title: [Characterization of the insecticidal crystal protein genes of Bacillus thuringiensis YBT-1520].
abstract: The insecticidal crystal protein genes of highly toxic Bacillus thuringiensis YBT-1520 were analyzed. Southern hybridization and PCR analysis indicated that this strain bears cry1Aa, cry1Ab, cry1Ac and cry2 genes. The copy number of three cry1A genes is different and cry1Ac gene (here named cry218) is the highest. The restriction location of three genes is different from that in typical strains, such as HD-1 and HD-73 strains. 4190 bp nucleotide sequence of cry218 gene was determined and this gene was named cry1Ac10 in the recently published gene nomenclature.
