Ep96 - Insect resistance in traditional corn: First report of cross-pollination with BT corn in the Philippines

I talked with Ms. Angelyn Marmeto about her study on the genetic interaction between BT corn and traditional maize varieties in the Philippines. Their team discovered the first evidence of natural cross-pollination, where insect-resistant traits from genetically modified corn were transferred to a native variety known as Silangan. We discuss how this gene flow happened, what it means for insect resistance, and the broader implications for agricultural biotechnology and biosafety in the country.
