The proposed core pathways responsible for flavonoid biosynthesis in Z. bungeana. The full name of the enzymes (violet color font) are: PAL, phenylalanine ammonia-lyase; C4H, cinnamate-4-hydroxylase; 4CL, coumaroyl-CoA ligase; CHS, chalcone synthase; CHI, chalcone isomerase; FNSII, flavone synthase II; F3H, flavanone-3-hydroxylase; DFR, dihydroflavonol reductase; ANS, anthocyanidin synthase; FLS, flavonol synthase; CYP75A, flavonoid 3′,5′-hydroxylase; CYP75B1, flavonoid 3′-monooxygenase; UGT, flavonoid O-glycosyltransferase; RT, UDP-rhamnose synthase; HT, hydroxylase; MT, flavonoid O-methyltransferase. The candidate genes encoding the enzymes involved in flavonoid biosynthesis are highlighted by red color and italic font, and the identified genes in them are highlighted by bolded font. The identified chemical components are highlighted by bold font and with black text boxes
