Figure 1From: Loss-of-function mutations affecting a specific Glycine max R2R3 MYB transcription factor result in brown hilum and brown seed coatsSimplified representation of the biosynthetic pathway of anthocyanins. Enzymes are indicated by bold text, intermediates are indicated by plain text, and gene locus designations are in italics. Enzymes are abbreviated as follows: 4-coumarate: CoA ligase (4CL), Anthocyanin Reductase (ANR), Chalcone Synthase (CHS, Inhibitor locus), Chalcone Isomerase (CHI), cinnamic acid 4-hydroxylase (C4H), Dihydroxyflavone Reductase (DFR), Flavanone 3-Hydroxylase (F3H, Wp), Flavonoid 5' 3' Hydroxylase (F3'5'H, W1), Flavonoid 3' Hydroxylase (F3'H, Tawny) Leucoanthocyanidin Reductase (LAR), Phenylalanine Ammonia-Lyase (PAL). The chemical structures to the right of the pathway correspond to eriodictyol, dihydroquercetin, leucocyanidin, cyanidin, and cyanidin-3-glucoside (from top to bottom, respectively).Back to article page
