Fig. 2From: Integrated metabolome and transcriptome analyses of anthocyanin biosynthesis reveal key candidate genes involved in colour variation of Scutellaria baicalensis flowersMetabolome profiles of three different flowers of S. baicalensis. a. Classification of all identified metabolites. b. HCA of all identified metabolites. Horizontal refers to sample name, and vertical refers to metabolite information. The subclass names of metabolites are labeled on the left of HCA. The color indicates the standardized relative contents of metabolites using unit variance scaling by row. Red represents high content, and green represents low content. c. Numbers of differentially accumulated metabolites among different colours of flowersBack to article page
