Effects of PthXo1 translocation on Xoo virulence. a–d Comparisons of the Xoo virulence on the WT plants and OsIMPα1b-edited (OsIMPα1b-ED) mutants. PthXo1 translocation at 9 h post-inoculation (hpi) (a), expression of the PthXo1-targeted OsSWEET11 gene at 24 hpi (b), in planta bacterial populations at 0 and 72 hpi (c), and disease severity at 14 days post-inoculation (dpi) (d) were determined correspondingly. The data shown are mean values ± SDs (n = 3). The P values are from two-sided unpaired Student’s t tests (P < 0.01). e Fragments of Xoo-inoculated leaves imaged at 10 dpi. The leaf images are representative of 30 leaves of 15 plants tested in 3 experimental replications per genotype (WT, OsIMPα1b-ED#6, or OsIMPα1b-ED#17)
