The effects of Peps on root hair development. (A) The growth phenotype of wild type root under Pep1-Pep8 treatment. Four-day-old WT plants were transplanted on half-strength Murashige and Skoog (MS) agar medium supplemented with or without 10 nM Pep1 to Pep8 for 48 h. Bars = 200 μm. (B, C) Statistics of the root hair number (B) and root hair length (C) as in (A). Data are means ± SD (n = 15 roots per treatment). Asterisks in (B, C) indicate statistically significant differences compared with the untreated control. (Tukey’s test; *p < 0.05, **p < 0.01).
