Additional file 3 of Prunus persica plant endogenous peptides PpPep1 and PpPep2 cause PTI-like transcriptome reprogramming in peach and enhance resistance to Xanthomonas arboricola pv. pruni

Additional file 3. Interactive principal component analysis (PCA) of regularized–logarithm normalized expression data from the 500 genes showing the highest variance (DESeq2 1.20.0 package [60]) conducted in R [63] using scatter plot 3d library [73]. Three principal components, PC1, PC2 and PC3, with Eigenvalues above 1 explained 83.84%, 7.04% and 2.81% of the overall variability, respectively. The peptide treatments are shown in different colors: tan, time zero (t0); turquoise, 1 h PpPep1 (P1t1); light green, 1 h PpPep2 (P2t1); blue, 24 h PpPep1 (P1t24); pink, 24 h PpPep2 (P2t24); orange, 48 h PpPep1 (P1t48); yellow, 48 h PpPep2 (P2t48). Three biological replicates per sample are shown.
