Genome Editing in Agriculture:
Methods, Applications, and Governance
A paper in the series on
The Need for Agricultural Innovation to
Sustainably Feed the World by 2050
July 9, 2018…Council for Agricultural Science and Technology, Ames, Iowa
Twentieth-century advances in plant and animal breeding did much to help meet the increasing food, fiber, feed, and fuel needs of an expanding world. But continued population growth, resource shortages, climate change, and pest prevalence make sustainability a daunting yet essential task. Genome editing is a powerful new method that enables unprecedented control over genetic material and offers the opportunity to make rapid advances that influence agricultural practices.
 
Led by Task Force Chair Adam J. Bogdanove, the authors of this issue paper focused their attention on a tool that can increase the positive impacts of plant and animal breeding on human welfare and sustainability. Genome editing is a process used to make precisely targeted changes in the DNA (deoxyribonucleic acid) of living cells and organisms. Due to recent advances, this method is widely applicable and offers the opportunity to rapidly advance basic and applied biology.

This issue paper addresses the concept by explaining
  • how genome editing is performed,
  • what types of edits can be made,
  • how the process relates to traditional breeding and other means of genetic modification,
  • what potential limitations may arise with this approach, and
  • what current factors affect the governance of gene editing.

Although much remains to be learned, it is clear that successful development of genome editing for crop and livestock improvement will benefit from science-informed, value-attentive regulation that promotes both innovation and transparency. The authors of this paper intended for it to be a resource in providing a conceptual and knowledge-based foundation for regulatory agencies, policymakers, private and public research institutions, industry, and the general public.
