FIG. 2.
Swimming and swarming motility of the Rcs signaling pathway and regulatory mutants. (A) The motility of the indicated mutant strains on 0.3% swim or 0.6% swarm Eiken agar. Mutations introduced in the promoter region of flhD are indicated in parenthesis after pflhD. (B) The motility of the indicated mutant strains on 0.3% swim (white bars) or 0.6% swarm (gray bars) Eiken agar. Similar results were obtained with Bacto agar. The data are averages from three independent experiments conducted in triplicate. Error bars are standard deviations from the means. Plates in both panels were incubated at 37°C for 6 h.
