GENE CRY7BAL ENCODING AN INSECTICIDAL CRYSTAL PROTEIN OF BACILLUS THURINGIENSIS.

摘要

The present invention discloses the isolation, cloning and use of genes of insecticidal crystal proteins from Bacillus thuringiensis. The present invention isolates a novel insecticidal crystal protein gene cry7Bal from B. thuringiensis subsp. huazhongensis YBT-978 strain, and said gene encodes a novel insecticidal crystal protein Cry 7BaI, which shows insecticidal activity against Lepidopteran insects. The present invention also discloses the gene sequence of the novel insecticidal crystal protein, uses suitable expression vectors to transform micro-organisms so as to express the product Cry7Bal encoded by the gene and make it exert the insecticidal activity of the protein against Lepidopteran pests.
