Abstract
ABSTRACT The marine bacterium Vibrio alginolyticus has a single polar flagellum. Formation of that flagellum is regulated positively and negatively by FlhF and by FlhG, respectively. The ΔflhF mutant makes no flagellum, whereas the ΔflhFG double-deletion mutant usually lacks a flagellum. However, the ΔflhFG mutant occasionally reverts to become motile by forming peritrichous flagella. We have isolated a suppressor pseudorevertant from the ΔflhFG strain (ΔflhFG-sup). The suppressor strain forms peritrichous flagella in the majority of cells. We identified candidate suppressor mutations by comparing the genome sequence of the parental strain, VIO5, with the genome...
