BIK1 is required for Pep1-induced defenses. (A) bik1 is compromised in Pep1-induced oxidative burst. Relative luminescence units indicate relative amounts of H2O2 production in leaf strips treated with 1 μM Pep1 at the indicated times. Different letters indicate significant difference (mean ± SD; n ≥ 4; P < 0.01, Student’s test; nine biological repeats). (B) bik1 is severely compromised to Pep1-induced callose deposition (mean + SD; n ≥ 15; P < 0.01, Student's t test; four biological repeats). (C and D) Pep1 pretreatment was unable to protect bik1 from B. cinerea infection. Leaves were infiltrated with Pep1 18 h before inoculation with B. cinerea. Disease lesion was measured 2 d later (mean + SD; n ≥ 7; P < 0.01, Student's t test; two biological repeats). P value is given above the bars.
