Vibrio cholerae is highly motile by the action of a single polar flagellum. The loss of motility reduces the infectivity of V. cholerae, demonstrating that motility is an important virulence factor. FlrC is the sigma-54-dependent positive regulator of flagellar genes. Recently, the genes VC2206 (flg...
ORGANISM(S): Vibrio cholerae 
Bacteria growing as surface-adherent biofilms are better able to withstand chemical and physical stresses than their unattached, planktonic counterparts. Using transcriptional profiling and quantitative PCR, we observed a previously uncharacterized gene, yjfO, to be upregulated during Escherichia co...

Here we demonstrate by experimental evolution and genetics the rapid and repeatable evolutionary re-wiring of regulatory pathways, where the cellular nitrogen regulatory system acquired the ability to “cross-talk” with the flagellar regulon. This rewiring restored flagella to aflagellate strains of ...

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...

This study examined the genes under the control of FlhDC and sigmaF in E. coli. Keywords: wild-type, deletion and overexepression strains Under defined steady-state growth condition, we used two different genetic approaches to alter the modulator concentration in cells; (1) moderately expressing Fl...

Gametogenesis and fertilization play crucial roles in malaria transmission. While male gametes are thought to be amongst the simplest eukaryotic cells and are proven targets of transmission blocking immunity, little is known about their molecular organization. For example, the pathways of energy met...
