Novel DNA-Based Methods for Detection of Bt-Resistant Fall Armyworms
University of Tennessee Professor Juan Luis Jurat-Fuentes led a team of researchers who identified a particular DNA mutation in a gene that provides fall armyworms with field resistance to Bt corn. The team was also able to track changes in the mutant gene frequency in fall armyworm populations in Puerto Rico, the first successful case of DNA-based detection of insects exhibiting emerging field-evolved practical resistance to a transgenic Bt crop.
NIFA supports this research through the Biotechnology Risk Assessment Grant program (BRAG) and the Agriculture and Food Research Initiative (AFRI).
