Abstract

The present disclosure relates to a gene sequence Cry1Ab/Cry1AcZM, an expression cassette containing the gene, an expression vector, a host cell and the use thereof in plant breeding. The protein encoded by an insect-resistant gene according to the disclosure can be expressed in a monocotyledonous plant and further used for culturing an insect-resistant transgenic monocotyledonous plant harboring transgenes Cry1Ab/Cry1AcZM. Bioassay tests prove that the modified and synthesized gene sequence Cry1Ab/Cry1AcZM and the expression product of the constructed vector according to the disclosure have a killing effect on lepidopteran pests.
