Growth rates of <i>X</i>. <i>fastidiosa</i> mutant strains used in this study.

Growth rate was calculated from the growth curve at the exponential growth phase (2 to 6 days post inoculation). WT is highlighted in blue, and the dashed blue line indicates the mean value of growth rate for the WT. Data represent means and standard errors. Different letters on top of bars indicate significant difference as analyzed by ANOVA followed by Tukey’s HSD multiple comparisons of means (P (TIF)
