India ranks second in the global cotton balance, next only China. Cotton is mainstay of India’s textile industry, accounting for roughly 74% total mill usage. production has increased due to introduction and rapid geographical expansion bollworm resistant Bt cotton. The objective this paper compare balance analyses investigate factors that have influenced development over last 22 years. pertine...

Laboratory-selected Bacillus thuringiensis-resistant colonies are important tools for elucidating B. thuringiensis resistance mechanisms. However, cotton bollworm, Helicoverpa zea, a target pest of transgenic corn and cotton expressing B. thuringiensis Cry1Ac (Bt corn and cotton), has proven difficult to select for stable resistance. Two populations of H. zea (AR and MR), resistant to the B. th...

The idea of enhanced methanol production from cell wall by pectin methyl esterase enzymes (PME) combined with expression cry genes Bacillus thuringiensis as a strategy to improve insect pest control in cotton is presented. We constructed cassette containing two (cry1Fa and Cry32Aa) pme genes, one Arabidopsis thaliana (AtPME), other Aspergillus. niger (AnPME) pCAMBIA1301 plant vector using CAMV-...

Transgenic maize expressing toxins derived from the bacterium Bacillus thuringiensis (Bt) may be commercially planted in northern China where Bt cotton has been for more than two decades. While brings additional benefits insect control, it complicates resistance management of bollworm (CBW), Helicoverpa armigera (Lepidoptera, Noctuidae), a common target and maize. Here we developed two-locus po...
