FIG. 7.
Motility phenotypes of sirA ortholog mutants of various species. (A) Pseudomonas fluorescens in 0.28% T agar at 22°C. The wild-type CHAO is on the left and the gacA (sirA) mutant CHA89 is on the right. (B) Pseudomonas aeruginosa in 0.28% TSG agar at 37°C. The wild-type PAO1 is on the left and the gacA (sirA) mutant PAO6281 is on the right. (C) Vibrio cholerae in 0.35% TS agar at 37°C. The wild-type O395 is on the left and the varA (sirA) mutant SW33S is on the right.
