Expression of kinA and accumulation of sigma H at the onset of sporulation in Bacillus subtilis.

Abstract excerpt

Induction of the Bacillus subtilis kinA gene, which codes for a major kinase of the phosphorelay pathway, required the spo0H gene, coding for the sigma H protein, but not the genes spo0A, spo0B, and spo0F at the onset of sporulation. Also, the levels of sigma H in spo0A, spo0B, and spo0F mutants were increased at the onset of sporulation, though induction of spo0H transcription in all of these mutants was...
