We have found that sporulation in Bacillus subtilis crsA47 mutants does not require the ^H-dependent promoter of the spo0A gene. This implies that the glucose-resistant sporulation phenotype of this strain is not related to the switch from the vegetative-stage ^A-dependent promoter to the ^H-dependent promoter at the spo0A gene.
