Functional Analysis of Genes GlaDFR1 and GlaDFR2 Encoding Dihydroflavonol 4-Reductase (DFR) in Gentiana lutea L. Var. Aurantiaca (M. Laínz) M. Laínz

Figure 1

The anthocyanin biosynthesis in the flavonoid metabolic pathway in plants. Dashed lines indicate that the anthocyanidins are catalyzed by anthocyanidin glycosyltransferase (GT) and are converted into anthocyanins in the cytoplasm and vacuoles. ANS: anthocyanidin synthase; CHI: chalcone isomerase; CHS: chalcone synthase; DFR: dihydroflavonol 4-reductase; F3H: flavanone 3-hydroxylase; F3H: flavonoid 3-hydroxlase; F35H: flavonoid 3,5-hydroxlase; FLS: flavonol synthase; FSII: flavone synthase.
