Enhancing Cry1Ac toxicity by expression of the Helicoverpa armigera cadherin fragment in Bacillus thuringiensis.

Insect cadherin proteins localized in the midgut epithelium were identified as receptors for Bacillus thuringiensis insecticidal crystal proteins (Cry toxins). These cadherins facilitated toxin monomer oligomerization and mediated oligomer binding to secondary receptors. It has been reported that Manduca sexta, Helicoverpa armigera, Anopheles gambiae and… CONTINUE READING
