Heatmap depicting the tissue-specific expression patterns of DEGs probably involved in flavonoid biosynthesis. The heatmap was conducted from the standardized FPKM profiles of the unigenes. Rf, Sf, Lf, Ff, and Faf represent root, stem, leaf, inflorescence, and infructescence, respectively. The unigene marked using black ‘#’ represent DEG encoding CHS. The unigene marked using red ‘#’ represent DEG encoding CHI. The unigene marked using blue ‘*’ represent DEG encoding FLS. The unigene marked using green ‘*’ represent DEG that encode ANS. The unigene marked using red ‘*’ represent DEG that encode GT
