CAST papers are the foundation of CAST’s science communication work. Developed by expert-led task forces, these peer-reviewed publications translate agricultural science into trusted insights that inform policy, guide public understanding, and fuel CAST programs, dialogues, and educational initiatives.
This Issue Paper identifies the nature of gene flow and discusses the relatively limited situations in which it is likely to cause economic problems in the production of commercial biotech crops. The paper explains how gene flow relates to adventitious presence, describes the biological traits being imparted into biotech crops, summarizes present risk assessment and regulatory mechanisms, and discusses potential economic effects and policy and research ramifications of gene flow of commercial biotech crops.
