Fig. 10From: Integrative analysis of transcriptome and metabolome reveals flavonoid biosynthesis regulation in Rhododendron pulchrum petalsWGCNA of genes in three different color petals of R.pulchrum Sweet. a Hierarchical clustering tree (cluster dendrogram) results showed 12 expression modules, labeled with different colors. b Module–sample association. Each row corresponds to a module, labeled with a color as in (a). The number of genes in each module is indicated on the leftBack to article page
