Characteristics of dihydroflavonol 4-reductase gene promoters from different leaf colored Malus crabapple cultivars.

ABSTRACT: Anthocyanins are secondary metabolites in land plants that contribute to the colors of leaves and flowers, and are nutritionally valuable components of the human diet. The DFR gene plays an important role in the anthocyanin biosynthetic pathway. In this study, we investigated the regulation of DFR expression and in different Malus crabapple cultivars that show distinct patterns of leaf coloration, and how it influences leaf anthocyanin accumulation and coloration. Specifically, we studied the ever-red leaved cultivar 'Royalty', the ever-green leaved cultivar 'Flame' and the spring-red leaved cultivar 'Radiant'. RT-PCR analysis showed that the expression of McDFR1 correlated with the expression of a MYB transcription factor, McMYB10, and with anthocyanin a
