Identification of a gene associated with Bt resistance in Heliothis virescens.

Science (New York, N.Y.) - 3 Aug 2001

Gahan L J, Gould F, Heckel D G

Abstract excerpt

Transgenic crops producing insecticidal toxins from Bacillus thuringiensis (Bt) are widely used for pest control. Bt-resistant insect strains have been studied, but the molecular basis of resistance has remained elusive. Here, we show that disruption of a cadherin-superfamily gene by retrotransposon-mediated insertion was linked to high levels of resistance to the Bt toxin Cry1Ac in the cotton pest Heliothis...
