Central regulatory role for the RpoS sigma factor in expression of Salmonella dublin plasmid virulence genes.

Journal of bacteriology - 1 Sept 1995

Chen C Y, Buchmeier N A, Libby S, Fang F C, Krause M, Guiney D G

Abstract excerpt

The plasmid virulence genes spvABCD of Salmonella spp. are regulated by SpvR and the stationary-phase sigma factor RpoS. The transcription of spv genes is induced during the post-exponential phase of bacterial growth in vitro. We sought to investigate the relationship between growth phase and RpoS in spv regulation. rpoS insertion mutations were constructed in S. dublin Lane and plasmid-cured LD842 strains, and...
