regulation Attitude of confidence in science and scientists Avoidance of burdensome, discriminatory regulations Consumer Perception

Proper scientific education Consumer benefits one example in High-Oleic soybeans and oils Positive labels versus stigmatizing, derogatory labels Access to products rather than threatened boycotts Importance and Impacts Imperative that EU, New Zealand, others, and Cartagena Protocol move to Paradigm One Failure to do so means: Burdensome, discriminatory, unpredictable regulatory system Trade wars e.g. asynchronous approvals; U.S. lawsuits; WTO complaints Veto of science and innovation e.g. China, EU Reluctance to bring to market approved crops/traits Where are the markets in the near-future; short term gain versus longterm gain and vision
