<p>(A) Effect of pretreatment with SA (100 µM) or COR (0.5 µM) for 24 h on the flg22- triggered oxidative burst in <i>cim6</i> and wild-type Columbia seedlings. Flg22 (1 µM) was added at zero time. (B) COR did not suppress flg22-induced ROS generation when applied simultaneously with SA. Eight-day-old seedlings were pre incubated with SA (100 µM), COR (0.5 µM), or SA plus COR for 24 h. 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 at least two independent experiments.</p
