In the published article, in Figures 1 and 2 as well as Supplementary Figures 1, 2 and 3 the picture legend on the right side of the figures shows an example of the % of damage in the leaves. We have updated the independent scale of diseased leaves for Figures 1 and 2 and we have deleted the scale legend in the Supplementary Figures 1, 2 and 3. The corrected legend appears now in the updated Figures 1 and 2 below, and in the Supplementary Material in the original files.
Figure 1 Pep1 and Systemin induced-resistance assays against Plectosphaerella cucumerina in Arabidopsis plants. Infection levels 5 days after inoculation quantified by a disease rating in trypan blue stained leaves, measured as a percentage of the infected leaf surface. Arabidopsis Col-0 plants were treated with increasing concentrations of Pep1 or Systemin (0.1, 1, 10, and 20 nM) 24 h before infection with 1 μl droplets of 5 × 10E3 spores/ml of P. cucumerina BMM. ß-amino butyric acid (BABA) at 1 ppm was used as a positive control. Colors mean % of diseased leaves in a scale (0 = healthy leaves; 1 = leaves with less than 25% of diseased surface; 2 = leaves with 25–50%; 3 = leaves with 50–75% of the diseased surface, 4 = leaves with more than 75% of the surface diseased). Different letters indicate statistically significant differences (ANOVA, Fisher’s Least Significant Difference (LSD) test; P < 0.05, n = 24). The experiment had 6 plants per treatment and was repeated at least three times with similar results.
Figure 2 HypSys peptides induced-resistance assays against Plectosphaerella cucumerina in Arabidopsis plants. Infection levels 5 days after inoculation quantified by a disease rating in trypan blue stained leaves, measured as a percentage of the infected leaf surface. Arabidopsis Col-0 plants were treated with increasing concentrations of HypSysI, HypSysII, and HypSysII (0.1, 1, 10, and 20 nM) 24 h before infection with 1 μl droplets of 5 × 10E3 spores/ml of P. cucumerina BMM. ß-amino butyric acid (BABA) at 1 ppm was used as a positive control. Colors mean % of diseased leaves in a scale (0 = healthy leaves; 1 = leaves with less than 25% of diseased surface; 2 = leaves with 25–50%; 3 = leaves with 50–75% of the diseased surface, 4 = leaves with more than 75% of the surface diseased). Different letters indicate statistically significant differences (ANOVA, Fisher’s Least Significant Difference (LSD) test; P < 0.05, n = 24). The experiment had 6 plants per treatment and was repeated at least three times with similar results.
