Although sigma factor-dependent transcriptional regulation was shown to be essential for adaptation to different environmental stimuli, no such sigma factor has been related to the regulation of the cold shock response in Bacillus subtilis. In this study, we present genetic evidence for participation of sigma(L) (sigma(54)) and the two sigma(L)-dependent transcriptional enhancers BUR and YplP in the cold shock response of Bacillus subtilis JH642. Single-gene deletion of either sigL, bkdR, or yplP resulted in a cold-sensitive phenotype.
