The anthocyanin pigments biosynthesis pathway in onions showing how
the gene alleles that determine skin colour act at the enzyme level to determine
which pigments are produced. The enzymes are abbreviated as follows: CHS,
chalcone synthase; CHI, chalcone isomerase; F3H, flavanone 3-hydroxylase; F3'H,
flavonoid 3
-hydroxylase; DFR, dihydroflavonol 4-reductase; ANS, anthocyanidin
synthase; FLS, flavonol synthase; UFGT, UDP glucose-flavonoid 3-
o
-glucosyl
transferase (annotated from Kim
