FIG. 2.
Levels of gerAA, gerBA, and gerKA mRNA with or without induction of σG synthesis during vegetative growth of B. subtilis. B. subtilis strain PS766 (Pspac-sigG) was grown, RNA was isolated at various times with or without induction of σG synthesis by addition of IPTG, and levels of various RNAs were quantitated as described in the text. Symbols: ○ and •, gerKA mRNA; □, gerBA mRNA; ▵, gerAA mRNA; ○, □, and ▵, with IPTG induction; and •, without IPTG induction. The vertical arrow denotes the time of IPTG addition.
