A Novel Inducible Expression Cry2Ab Insecticidal Gene and Its Applications

The present invention discloses a novel inducible Cry2Ab‑1 insecticidal gene, which was obtained by random mutagenesis of the Cry2Ab gene sequence using error‑prone PCR. The resulting sequence exhibits 98.9% identity to the original sequence and shows low homology with known allergens, thus posing no allergenic risk. When the inducibly expressed protein was tested against the oriental armyworm, it induced a mortality rate of 93.33% in the larvae, while also severely inhibiting the growth of surviving individuals. These results demonstrate that the expressed protein possesses potent insecticidal activity and can serve as a candidate gene for breeding transgenic insect‑resistant plants and constructing engineered microbial strains.
