FIGURE 1.

Effect of AtPep1 and flg22 peptide on wild type seedlings and pepr1 mutants. Seedlings (5 days old) of Arabidopsis Col-0 WT (A) and pepr1 mutants (B) were incubated for 10 days in MS medium in the presence of AtPep1 (1 μm) or flg22 (1 μm) or in absence of elicitors. Growth was quantified by determining the total fresh weight per seedling and length of the longest root per seedling. The experiment was repeated three times with similar results. Shown are mean ± S.E. (fresh weight, n = 6; root length, n = 12). The means shown with the same letters were not significantly different based on the least significant difference test (p < 0.05). Representative seedlings were photographed.
