Disruption of a sigma factor gene, sigF, affects an intermediate stage of spore pigment production in Streptomyces aureofaciens.

FEMS microbiology letters - 15 Aug 1997

Rezuchová B, Barák I, Kormanec J

Abstract excerpt

The Streptomyces aureofaciens sigF gene encodes a sigma factor. By integrative transformation, via double cross-over, a stable null mutant of sigF gene was obtained. This mutation appeared to have no obvious effect on vegetative growth, but affected the late stage of spore maturation. Microscopic examination showed that spores were deformed, and spore wall was thinner, compared with the wild-type spores. The...
