Fig. 2From: Integrated metabolome and transcriptome analysis of the anthocyanin biosynthetic pathway in relation to color mutation in miniature rosesa Principal component analysis based on FPKM data; b Clustered heatmap based on the 190 metabolites between the flower samples. The color scale (from red to green) represents normalized metabolite contents using the row Z-score. DH, Neptune King metabolites; DS, Queen metabolitesBack to article page
