Insertional mutations in the spo0A and spoIIAC genes of Bacillus sphaericus 2362 were prepared by conjugation with Escherichia coli using a suicide plasmid containing cloned portions of the target genes. The mutants resembled their Bacillus subtilis counterparts phenotypically and were devoid of crystal proteins as determined by electron microscopy, SDS-PAGE and Western blots. The mutants had greatly reduced toxicity to anopheline mosquito larvae compared to the parental strain. We conclude that crystal protein synthesis in this bacterium is dependent on expression of early sporulation genes.
