ABSTRACT The resistance to the insecticidal protein Cry1Ac from bacterium Bacillus thuringiensis (Bt) in cabbage looper, Trichoplusia ni , has previously been identified be associated with a frameshift mutation ABC transporter ABCC2 gene and altered expression of aminopeptidase N (APN) genes APN1 APN6 shown as missing 110-kDa (phenotype APN1¯) larval midgut brush border membrane vesicles (BBMV). In this study, genetic linkage analysis that APN1¯ phenotype Cry1Ac-resistant T. segregated...
The Cry proteins from Bacillus thuringiensis (Bt) are major insecticidal toxins in formulated Bt sprays and expressed genetically engineered crops for insect pest control. However, the widespread application of field imposes strong selection pressure on target insects, leading to evolution resistance toxins. Identification understanding mechanisms an important approach dissecting modes action providing knowledge necessary development management technologies. In this study, cabbage looper...
