a, b Histochemical staining with DAB and NBT for O2− (a) and H2O2 (b) in situ accumulation, respectively, in WT, V#10, and MdWRKY75e transgenic lines (#1, #8, and #12) at 0 and 24 h of infection. c, d Levels of O2− (c) and H2O2 (d) in WT, V#10, and MdWRKY75e transgenic lines at 0 and 24 h of infection. WT: wild-type; V#12: empty vector; and MdWRKY75e#1, MdWRKY75e#8, and MdWRKY75e#12: MdWRKY75e transgenic lines
