Fig. 5
A detailed part of flavonoid metabolic subnetwork showing the subset of nodes or metabolites that constitute the process. Enzyme names, unigene names and expression patterns are indicated at the side of each step. The expression pattern of each unigene is shown on two grids, with the left one representing the FPKM value of S1, and the right one representing the relative log2(S3/S1). The grids with seven different colors show the absolute expression magnitude of S1, withV the FPKM values 0–1, 1–2, 2–4, 4–8, 8–16, 16–32, and 32–64 represented by different scale levels 1–7, respectively. CHS: chalcone synthase; CHI: chalcone isomerase; F3H: flavanone 3-hydroxylase; F3′H: flavonoid 3′-hydroxylase; F3′5′H: flavonoid 3′5′-hydroxylase; FLS: flavonol synthase; UF3GT: flavonol 3-O-glucosyltransferase; DFR: dihydroflavonol 4-reductase; ANS: anthocyanidin synthase; UA3GT: anthocyanidin 3-O-glucosyltransferase
