Abstract excerpt

OBJECTIVE: To obtain the mutants with different toxicity from the wild-type CrylCa7. METHODS: Insecticidal crystal protein CrylCa7 from Bacillus thuringiensis which is highly toxic to Spodoptera exigua, an important agricultural pest in China, and we mutated this toxin by over-lapping extensive PCR method in different domains to obtain 11 chimeric mutants. RESULTS: The results of bioassays against Spodoptera...
