| Outline of Final Research Achievements |
Lily (Lilium spp.) is among the most important floricultural plants. Color and fragrance of flowers, and early flowering are their important traits. An Asiatic hybrid lily ‘Grand Cru’ developed big anthocyanin spots, a unique color pattern, on its tepals and it was clarified that novel transcription factor MYB18 regulated the big-spot development. Suppression of carotenoid accumulation is crucial to create white flowers: Carotenoid cleavage dioxygenase 4 (CCD4) should be the major factor in Asiatic hybrid lilies but other mechanisms might be responsible in Oriental and Longiflorum hybrid lilies. In addition, transcription factors FLOWERING LOCUS T (FT) and ODORANT1 were characterized, which might regulate flowering and benzenoid volatile emission, respectively, in lilies.
