Simplified diagram of biosynthetic pathways flavonoids in A. majus. The 4’-O-glucosylation of chalcone by cytosolic 4’CGT followed by oxidative cyclization by vacuolar AS is the biochemical basis of aurone 6-O-glucoside biosynthesis in vivo. Chalcone is the branching point of aurone pathway from the flavone/anthocyanin pathway. CHS, chalcone synthase; CHI, chalcone isomerase; F3H, flavanone 3-hydroxylase; DFR, dihydroflavonol 4-reductase; ANS; anthocyanidin synthase; 3GT, anthocyanin 3-O-glucosyltransferase; FNS, flavone synthase; AS, aureusidin synthase; 4’CGT, chalcone 4’-O-glucosyltransferase; THC, tetrahydroxychalcone; PHC, pentahydroxychalcone. Red arrows, the aurone biosynthetic pathway in vivo reported in this study
