Because mycoheterotrophic plants fully depend on their mycorrhizal partner for their carbon supply, the major limiting factor for the geographic distribution of these plants may be the presence of their mycorrhizal partner. Although this factor may seem to be a disadvantage for increasing geographic distribution, widespread mycoheterotrophic species nonetheless exist. The mechanism causing the wide distribution of some mycoheterotrophic species is, however, seldom discussed. We identified the… Expand

Shifts in mycorrhizal fungi during the evolution of autotrophy to mycoheterotrophy in Cymbidium (Orchidaceae).
TLDR
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

Specialized mycorrhizal association between a partially mycoheterotrophic orchid Oreorchis indica and a Tomentella taxon
TLDR
The results strongly suggest that in the Oreorchis-Corallorhiza clade, full mycoheterotrophy evolved after the establishment of partial my co-heterotrophicphy, rather than through direct shifts from autotROphy. Expand
Mycorrhizal communities of two closely related species, Pyrola subaphylla and P. japonica, with contrasting degrees of mycoheterotrophy in a sympatric habitat.
TLDR
High-throughput DNA sequencing revealed that numerous common ectomycorrhizal OTUs interact with the two Pyrola species and Q. crispula, thereby providing an opportunity to exploit a certain amount of carbon from common mycorrhIZal networks. Expand
Evolutionary histories and mycorrhizal associations of mycoheterotrophic plants dependent on saprotrophic fungi.
Mycoheterotrophic plants (MHPs) are leafless, achlorophyllous, and completely dependent on mycorrhizal fungi for their carbon supply. Mycorrhizal symbiosis is a mutualistic association with fungiExpand
Age-dependent mycorrhizal specificity in an invasive orchid, Oeceoclades maculata.
TLDR
Oeceoclades maculata appears to be highly specific for fungi during seed germination, but unusually promiscuous as adult plants, which is surprising in two respects. Expand
Does mycorrhizal specificity affect orchid decline and rarity?
TLDR
The results of this study suggest that orchid rarity and persistence are not necessarily related to fungal diversity and that other factors may be more important in determining orchid persistence. Expand
Epipactis helleborine shows strong mycorrhizal preference towards ectomycorrhizal fungi with contrasting geographic distributions in Japan
TLDR
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
Identity and specificity of the fungi forming mycorrhizas with the rare mycoheterotrophic orchid Rhizanthella gardneri.
TLDR
Findings have implications for better understanding R. gardneri distribution, evolution and the ecological significance of its mycorrhizal fungus, particularly in relation to nutrient acquisition. Expand
Variation in Mycorrhizal Associations with Tulasnelloid Fungi among Populations of Five Dactylorhiza Species
TLDR
The found that the investigated species of the genus Dactylorhiza associated with a wide range of fungal OTUs from the Tulasnellaceae, some of which were widespread and common. Expand

Mycorrhizal Specificity and Function in Myco-heterotrophic Plants
TLDR
It is argued that specificity represents a continuum and can only be properly assessed using phylogenetic data, and whether myco-heterotrophic orchids interact with fungi in fundamentally different ways than do autotrophs. Expand
Fine‐level mycorrhizal specificity in the Monotropoideae (Ericaceae): specificity for fungal species groups
TLDR
The results indicate that both the macro‐ and microevolution of the Monotropoideae are tightly coupled to their mycorrhizal symbionts. Expand
Sebacinales: a hitherto overlooked cosm of heterobasidiomycetes with a broad mycorrhizal potential.
TLDR
A well-resolved phylogeny of the main lineages of basidiomycetes is presented which suggests that the Sebacinaceae is the most basal group with known mycorrhizal members, and it is evident that there is a cosm of mycor Rhizal biodiversity yet to be discovered in this group. Expand
Epiparasitic plants specialized on arbuscular mycorrhizal fungi
TLDR
It is shown that non-photosynthetic plants associate with AMF and can display the characteristic specificity of epiparasites, which suggests that AMF mediate significant inter-plant carbon transfer in nature. Expand

TLDR
Most myco-heterotrophs are entirely subterranean for most of their lives and these stages exhibit adaptations consistent with a change in function from organs of absorption to organs of storage, shown by the almost universal loss of root hairs, decrease in surface area. Expand

TLDR
It is argued that these orchids are cheaters because they do not provide fixed carbon to associated fungi, which suggests that mycorrhizae, like other ancient mutualisms, are susceptible to cheating. Expand
Communities and populations of sebacinoid basidiomycetes associated with the achlorophyllous orchid Neottia nidus‐avis (L.) L.C.M. Rich. and neighbouring tree ectomycorrhizae
TLDR
Analysis of 61 root systems from 23 French populations showed that N. nidus‐avis associates highly specifically with a group of species of Sebacinaceae, likely to derive its resources from surrounding trees, a mycorrhizal cheating strategy similar to other myco‐heterotrophic plants studied to date.

Arbuscular mycorrhizal fungi of the Glomus-group A lineage (Glomerales; Glomeromycota) detected in myco-heterotrophic plants from tropical Africa
TLDR
It is shown that the roots of two myco-heterotrophic plant individuals, besides being colonized by representatives of Glomus-group A, also contain DNA of Acaulospora sp, which is interpreted as a facultative mycorrhizal associate. Expand
Specialized cheating of the ectomycorrhizal symbiosis by an epiparasitic liverwort
TLDR
It is shown that a non–vascular plant, the non–photosynthetic liverwort Cryptothallus mirabilis, is epiparasitic and is specialized on Tulasnella species that form ectomycorrhizae with surrounding trees at four locations in England, France and Portugal. Expand
Formation of endomycorrhizas by an achlorophyllous orchid,Erythrorchis ochobiensis, andAuricularia polytricha
TLDR
The results indicated that some heterobasidiomycetous fungi could form endomycorrhizas with a myco-heterotrophic orchid and showed that the symbiont of E. ochobiensis extends, at least experimentally, to HeterobAsidiomyCetes. Expand
