Fig. 4From: Prunus persica plant endogenous peptides PpPep1 and PpPep2 cause PTI-like transcriptome reprogramming in peach and enhance resistance to Xanthomonas arboricola pv. pruniHierarchical clustering analysis using Ward’s method and Euclidean distance of genes with differential expression (adj. p < 0.01, |log2FC| > 1.0) in at least one comparison: P1t1 vs. t0, P2t1 vs. t0, P1t24 vs. t1, P2t24 vs. t1, P1t48 vs. t24, and P2t48 vs. t24. P1: treatment with PpPep1; P2: treatment with PpPep2; time points: t0, t1, t24, and t48 for non-treated, and 1 h, 24 h and 48 h treatments, respectively. The dash corresponds to vs.. The color scale, red to blue, represents highly positive to highly negative log2FC, white corresponding to 0. Clustering into 14 partitions is shown on the leftBack to article page
