The roles of many sigma factors are unclear in regulatory mechanism of secondary metabolism in Streptomyces. Here, we report the regulation network of a group 3 sigma factor, WhiGch, from a natamycin industrial strain Streptomyces chattanoogensis L10. WhiGch regulates the growth and morphological differentiation of S. chattanoogensis L10. The whiG ch(More)
Quorum sensing molecular γ-butyrolactones (GBL) are widely distributed among the genus Streptomyces. Their cognate receptors have been demonstrated to control secondary metabolism and/or morphological differentiation. ScgA is responsible for the biosynthesis of GBL in Streptomyces chattanoogensis. According to the genome-wide transcriptome analysis of the(More)
Cardiac hypertrophy is often associated with an increased sympathetic drive, and both in vitro and in vivo studies have demonstrated the development of cardiomyocyte hypertrophy in response to either α- or β- adrenergic stimulation. The present study was carried out to determine whether the reversible sodium channel blocker tetrodotoxin (TTX) exerts a(More)
