XrvB plays positive impacts on cell motility and stress tolerances. a Cell motility test of Xoc strains. Two microliters of Xoc culture suspension (OD600 of 1.0) were stabbed into ‘swimming’ plates or inoculated onto “swarming” plates followed by incubation for 4 days. Data shown are the mean ± SD (n = 15). Significance was determined by ANOVA and Dunnett's post hoc test for comparison to the wild type. *P < 0.05; n.s., not significant. b Stress tolerance test of Xoc strains. Survival experiments were performed by subculturing strains overnight on fresh NA agar plates supplemented with different concentrations of SDS (i), phenol (ii), NaCl (iii), and CuSO4 (iv). The surviving bacterial colonies on the plates were counted after incubation for 3 days. Values given are the means ± SD (n = 3 biological repeats)
