Activation of spo0A transcription by sigma H is necessary for sporulation but not for competence in Bacillus subtilis.

Journal of bacteriology - 1 Jun 1994

Siranosian K J, Grossman A D

Abstract excerpt

spo0A and spo0H are needed for the initiation of sporulation and for the development of genetic competence in Bacillus subtilis. Transcription of spo0A initiates from two promoters, Pv and Ps. Pv is active during vegetative growth and is recognized by RNA polymerase containing sigma A. Expression from Ps increases during sporulation and depends on sigma H, the spo0H gene product. A deletion mutation, spo0A delta...
