| Outline of Final Research Achievements |
In the present study, we try to develop a technology for flower color-alteration using flower petals-specific simultaneous controls of flavonoids and carotenoids biosynthesis pathway.
Transgenic plants overexpressing of each biosynthesis pathway genes of two plant pigments were produced in some model plants. In the transgenic plants of Tobacco and Torenia, flavonoids and carotenoids pigments were accumulated in these flower tissues and leaves, and the color of the flower and leaf were changed.
A newly developed method, a subtractive tissue-specific RNAi expression method were used for flower petals-specific gene expression in some model plants. As a result, flower color-specific alteration were observed in Tobacco plants, but on the other hand, color-changing of flower petals and leaves were observed in Lotus japonicus and Torenia.
