Binding and competition of five Bacillus thuringiensis toxins—Cry1Ab, Cry1Ac, Cry1Ba, Cry1Ca, and Cry1Ea—for midgut binding sites from three pests, Spodoptera frugiperda, Diatraea saccharalis, and Diatraea grandiosella, were investigated as part of a strategy to develop tropical transgenic maize resistant to several stemborers. On S. frugiperda, Cry1Ab and Cry1Ac compete for the same binding site; Cry1Ba and Cry1Ca compete for a second binding site. Cry1Ea recognizes a third specific binding… CONTINUE READING
