Canker disease tolerance assay of the wild type (WT) and the transgenic lines (TG4 and TG9). Disease index (A, E) and lesion area (B, F) of WT, TG9 (A-D) and TG4 (E-H) after inoculation with Xac. Comparison between TG9 and WT, TG4 and WT was done in different inoculation experiment. Asterisks show that the values are significantly different compared with the control (* for P < 0.05, ** for P < 0.01 and *** for P < 0.001). Representative photographs showing symptoms on the abaxial (C, G) and adaxial (D, H) sides of the leaves from WT/TG9 (C-D) and WT/TG4 (G-H). Selected inoculation sites of the leaves were zoomed in and shown below the corresponding photos.
