Abstract

The invention relates to a modified mcry2Ab4 gene and its application, and belongs to the technical field of biological control. The modified mcry2Ab4 gene encodes a protein with an amino acid sequence as shown in SEQ ID NO4. The nucleotide sequence is as shown in SEQ ID NO3. By regulating the nucleotide composition of cry2Ab4 gene, its codon frequency is similar to that of a plant gene without changing the encoding amino acid sequence, and the modified gene composition is expressed in plant so as to obtain the resistance to lepidoptera insects.

Description

[0001] This application is a divisional application with the patent application number "2009102420406" and the invention title "modified Bt genes mvip3Aa11, mcry2Ab4, and their gene combinations and applications". Technical field

[0002] The invention belongs to the technical field of biological control, and particularly relates to gene combinations for expressing high virulence proteins to lepidopteran pests, artificially synthesized sequences and applications thereof. Background technique

[0003] Insect pests are one of the important factors causing agricultural production losses. According to statistics, the direct economic loss caused by insect pests to agricultural production is as high as 15% every year. Chemical pesticides have made important contributions to pest control and stable agricultural production. With the increasing awareness of the environmental hazards of chemical pesticides and the increasing awareness of environmental protection, in order to realize the su...
