Mycelial growth assay of P hytophthora cactorum scr96‐silenced transformants under the oxidative stress condition. (a) Assay of mycelial growth of the wild‐type (WT), transformation control (GFP1) and scr96‐silenced transformants (S10 and S21 shown here) on Plich's agar medium only or supplemented with 2, 4 or 6 mm H₂O ₂. (b) Rates of growth inhibition were calculated for each treatment relative to growth on Plich's medium only. Colony diameters were measured in each independent biological experiment after 5 days of growth. Three independent biological experiments were performed with three replicates each time. Error bars represent the standard errors and asterisks indicate significant differences between the scr96‐silenced transformants and the WT (**P < 0.01).
