Plant species in the subfamily Monotropoideae are mycoheterotrophs; they obtain fixed carbon from photosynthetic plants via a shared mycorrhizal network. Previous findings show mycoheterotrophic plants exhibit a high level of specificity to their mycorrhizal fungi. In this study we explore the association of mycorrhizal fungi and Monotropa uniflora (Monotropoideae: Ericaceae) in eastern North America. We collected M. uniflora roots and nearby basidiomycete sporocarps from four sites within a…

Mycorrhizal features and fungal partners of four mycoheterotrophic Monotropoideae (Ericaceae) species from Yunnan, China

A comparison with accompanying fungus sporocarps revealed that the fruiting fungal community significantly differed from that associated with the Monotropoideae roots, so that a clear fungal preference was evident.

Russulaceae Associated with Mycoheterotroph Monotropa uniflora (Ericaceae) in Tlaxcala, Mexico: A Phylogenetic Approach

The preference of M. uniflora to associate with Russulaceae, in particularly with Russula species, is confirmed and gasteromycetation appears to have exclusively evolved in clades that also harbor species developing mycoheterotroph associations.

Mycorrhizal fungi associated with Monotropastrum humile (Ericaceae) in central Japan

The DNA sequences of the internal transcribed spacer region from fungal and plant nuclear ribosomal DNAs were analyzed to assess the genetic diversity of the fungi associated with M. humile roots and to position the plant with respect to known Monotropoideae groups, respectively.

Monotropastrum humile var. humile is associated with diverse ectomycorrhizal Russulaceae fungi in Japanese forests

Results suggest that Japanese M. humile populations are associated with specific but diverse fungi that are common ectomycorrhizal symbionts of various forest canopy trees, indicating a tripartite mycorrhIZal relationship in the forest ecosystem.

Culturable fungal endophytes in roots of Enkianthus campanulatus (Ericaceae)

The results indicated that Enkianthus houses variable root mycobionts including putative endophytic and mycorrhizal fungi in addition to AM fungi, except for AM fungi.

Reevaluating the Species Status of the Southern Ghost Pipe, Monotropa brittonii (Ericaceae)

Based on molecular and morphological analysis of Monotropa collected throughout its range in the United States, two distinct lineages are found, one of which corresponds morphologically and geographically to Small's M. brittonii and another which appears to parasitize almost exclusively Lactifluus subgenus Lactariopsis section Albati.

Comparative analysis of the reproductive ecology of Monotropa and Monotropsis: Two mycoheterotrophic genera in the Monotropoideae (Ericaceae).

This study's results revealed that taxa are largely outcross-pollinated and specialized toward Bombus pollinators, and provides insight into possible limitations in reproductive traits imposed by a mycoheterotrophic life history.

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.

Monotropoid Mycorrhizal Characteristics of Monotropa uniflora (Ericaceae) Collected from a Forest in Korea

Thick mantles covered the roots and fungal pegs inside the epidermal cells of theroots were observed, supporting the strong specificity between M. uniflora and Russula species.

Monotropa uniflora: morphological and molecular assessment of mycorrhizae retrieved from sites in the Sub-Boreal Spruce biogeoclimatic zone in central British Columbia

Increased evidence of low diversity and high specificity in the Monotropa-fungus relationship is provided and it is suggested that M. uniflora associates uniquely with fungi in the family Russulaceae in central B.C.

Fine‐level mycorrhizal specificity in the Monotropoideae (Ericaceae): specificity for fungal species groups

The results indicate that both the macro‐ and microevolution of the Monotropoideae are tightly coupled to their mycorrhizal symbionts.

Extreme specificity in epiparasitic Monotropoideae (Ericaceae): widespread phylogenetic and geographical structure

The phylogenetic patterns observed indicate that: each of the 13 plant phylogenetic lineages identified is specialized to a different genus or species group within five families of ectomycorrhizal Basidiomycetes; in sympatry, there is no overlap in mature plant fungal symbionts even if the fungi and the plants are closely related.

Epiparasitic plants specialized on arbuscular mycorrhizal fungi

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.

On the origins of extreme mycorrhizal specificity in the Monotropoideae (Ericaceae): performance trade‐offs during seed germination and seedling development

The allopatric exceptions support the idea that performance trade‐offs may be based on a coevolutionary arms race and that host range can be broadened most readily when naïve fungal hosts are encountered in novel settings.

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.

Evolution of extreme specialization within a lineage of ectomycorrhizal epiparasites

Using molecular identification methods it is shown that some monotropes are highly specific in their fungal associations and at least one species, Pterosporo andromedea is specialized on a single species group within the genus Rhizopogon.

The evolutionary ecology of myco-heterotrophy.

The focus is on what is arguably the best understood example, the monotropoid mycorrhizal symbiosis, and the overarching goal is to lay out the questions that remain to be answered about the biology of myco-heterotrophy and epiparasitism.

The molecular revolution in ectomycorrhizal ecology: peeking into the black‐box

Results from these studies have revealed that EM communities are impressively diverse and are patchily distributed at a fine scale below ground, but there is a poor correspondence between fungi that appear dominant as sporocarps vs. those that seem dominant on roots.

ITS primers with enhanced specificity for basidiomycetes ‐ application to the identification of mycorrhizae and rusts

ITS1‐F/ITS4‐B preferential amplification was shown to be particularly useful for detection and analysis of the basidiomycete component in ectomycorrhizae and in rust‐infected tissues.
