Pep1-induced callose and lignin deposition relies on PEPR1/2, BAK1/SERK4, BIK1/PBL1 and AGB1. (a and b) Pep1 induces callose and lignin depositions through PEPR1/2, BAK1/SERK4, and BIK1/PBL1. (c and d) PEPR2 plays a major role in the Pep1-induced lignin disposition. (e and f) Pep1, Pep2, but not Pep3 induce lignin disposition in root tips.(g-h) Pep1 induces callose and lignin deposition through AGB1. One-week-old plate-grown seedlings of indicated genotypes were treated with H2O or 1 μM Pep1 for 24 hours, followed by callose or lignin staining. Quantification data of callose and lignin in b, d, f, and h were indicated as means of intensity unit from each repeat. Significant differences were shown by different letters (Student’s t-test, n ≥ 8). The experiment was repeated three times with similar results. Bar = 200 μm.
