Effect of DPI and of H₂O₂ generated by GOG on SA accumulation. Cells were treated with 50 nm β-megaspermin (beta), 10 μm DPI (DPI), or both (beta+DPI), or with 5 units/mL Glc oxidase and 5 mm Glc (GOG), 50 nm β-megaspermin and 10 μm DPI and 5 units/mL Glc oxidase and 5 mm Glc (beta+DPI+GOG). For the latter treatment, GOG was added at the same time as the elicitor (0), 0.75 h later (0.75), or 3 h later (3). SA was measured after 14 h of incubation. C, Control cells. Bars represent the means ± sd of two independent experiments.
