Abstract excerpt

We cloned the cryIA(a) gene from Bacillus thuringiensis strain FU-2-7, one of the toxin genes encoding lepidopteran-specific protoxins. Sequence analysis of the gene showed two amino acid differences (Pro77 to Leu and Phe965 to Ser) from the CryIA(a) of B. thuringiensis strain HD-1. We constructed chimaeric cryIA(a) genes using FU-2-7 and HD-1 cryIA(a) genes and isolated the chimaeric protoxins, as well as the...
