| Outline of Final Research Achievements |
To evaluate anthocyanin pigmentation, we investigated pigment composition, pH value in the petal and anthocyanin synthesis related gene expression. In azalea flower, color variation can be explained by anthocyanidin and co-pigment effect of flavonol, and high pH value of petal showed bluer color tendency. Anthocyanin pigmentation of azalea petal may be regulated by a later step of glycosylation step because white flower can produce flavonol and proanthocyanidin pigment and was expressed glycosylation related genes as well as anthocyanin pigmented flower. In Japanese radish, several structural genes of anthocyanin pathway is not expressed in white root, suggesting that MYB transcriptional factor is related to pigmentation.
