The flower colour of ${it Cyclamen graecum}$ gra6 (wild-type) is pink-purple in the flower. On the other hand, flowers of ${it C. graecum}$ gra50 (white-flowered variant) exhibit a white colour in its flower. In this study, the relationship between floral pigmentation and expression of several anthocyanin biosynthesis genes was investigated in ${it C. graecum}$ gra6 and gra50. The pigments in the flower consist mainly of malvidin 3,5-diglucoside in gra6. White-flowered ${it C. graecum}$ gra50 possessed lower amounts of anthocyanins, but higher amounts of flavonols compared to gra6. Gene expression analysis demonstrated that expression of the dihydroflavonol 4-reductase gene 2 (${it CgraDFR2}$) was lower in gra50 compared with gra6, whereas the expression of other key genes did not differ greatly. These results suggest that the white-flowered variant of gra50 may result from a defect in expression of the ${it CgraDFR2}$ gene.
