Activation of Bt Protoxin Cry1Ac in Resistant and Susceptible Cotton Bollworm

Activation of Bt Protoxin Cry1Ac in Resistant and Susceptible Cotton Bollworm

Show other versions (1)

Crystalline (Cry) proteins from Bacillus thuringiensis (Bt) are used extensively for insect control in sprays and transgenic plants, but their efficacy is reduced by evolution of resistance in pests. Here we evaluated reduced activation of Cry1Ac protoxin as a potential mechanism of resistance in th...
