Glucose-Resistant Sporulation in Bacillus subtilis crsA47 Mutants Does Not Depend on Promoter Switching at the spo0A Gene

We have found that sporulation in Bacillus subtilis crsA47 mutants does not require the σ(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 σ(A)-dependent promoter to the σ(H)-dependent promoter at the spo0A gene.
