(A) Promoter activity of AbLOB1 and CsLOB1 induced by PthA4 in tobacco. (B) GUS staining assay in tobacco leaves. Agrobacteria containing pAbLOB1:GUS or pCsLOB1:GUS mixed with 35S: pthA4 or empty vector were infiltrated into tobacco leaves. Samples were collected at 2 days (Fig 7A and 7B). (C) Transient GUS activity related to pAbLOB1 and pCsLOB1 promoters after inoculation with Xcc or Xcc306ΔpthA4 in sweet orange. Samples were collected for further analysis at 4 days post inoculation. (D) GUS staining assay of sweet orange leaves upon ectopic expression of pAbLOB1:GUS or pCsLOB1:GUS post inoculation with Xcc or Xcc306ΔpthA4. Error bars indicate standard deviation of three independent replicates. Different letters above the bars represent significant differences (P < 0.05) in Duncan’s multiple range test.
