| Outline of Final Research Achievements |
Flower color pattern is important not only for induction of insects but also for enhanced value of floricultural plants. This study was attempted to reveal the molecular mechanism by transcriptome and metabolic analyses using Japanese gentian and Cymbidium. In Cymbidium, flavonoid 3’-hydrocylase (F3’H) and transcription factor CyMYB1 were responsible for the pigmentation of labellum organ. On the other hand, strip flower color of Japanese gentian was degraded chalcone synthase (CHS) mRNA in white-color lobe organs. These results indicated different molecular mechanism of flower pigmentation pattern among plant species.
