Summary The spollIG gene encodes a sigma factor that determines prespore‐specific gene expression during sporulation in Bacillus subtilis. Correct spatial and temporal expression of the spollIG gene depends on a number of other sporulation ( spo ) genes, but only one of these genes, spollIE , has a specific effect on spollIG expression and not on gene expression in the other differentiating cell, the mother cell. However, the spollIE gene is expressed predominantly before differentiation begins. Thus, its product must play an important role in sensing or determining the spatial localization of prespore‐specific gene expression in this system.
