| Outline of Final Research Achievements |
We obtained the comprehensive datasets of floral scent profiles for the genus Asarum (Aristolochiaceae), Phyllanthus (Phyllanthaceae), and Mitella (Saxifragaceae). Especially we found that the species of the genus Asarum have complex and diverse floral scent profiles; even closely related species had strikingly dissimilar scent profiles. We surveyed the pollination systems for some Asarum species that have diverse floral scent profiles, and found that the pollinators were different among species. We successfully cloned some floral scent-associated genes from these plants. We further obtained the signature of expected divergent selection during ecological speciation in at least three floral scent-associated genes in the genus Mitella.
