Panel a: Hierarchical cluster analysis (HCA) of all samples against small RNA-seq features. HC has been performed with normalized and log-transformed data, using 1-Pearson correlation as distance measure and Complete Linkage as linkage method. Colors in the heatmap, as indicated in the color key, represent miRNAs expression level, log-transformed. Panel b: Principal component analysis (PCA) of all 18 samples in the small RNA-seq dataset. The X-axis represents the first components and the Y-axis the second component. Each replicate of the same sample is associated with the same color. Blue ovals enclose NGC samples, red ovals enclose grafted samples (M and P). Sample names: M = Mgt 101–14; P = 1103 Paulsen; NGC = not grafted control; T1 = veraison; T2 = maturity (PDF 388 kb)
