New CAST Paper Addresses the Implications of Gene Flow related to Commercial Use of Biotech Crops

December, 2007 … Ames, Iowa. The Council for Agricultural Science and Technology (CAST) is releasing a new Issue Paper, Implications of Gene Flow in the Scale-up and Commercial Use of Biotechnology-derived Crops: Economic and Policy Considerations.

Gene flow is a natural occurrence in the biological world and always has been. The introduction of biotechnology-derived crops, however, has caused an increased interest in understanding and managing gene flow. According to Task Force Chair David Gealy, USDA–ARS, “Humans have selected, adapted, and improved crops from diverse species for numerous purposes.  Many useful traits are being imparted into biotech and nonbiotech crops, most of which are likely to impact the dynamics of gene flow very little, especially outside of agricultural fields. Precommercialization procedures that take into account the specific trait being introduced will help to insure that impacts of gene flow remain low.” The Issue Paper:

“Science and technology have played a significant role in how the U.S. and other world markets produce crops,” noted CAST Executive Vice President John Bonner. “This new paper offers insight regarding the gene flow potential and economic implications of such crops, and CAST is pleased to help facilitate this important discussion.”  \
