Abstract: A PCR method and a PCR-restriction fragment length polymorphism method were used for identification ofvip1A/vip2A genes andcry1-type genes from Bacillus thuringiensis isolates,respectively.The result showed thatvip1A/vip2A-type genes appeared in 20 of 117 B.thuringiensis isolates.Avip1A/vip2A gene fragment was cloned and sequenced.GenBank accession number is EU594327 Thecry1-type genes were ident ified ascry1Fa.The results indicated that there was some linkage between thevip1A/vip2A andcry1Fa.

Key words: Binary toxin, vip1A /vip2A, vip1A /vip2A-16, PCR-RFLP, cry1Fa
