Regulation of spo0H, an early sporulation gene in bacilli.

E J Dubnau, K Cabane, I Smith
PMCID: PMC211917  PMID: 3102457

Abstract

The construction of lacZ fusions in frame with the spo0H gene of Bacillus licheniformis enabled us to study the expression of this gene under various growth conditions and in various genetic backgrounds. spo0H was expressed during vegetative growth, but the levels increased during early stationary phase and then decreased several hours later. Expression of the gene was not repressed by glucose, but was induced by decoyinine, an inhibitor of guanine nucleotide biosynthesis, which can induce sporulation. Of those tested, the only spo0 gene required for the expression of spo0H was spo0A, and this requirement was eliminated by the abrB mutation, a partial suppressor of spo0A function. spo0H-lacZ expression was much higher in a strain with a deletion in the spo0H gene.
