Bt protein CRY2Ab32 and coding gene and application thereof
2014
The invention provides a Bt protein CRY2Ab32 and a coding gene thereof. The protein is of an amino acid sequence shown in the SEQIDNo.2 or of an amino acid sequence obtained by replacing, missing and/or adding one or more amino acids of the amino acid sequence shown in the SEQIDNo.2, wherein the amino acid sequence is the same as the amino acid sequence shown in the SEQIDNO.2 in activity. The protein can be used for preparing a Bt pesticide, the gene for coding the protein can convert cotton, corns, rice, vegetables and other crops, and the corresponding insect resistant activity is achieved, so that the pesticide using amount is lowered, environment pollution is reduced, and the important economic value and application prospects are achieved.
