Fig. 3From: Comparative transcriptome analysis of Alpinia oxyphylla Miq. reveals tissue-specific expression of flavonoid biosynthesis genesCluster analysis of DEGs (a) Heat-map showing the expression of DEGs using RNA-seq data derived from mean value of three replicates of each sample based on log 2 (FPKM) values. Color code indicates expression levels. Similarity between samples and unigenes with hierarchical clustering is shown above and on the left of the heatmap, respectively. (b) Cluster analysis of all DEGs. The y-axis in each graph represents the mean-centered log2 (FPKM+ 1) value. Expression of a single gene is plotted in gray, while the mean expression of the genes in each cluster is plotted in blueBack to article page
