Knockout of SfVipR2 confers Vip3Aa resistance in Spodoptera frugiperda with evidence of genetic complementation among non-allelic mutations of SfVipR1, SfVipR2, and SfCHS2.

Abstract excerpt

The Vip3Aa protein from Bacillus thuringiensis is widely deployed in transgenic crops to control lepidopteran pests, including the fall armyworm Spodoptera frugiperda, a highly invasive, polyphagous pest of global importance. Loss-of-function mutations in SfVipR1 (a thyroglobulin-like gene) and SfCHS2 (chitin synthase 2) have previously been confirmed to confer high-level, recessive resistance to Vip3Aa in S....
