flagellar motility
Research ArticleRapid Accumulation of Motility-Activating Mutations in Resting Liquid Culture of Escherichia coliThe ability to tune gene expression in times of need outside preordained regulatory networks is an essential evolutionary process that allows organisms to survive and compete. Here, we show that upon overnight incubation in liquid medium without shaking, populations of largely nonmotile Escherichia coli bacteria can rapidly accumulate mutants that have constitutive...
- Meeting PresentationA Critical Region in the FlaA Flagellin Facilitates Filament Formation of the Vibrio cholerae Flagellum
V. cholerae causes the severe diarrheal disease cholera. Its ability to swim is mediated by rotation of a polar flagellum, and this motility is integral to its ability to cause disease and persist in the environment. The current studies illuminate how one specific flagellin (FlaA) within a multiflagellin structure mediates formation of the flagellar filament, thus...
