Figure 1From: Allelic variation of soybean flower color gene W4 encoding dihydroflavonol 4-reductase 2Schematic diagram of the anthocyanin and flavonol biosynthetic pathways. Enzyme names are abbreviated as follow: chalcone synthase (CHS), chalcone isomerase (CHI), flavanone 3-hydroxylase (F3H), dihydroflavonol 4-reductase (DFR), flavonoid 3′-hydroxylase (F3′H), flavonoid 3′5′-hydroxylase (F3′5′H), flavonol synthase (FLS), leucoanthocyanidin dioxygenase (LDOX). Soybean flower color genes encoding the enzymes are in italic font.Back to article page
