| 内容記述 | Evergreen azaleas are one of the representative ornamental woody plants. Cultivated varieties have been derived from natural and artificial hybridization and selection among evergreen species belonging to subgenus Tsutsusi in the genus Rhododendron. The flower colors of cultivated varieties are mainly variations of white, pink, red, or purple. However, no yellow-flowered cultivar of evergreen azaleas has been produced till date. In a previous report, we compared the concentration and composition of carotenoids and the expression patterns of carotenoid biosynthesis and cleavage genes during petal development in a yellow-flowered deciduous azalea (Rhododendron japonicum f. flavum), a white-flowered evergreen azalea (‘Miyamasatsuki’), and their progeny, to determine the factors that cause discoloration as the petals of the progeny develop. The progeny has a relatively high expression of carotenoid biosynthetic genes inherited from R. japonicum f. flavum. Carotenoid degradation in the petals of the progeny was mediated by a high CCD4 gene expression inherited from white-flowered evergreen azalea. Thus, inactivation of CCD4 gene during petal development is useful to avoid discoloration of petals in the progenies. Heavy-ion beam irradiation is one of the useful methods for inactivation of target genes. The present study was conducted to clarify an efficient dose of heavy-ion beam irradiation for azalea seeds. | |||||
