The Bacillus subtilis SpoVE integral membrane protein is essential for the heat resistance of spores, probably because of its involvement in spore peptidoglycan synthesis. We found that an SpoVE-yellow fluorescent protein (YFP) fusion protein becomes localized to the forespore during the earliest stages of engulfment, and this pattern is maintained(More)
Two highly similar RNA polymerase sigma subunits, σ(F) and σ(G), govern the early and late phases of forespore-specific gene expression during spore differentiation in Bacillus subtilis. σ(F) drives synthesis of σ(G) but the latter only becomes active once engulfment of the forespore by the mother cell is completed, its levels rising quickly due to a(More)
