Resistant and susceptible phenotypes used in this study and their symptoms after PWN inoculation. (A) Vertical resin ducts in the cross section of the stem for resistant and susceptible phenotypes; the bar is 100 μm. (B) Difference in the parameters of the resin ducts between resistant and susceptible phenotypes in which resistant phenotypes had a larger AC size (resin duct size), AC area (resin duct area) and AC freq (resin duct frequency) than the susceptible phenotype (AC size comparison: n = 30, p = 0.001; AC area comparison: n = 30, p = 0.003; AC freq comparison: n = 30, p = 0.009). The mean + SE is represented by each bar. Different letters “a” and “b” on top of bars indicate significant differences (t-test, α = 0.05). (C) The materials used for transcriptome sequencing and each treatment contained three biological replicates. R: resin canal; X: xylem; P: pith; nX: new xylem.
