Molecular and cytological analysis of the expression of<i>Streptomyces</i>sporulation regulatory gene<i>whiH</i>

7 Feb 2013

Abstract excerpt

The whiH gene is required for the orderly sporulation septation that divides aerial hyphae into spores in Streptomyces coelicolor. Here, we use a whiHp-mCherry transcriptional reporter construct to show that whiHp is active specifically in aerial hyphae, fluorescence being dependent on sporulation sigma factor WhiG. The results show that the promoter is active before the septation event that separates the...
