In S. typhimurium, 27 fla genes responsible for formation of flagella have been identified and assigned to three regions on the genetic map, termed fla regions I to III. By genetic analysis of 1984 non-flagellate mutants obtained from a phase-1 stable strain of S. typhimurium, SJW1103, three additional fla genes were identified; one, termed flaW, was assigned to fla region I and the other two, termed flaV and flaX, to fla region III. By intergeneric complementation test, the flaW, flaV and flaX genes were shown to be functionally homologous with flaS, flbC and flaP of Escherichia coli, respectively. Electron microscopy showed that flaW and flaV mutants carried hook-basal body structures.
