| Outline of Final Research Achievements |
The relation between inflorescence architecture and LEAFY (LFY)-like gene was examined by using two Tricyrtis spp. (T. hirta and T. formosana) showing different inflorescence architectures. No differences in the structure, function and expression pattern in young plants of the LFY-like genes were observed between these species. Further expression analysis of the LFY-like genes is necessary at the flowering stage. Transgenic plants ectopically expressing the LFY-like genes showed dwarf and early-flowering phenotypes, indicating a possibility of breeding of ornamental plants by genetic transformation with the LFY-like genes. TFL1-like genes, which have been reported to be expressed antagonistically with LFY-like genes, were then isolated from T. hirta and T. formosana. However, no difference in the estimated amino acid sequence of the TFL1-like genes was observed between these species.
