“…The medium-dependent effect on sporulation in this mutant (hardly any spores were produced on nutrient agar plates), suggests that YdcC protein becomes essential for spore formation only under certain environmental conditions. A similar phenomenon has been reported previously for mutation of the spoIIAB and spoIIQ genes (Foulger et al, 1995;Sun et al, 2000). The increased s K activity found in the yhbH mutant suggests that the yhbH gene, which encodes a soluble protein, might be involved directly or indirectly in repression of certain s K -dependent genes.…”

Identification of sporulation genes by genome-wide analysis of the σ E regulon of Bacillus subtilis

2003

Differentiation in the spore-forming bacterium Bacillus subtilis is governed by the sequential activation of five sporulation-specific transcription factors. The early mother-cell-specific transcription factor, s E , directs the transcription of many genes that contribute to the formation of mature, dormant spores. In this study, DNA microarrays were used to identify genes belonging to the s E regulon. In total, 171 genes were found to be under the control of s E . Of these, 101 genes had not previously been described as being s E dependent. Disruption of some of the previously unknown genes ( ydcC, yhaL, yhbH, yjaV and yqfD) resulted in a defect in sporulation.
