Various genome-editing technologies have been embraced by plant breeders across the world as promising tools for the improvement of different crops to deliver consumer benefits, improve agronomic performance, and increase sustainability. The uptake of genome-editing technologies in plant breeding greatly depends on how governments regulate its use. Some major agricultural production countries have already developed regulatory approaches that enable the application of genome editing for crop improvement, while other governments are in the early stages of formulating policy. Central to the discussion is the principle of "like products should be treated in like ways" and the subsequent utilization of exclusions and exemptions from the scope of GMO regulations for these products. In some countries, the outcomes of genome editing that could also have been achieved through conventional breeding have been defined as not needing GMO regulatory oversight. In this paper, we provide a short overview of plant breeding and the history of plant biotechnology policy development, the different classes of current regulatory systems and their use of exemptions and exclusions for genome-edited plants, and the potential benefits of such approaches as it relates to achieving societal goals.
