Fig 5. The B. dolosa fixLJ deletion mutant is less motile.
(A) B. dolosa strain AU0158, its fixLJ deletion mutant, and the fixLJ deletion mutant complemented with fixLJ under the control of its own promoter or empty vector (EV) were plated on low-density (0.3%) LB agar and swimming distance was measured after incubation for 48 hours. *P<0.05 by 1-way ANOVA with Tukey’s multiple comparison test. (B) The B. dolosa fixLJ -deletion mutant complemented with fixLJ under the control of a rhamnose-inducible promoter or empty vector grown in the presence of glucose (0.4%, which represses fixLJ expression) or rhamnose (0.4%). *P<0.05 by 1-way ANOVA with Tukey’s multiple comparison test relative to the complemented strain (ΔfixLJ + fixLJ) grown in rhamnose-containing media. For all panels, bars represent mean measurements of 3–4 replicates and error bars represent one standard deviation (representative of three independent experiments).
