Abstract
During sporulation, sigma(G) becomes active in the prespore upon the completion of engulfment. We show that the inactivation of the sigma(F)-directed csfB locus resulted in premature activation of sigma(G). CsfB exerted control distinct from but overlapping with that exerted by LonA to prevent inappropriate sigma(G) activation. The artificial induction of csfB severely compromised spore formation.Keywords
