Expression profiling of apple anthocyanin genes.
(a) Data from qPCR analysis of the apple anthocyanin biosynthetic genes in the cortex, skin and leaf of the apple cultivars ‘Red Field’ and Pacific RoseTM. CHS, chalcone synthase; CHI, chalcone isomerase; F3H, flavanone 3β-hydroxylase; DFR, dihydroflavonol 4-reductase (denoted as DFR1 in the text); LDOX, leucoanthocyanidin dioxygenase; UFGT, uridine diphosphate (UDP)-glucose:flavonoid 3-O-glycosyltransferase. Samples referred to on the x axis: (1) 40 days after full bloom (DAFB), (2) 67 DAFB, (3) 102 DAFB, (4) 130 DAFB, (5) 146 DAFB, (6) ‘Red Field’ leaf and (7) Pacific RoseTM leaf. Error bars are SE for three replicate reactions.
(b) Fruit development series and leaves of ‘Red Field’ and Pacific RoseTM. Numbering from 1 to 7 as for (a).
