Figure 1From: How to perform RT-qPCR accurately in plant species? A case study on flower colour gene expression in an azalea (Rhododendron simsii hybrids) mapping populationProposed flavonoid biosynthesis pathway in azalea. The pathway only leads to the production of cyanidin pigments and is redrafted after [8, 34]. CHS: chalcone synthase; CHI: chalcone isomerase; F3H: flavanone 3-hydroxylase; F3'H: flavonoid 3'-hydroxylase; DFR: dihydroflavonol 4-reductase; ANS: anthocyanidin synthase; OMT: O-methyltransferase; UFGT: UDP-glucose:flavonoid 3-O-glucosyltransferase; RT: rhamnosyl transferase; FLS: flavonol synthase.Back to article page
