Corteva seeking deregulation of GM maize line DP202216
Jul. 29, 2019
Pioneer Hi-Bred International, Inc. (Corteva Agriscience’s seed business) is seeking a determination of nonregulated status of a maize event designated as DP202216, which has been genetically engineered for enhanced grain yield potential and glufosinate-ammonium resistance. The petition has been submitted to USDA's Animal and Plant Health Inspection Service (APHIS) in accordance with regulations concerning the introduction of certain genetically engineered organisms and products.
DP202216 maize was generated using Agrobacterium-mediated transformation with plasmid PHP40099 containing the zmm28 and mo-pat gene cassettes. Both the introduced and native zmm28 genes encode the ZMM28 protein, and the increased and extended expression of the ZMM28 protein results in plants with enhanced grain yield potential. DP202216 maize also contains the phosphinothricin acetyltransferase (PAT) protein, which confers resistance to the herbicidal active ingredient glufosinate-ammonium at current labeled rates. DP202216 maize has been field tested in the continental United States and Puerto Rico over 9 years in more than 100 separate plantings as authorized under APHIS permits and notifications.
APHIS will consider all comments that receive on or before September 23, 2019.
