EpiBL perception inhibits PTI signaling. (A) Effect of pretreatment with 1 μM epiBL for the indicated time on ROS triggered by 50 nM flg22 in Col-0 leaf discs. Total ROS production during 40 min of treatment is expressed as percentage of flg22-treated Col-0 without epiBL treatment. Values are mean ± SE (n = 20). (B). Quantitative RT-PCR of FRK1 and At2g17740 gene expression in 2-wk-old Col-0 seedlings treated with 1 μM flg22 and/or 1 μM epiBL for the indicated time. Transcript levels are normalized to the U-box gene and are presented as relative to time 0. Values are mean ± SD (n = 3). (C) Seedling growth inhibition induced by increasing concentrations of flg22 in absence (◇) or presence (◆) of 1 μM epiBL. Values are mean ± SD (n = 12; **P < 0.01 and ***P < 0.001). Similar results were observed in at least two independent experiments.
