Abstract

A Bacillus thuringiensis isolate, Bt 2385-1, which showed toxicity to lepidopteran, was isolated from Korean soil sample and characterized. PCR-RFLP showed that this isolate contains two novel cryl-type crystal protein genes. In this study, we designed cryl-type specific primer set (ATG1-F and N400-R) to clone the toxic domain of the all cryl-type genes. The two novel rlyl-type toxin genes in addition to crylJal gene were cloned and sequenced. (omitted)
