Evidence for novel and specialized mycorrhizal parasitism: the orchid Gastrodia confusa gains carbon from saprotrophic Mycena
The results demonstrate for the first time using molecular and mass-spectrometric approaches that myco-heterotrophic plants gain carbon through parasitism of wood or litter decaying fungi. Expand
Mycorrhizal diversity in Apostasia (Orchidaceae) indicates the origin and evolution of orchid mycorrhiza.
We demonstrated that "orchid mycorrhiza," a specialized mycorrhizal type, appeared in the common ancestor of the largest plant family Orchidaceae and that the fungal partner shifted fromExpand
The Physiological Ecology of Mycoheterotrophy
This chapter provides a comparative overview of the current knowledge on carbon and nitrogen isotope natural abundance in partially and fully mycoheterotrophic plants associated with ectomycorrhizal, wood- and litter-decomposer saprotrophic, and arbuscular mycorrhIZal fungi, and discusses their ecophysiological implications.

Shifts in mycorrhizal fungi during the evolution of autotrophy to mycoheterotrophy in Cymbidium (Orchidaceae).
It is demonstrated that shifts in mycorrhizal fungi correlate with the evolution of nutritional modes in plants and gradual shifts in fungal partners through a phase of coexistence of different types of mycobionts may play a crucial role in the evolutionof mycoheterotrophic plants. Expand
Evolution of host breadth in broad interactions: mycorrhizal specificity in East Asian and North American rattlesnake plantains (Goodyera spp.) and their fungal hosts
A preliminary assessment of the evolution of mycorrhizal specificity in 12 closely related orchid species using DNA‐based methods suggests a role for phylogenetic conservatism in maintaining suits of fungal hosts among plants. Expand
Epipactis helleborine shows strong mycorrhizal preference towards ectomycorrhizal fungi with contrasting geographic distributions in Japan
It is indicated that mycorrhizal association with geographically restricted pezizalean ectomycorrhIZal fungi is a key control upon this orchid species’ distribution across widely different forest habitats. Expand
High mycorrhizal specificity in a widespread mycoheterotrophic plant, Eulophia zollingeri (Orchidaceae).
The data provide evidence that a mycoheterotrophic plant can achieve a wide distribution, even though it has a high mycorrhizal specificity, if its fungal partner is widely distributed, and the molecular data support the wide distribution and wide-ranging habitat of thisfungal partner. Expand
Arbuscular mycorrhiza formation in cordate gametophytes of two ferns, Angiopteris lygodiifolia and Osmunda japonica
Mycorrhizal formation in wild fern gametophytes, based on large-scale sampling with molecular identification of host plant species, was demonstrated for the first time and results suggest that A.lygodiifolia and O.japonica gamETophytes consistently form arbuscular mycorrhIZae. Expand
The giant mycoheterotrophic orchid Erythrorchis altissima is associated mainly with a divergent set of wood-decaying fungi.
The results show that E. altissima is associated with a wide range of wood- and soil-inhabiting fungi, the majority of which are wood-decaying taxa, which enables this giant orchid to access a large carbon pool in woody debris and has been key to the evolution of such a large mycoheterotroph.

Arbuscular mycorrhizal colonization in field-collected terrestrial cordate gametophytes of pre-polypod leptosporangiate ferns (Osmundaceae, Gleicheniaceae, Plagiogyriaceae, Cyatheaceae)
This study provides the first evidence for AM fungal colonization of wild gametophytes in the Plagiogyriaceae and Cyatheaceae, suggesting that mycorrhizal associations with AM fungi could widely occur in terrestrial pteridophytes. Expand
