| Outline of Final Research Achievements |
We analyzed changes of characters in association with the evolution of mycoheterotrophy by using pairs of mycoheterotrophs and its autotrophic sister species from several plant groups and estimated patterns and processes in the evolution of mycoheterotrophy. The results showed that communities of fungal partners change in the course of the evolution from autotrophy to mycoheterotrophy in plants and that convergence of fungal partners occurs in distantly related mycoheterotrophs. These results suggest that selection of fungal partners optimizing nutrition process of a plant acts as key innovation in the evolution of mycoheterotrophy.
