Figure 3. The effect of SA and COR in the flg22-triggered oxidative burst is dependent on NPR1 and COI1, respectively.

(A–D) Effect of pretreatment with SA (100 µM) or COR (0.5 µM) for 24 h on the flg22-triggered oxidative burst in mutant [pad4 (A), npr1 (B), jar1 (C), coi1 (D)] and wild-type Columbia seedlings. 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.
