Sliding motility in X. citri subsp. citri strains. ahrpB showed an increase in motility that could be restored to wild-type levels by the introduction of a plasmid containing the intact hrpB gene. b Measurements of the diameters of cell spread on plates. Cells were inoculated from bacterial cultures at exponential stage onto SB plates that were supplemented with 0.50 % agar. The assays were photographed and measured after 48 h of incubation at 28 °C. Abbreviations: wt-p53, wild-type strain 306 with empty vector pUFR053; ∆hrpB, hrpB mutant; and ∆hrpB-p53hrpB, complemented hrpB mutant. Values are expressed as the means ± standard deviations of three independent experiments. Different letters indicate significantly different p-values (p ≤ 0.05) in Tukey’s tests
