BACILLUS THURINGIENSIS CRYIIA-TYPE GENE, TRANSFORMED MICROORGANISMS AND NETHODS FOR PRODUCING CRYIIA-TYPE PROTEIN

摘要

This invention relates to a crystalline protein toxin useful as a biological insecticide which is known as P-2 toxin, or P-2 delta-endotoxin and which is produced by Bacillus thuringiensis. More specifically, this invention relates to the cloning and expression in various microorganisms of the gene coding for the P-2 delta-endotoxin, and related novel insecticide compositions incorporating P-2 toxin.
