| Outline of Final Research Achievements |
In plant-pollinator and plant-mycorrhiza mutualisms, diverse parasites are known to invade the mutual systems. We explored diversity, ecology and origin of these parasites, and examined the impact of the parasites on the mutualism. In Phyllanthaceae-Epicephala obligate pollination mutualism, the floral odor was different between male and female flowers, and parasitism of braconid wasps on pollinator wasp/seeds had a great impact on performance of the pollinator moths and the Phyllanthaceae plants. Mycoheterotrophic plants are parasites in mycorrhizal mutualisms, and pollinator and fungal partners of mycoheterotrophic plants such as Orchidaceae, Burmanniaceae and Triuridaceae were investigated. The mycoheterotrophic plant Gastrodia pubilabiata was revealed to be pollinated by drosophilid flies, whose larvae are parasites of fruit body of the mycorrhizal partner of the mycoheterotrophic plant.
