WebJul 10, 2007 · Phosphate limitation in Streptomyces and in other bacteria triggers expression changes of a large number of genes. This response is mediated by the two-component PhoR–PhoP system. A Streptomyces coelicolor ΔphoP mutant (lacking phoP) has been obtained by gene replacement.A genome-wide analysis of the primary response to … WebMay 20, 2013 · The pmrA mutant displayed heightened expression of SsrB-dependent genes and faster Spi/Ssa-dependent macrophage killing than wild-type Salmonella. A mutation in the ssrB promoter that abolished repression by the PmrA protein rendered Salmonella as hypervirulent as the pmrA null mutant.
