A few carnation cultivars are known to display a peculiar dusky color supposedly caused by anthocyanic vacuolar inclusions (AVIs). The hereditary pattern suggests that the peculiar color is controlled by a single recessive factor tightly linked with existence of AVIs containing non-acylated anthocyanins. To diversify the peculiar color carnation, we produced a bluish purple line displaying a highly novel metallic appearance by crossbreeding. By subjecting the line to ion-beam irradiation, we generated metallic reddish purple, metallic crimson and metallic red lines. All four metallic lines did not have transcripts for anthocyanin malyltransferase. In contrast to the dusky color types, metallic lines have highly condensed AVIs and water-clear vacuolar sap in the petal adaxial epidermal cells. We demonstrated that (1) a factor generating the AVIs is inactivated anthocyanin malyltransferase gene, (2) AVIs in water-clear vacuolar sap in the adaxial epidermal cells generate the novel metallic appearance, and (3) ion beam breeding is a useful tool for increasing metallic colors by changing anthocyanin structure and the level of AVIs.

Comparative analysis of floral pigmentation between wild-type and white-flowered varieties of ${it Cyclamen graecum}$

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.

Red-purple flower due to delphinidin 3,5-diglucosides, a novel pigment for ${it Cyclamen}$ spp., generated by ion-beam irradiation

Fragrant cyclamen cultivar (${it C. persicum}$ $$times$$ ${it C. purpurascens}$), that bloomed purple flower containing malvidin 3,5-diglucoside as the major anthocyanin, was irradiated with a 320-MeV carbon-ion beam at 0-16 Gy to increase flower color variation by mutation. Some of the M2 plants derived from self-pollination of M1 plants irradiated at 2 Gy were flower-color mutants that retained desirable flower shape, flower size, and leaf color. One of the mutants bloomed novel red-purple flowers, the major anthocyanin of which was delphinidin 3,5-diglucoside. Because the major anthocyanins in flowers of ${it Cyclamen}$ spp. were previously restricted to malvidin, peonidin, and cyanidin types, the generation of a cyclamen containing mostly the delphinidin-type anthocyanin is an important breakthrough in cyclamen breeding. We expect this mutant to become not only a commercial cultivar itself, but also a valuable genetic resource for cyclamen breeding.

One of the fragrant cyclamens, Kaori-no-mai, blooms purple flowers containing malvidin 3,5-diglucoside as the major anthocyanin. Here, we irradiated etiolated petioles of Kaori-no-mai with a 320-MeV carbon-ion beam to increase flower color variation by mutation. Some of the M2 plants derived from self-pollination of M1 plants were flower-color mutan. One of the mutants bloomed novel red-purple flowers, the major anthocyanin of which was delphinidin 3,5-diglucoside. The major anthocyanins in flowers of ${it Cyclamen }$ spp. were previously restricted to malvidin, peonidin, and cyanidin types, therefore, the generation of a cyclamen containing mostly the delphinidin-type anthocyanin is an important breakthrough in cyclamen breeding. We expect this mutant to become not only a commercial cultivar itself, but also a valuable genetic resource for cyclamen breeding.
