Sensitivity of the X. citri wild-type, ecnA::Tn5, and ecnA::Tn5_c strains to hydrogen peroxide (H₂O₂). (A) Bacterial quantification before and after H₂O₂ stress. (B) Relative expression of ecnA and ecnB in X. citri after H₂O₂ stress compared to cells without stress. The transcript abundance was determined by RT-qPCR. Data are shown as the means of two independent biological experiments and three technical replicates. Error bars indicate the standard deviation of the mean. 16S rRNA was used as an endogenous control. *, significant difference at P < 0.05; **, significant difference at P < 0.01.
