Figure 2. Effect of exogenous chemical treatments (SA, MeJA, or COR) on the flg22-triggered oxidative burst.
(A-C) Arabidopsis seedlings were pre-incubated with various concentrations of chemicals for the indicated time periods (0 and 24 h) before the start of ROS measurements. Flg22 (1 µM) was added at zero time. Error bars represent the SD of five independent samples (n = 10) and similar results were obtained in three independent experiments.
