Abstract
Sporulation and competent cell formation have been studied in four Bacillus subtilis strains, carrying septum-initiation mutations of different loci, div-31, div-341, div-12 and div-355 which exhibit filamentous growth at 45° C. The div-31 mutant was found to be defective in competence development at 30°–40°C whereas the div-12 mutant was affected only slightly. The div-341 and div-355 mutants showed lower competence, particularly at the higher temperatures. The four div mutant strains all showed poor sporulation at higher temperatures compared to the wild-type strain. We propose that some of the initial steps of septation are involved both in sporulation (possibly in forespore septum formation) and in competent cell formation and that these two processes share certain common features distinct from those in vegetative cell division.
