| Research Abstract |
We hypothesize that epiphyte evolution is possible to be related with mycorrhizal fungi. To clarify the hypothesis, we performed (1) molecular phylogeny of plants and their fungi using epiphyte and its closely related terrestrial species and (2) the effect of mycorrhizal fungi to plant growth using in vitro symbiotic germination tests and in situ germination experiments in natural habitats. In epiphytic Liparis fujisanensis (Orchidaceae) and terrestrial L. kumokiri, their mycorrhizal fungi differ in their ITS sequences and in the responses of plant germination and growth. It suggests that a shift of mycorrhizal fungi can be one of key innovations that allowed the evolution of epiphytic L. fujisanensis. Other studies using some epiphytes were also performed.
