The USDA Animal and Plant Health Inspection Service (APHIS) has invited public comment on Corteva’s application for the deregulation of its GM maize event DP202216. Maize varieties containing event DP202216 have been genetically modified to increase and extend the expression of the zmm28 gene, reportedly resulting in maize with enhanced grain yield potential. In addition, the varieties also possess tolerance to the herbicide glufosinate.
