Citrus canker disease development in Xanthomonas citri inoculated Duncan grapefruit plants. a Representative leaves from ten replicates to show the development of canker symptoms on leaves inoculated with Xanthomonas citri subsp. citri wild type (Wt) strain 306 and its ∆rpfF mutant (M) with bacterial solutions (5 × 10⁶ CFU/ml) by infiltration using needleless syringes and photographed at different days post inoculation (DPI). b Bacterial population growth in in Duncan grapefruit leaves inoculated with bacteria (5 × 10⁶ CFU/ml) at different days post inoculation. Error bars represent standard deviation. All the experiments were repeated three times
