Fig. 6From: Discovery of genes involved in anthocyanin biosynthesis from the rind and pith of three sugarcane varieties using integrated metabolic profiling and RNA-seq analysisHierarchical clustering of 50 flavonoid and anthocyanin biosynthesis genes. The scale bar denotes the log2 (FPKM + 1)/ (mean expression levels across the three treatment groups). The color represents relative gene expression levels. While the horizontal direction shows the sample names, the vertical direction shows the names of genes involved in the biosynthesis of flavonoids and anthocyaninsBack to article page
