Ectopic CsLOB1 expression in citrus restores Xcc306ΔpthA4 canker symptoms. (A) Transgenic plant leaves were inoculated with Xcc306ΔpthA4 at 5 × 108 colony‐forming units (cfu)/mL, and then with 20 μL of dexamethasone (DEX, 100 μm) or mock solution at 24 h after bacterial inoculation. The photograph was taken at 7 days post‐inoculation. (B) Overexpression of CsLOB1 promotes the growth of Xcc306ΔpthA4. Leaves were inoculated with Xcc306ΔpthA4 at a concentration of 5 × 105 cfu/mL. The bacterial population was measured at the time points indicated. Error bar indicates the standard deviation for two replicates.
