Sensing wetness: a new role for the bacterial flagellum.

Wang Qingfeng Q Suzuki Asaka A Mariconda Susana S Porwollik Steffen S Harshey Rasika M RM

The EMBO journal 20050505 11

We have uncovered a new role for the bacterial flagellum in sensing external wetness. An investigation into why mutants in the chemotaxis signaling pathway of Salmonella typhimurium exhibit fewer and shorter flagella than wild-type when propagated on a surface, first showed that the mutants downregulate only a small set of genes on swarm media--class 3 or 'late' motility genes, and genes associated with the pathogenicity island SPI-1 TTSS (type three secretion system). Based on observations that ...[more]

Salmonella typhimurium igaA(T191P) and related

Project description:We have exploited a spontaneously isolated mutant IgaA(T191P) that is near-maximally activated for the Rcs system, to identify a vast set of genes that respond, and report new regulatory properties of this signaling system in Salmonella enterica serovar Typhimurium. Microarray data show that the Rcs system normally functions as a positive regulator of SPI-2 and other genes important for growth of Salmonella in macrophages, although when highly activated, the system completely represses the SPI-1/SPI-2 virulence, flagellar, and fimbrial biogenesis pathways. The auxilliary protein RcsA, which works with RcsB to positively regulate colanic acid and other target genes, not only stimulates but also antagonizes the positive regulation of many genes in the igaA mutant. We show that RcsB represses motility through the 'RcsB box' in the promoter region of the master operon flhDC, and that RcsA is not required for this regulation. Curiously, RcsB selectively stimulates expression of the flagellar Type 3 secretion genes fliPQR; an RcsAB box located downstream of fliR influences this regulation. We show that excess colanic acid impairs swimming and inhibits swarming motility, consistent with the inverse regulation of the two pathways by the Rcs system. The work was published in Journal of Bacteriology: Wang Q, Zhao Y, McClelland M, Harshey RM.
