Expression of the ^F-Directed csfB Locus Prevents Premature Appearance of ^G Activity during Sporulation of Bacillus subtilis

Department of Microbiology and Immunology, Temple University School of Medicine, Philadelphia, Pennsylvania 19140

Received 6 August 2007/ Accepted 25 September 2007

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