Abstract excerpt
Alternative sigma factors have been detected in the myxobacterium Stigmatella aurantiaca during indole-induced sporulation, fruiting body formation and heat shock using an antiserum raised against sigma factor SigB. The time course of sigB gene expression was analysed by RT-PCR and by determining beta-galactosidase activity during development in a merodiploid strain that harboured a sigB-lacZ fusion gene....
