Host breadth is often assumed to have no evolutionary significance in broad interactions because of the lack of cophylogenetic patterns between interacting species. Nonetheless, the breadth and suite of hosts utilized by one species may have adaptive value, particularly if it underlies a common ecological niche among hosts. Here, we present a preliminary assessment of the evolution of mycorrhizal specificity in 12 closely related orchid species (genera Goodyera and Hetaeria) using DNA‐based… Expand
A narrowly endemic photosynthetic orchid is non‐specific in its mycorrhizal associations
TLDR
This work studied the spatial and temporal variability in the host fungi associated with one of the rarest North American terrestrial orchids, Piperia yadonii, to assess whether rarity of an orchid is determined by its specificity towards its fungal hosts, and indicates that orchid rarity can be unrelated to the breadth of mycorrhizal associations. Expand
Many broadly-shared mycobionts characterize mycorrhizal interactions of two coexisting epiphytic orchids in a high elevation tropical forest
TLDR
The results indicate that the studied orchids are generalists and share a broad group of mycobionts (16 OTUs) with no apparent niche segregation within or between sites. Expand
Analysis of network architecture reveals phylogenetic constraints on mycorrhizal specificity in the genus Orchis (Orchidaceae).
TLDR
It is demonstrated that evolutionary processes may be an important factor in generating patterns of mycorrhizal associations in orchids and the interaction between Orchis and Tulasnellaceae fungi is significantly influenced by the phylogenetic relationships between theOrchis species. Expand
The host bias of three epiphytic Aeridinae orchid species is reflected, but not explained, by mycorrhizal fungal associations.
TLDR
The results demonstrate that three co-occurring epiphytic orchid species did vary in their mycorrhizal specificity; however, the distribution of their my Corinthian associates did not directly explain their host associations. Expand
The biogeographical history of the interaction between mycoheterotrophic Thismia (Thismiaceae) plants and mycorrhizal Rhizophagus (Glomeraceae) fungi
TLDR
The analysis shows that Thismia plants have highly specific, phylogenetically conserved and evolutionarily persistent interactions with Rhizophagus fungi, and was able to diversify and radiate recently due to the wide geographical distribution of the host fungi. Expand
D OES MYCORRHIZAL SPECIFICITY AFFECT ORCHID DECLINE AND RARITY? 1
TLDR
The results 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
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
Highly diverse and spatially heterogeneous mycorrhizal symbiosis in a rare epiphyte is unrelated to broad biogeographic or environmental features
TLDR
It is suggested that E. firmum exhibits broad specificity and the potential for opportunistic associations with diverse fungi, which could confer symbiotic assurance when mycorrhizal fungi are stochastically available, which may be crucial in dynamic or disturbed habitats such as tropical forest canopies. Expand
The role of epiphytism in architecture and evolutionary constraint within mycorrhizal networks of tropical orchids
TLDR
This study identified a bipartite network including 73 orchid species and 95 taxonomic units of mycorrhizal fungi across the natural habitats of Reunion Island and found a highly modular architecture that largely reflected an ecological barrier between epiphytic and terrestrial subnetworks. Expand
Diversity of root-associated fungi of mature Habenaria radiata and Epipactis thunbergii colonizing manmade wetlands in Hiroshima Prefecture, Japan
TLDR
The fungal symbiont diversity of two orchid species, Habenaria radiata and Epipactis thunbergii, occupying three manmade wetlands in Hiroshima Prefecture, Japan are assessed to determine if orchids colonizing reconstructed habitats associate with a phylogenetically diverse or narrow suite of fungal Symbionts.

THE EVOLUTIONARY HISTORY OF MYCORRHIZAL SPECIFICITY AMONG LADY'S SLIPPER ORCHIDS
TLDR
Mycorrhizal specificity in genus Cypripedium appears to be an evolvable trait, and associations with particular fungi are phylogenetically conserved. Expand
Evidence for mycorrhizal races in a cheating orchid
TLDR
It is suggested that diversification and specialization of mycorrhizal associations have contributed to the rapid radiation of the Orchidaceae. Expand
Phylogenetic dispersion of host use in a tropical insect herbivore community.
TLDR
40% of caterpillar species showed significant phylogenetic clustering with respect to host plant associations, somewhat more so than for beetles or orthopteroids, which is interpreted as evidence that a substantial fraction of tropical forest insect herbivores are clade specialists. Expand

  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1998
TLDR
It is shown that host shifts have generally been more common between closely related plants than between more distantly related plants, and helps to explain the apparent large‐scale conservation in the patterns of association between insects and their host plants. Expand
Orchid-fungus fidelity: a marriage meant to last?
TLDR
The findings indicate that it is unlikely that switching fungi is a common way to improve tolerance of less severe environmental fluctuations and disturbances, and may have important implications for plant responses to severe climatic events or to more gradual environmental changes such as global warming. Expand
Differences in mycorrhizal preferences between two tropical orchids
TLDR
Both the molecular phylogeny and the seed germination experiments showed that T. variegata is a generalist in its association with fungal symbionts, and I. utricularioides is more specialized and more effective at exploiting a specific fungal clade. Expand
Evidence for novel and specialized mycorrhizal parasitism: the orchid Gastrodia confusa gains carbon from saprotrophic Mycena
TLDR
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
Two mycoheterotrophic orchids from Thailand tropical dipterocarpacean forests associate with a broad diversity of ectomycorrhizal fungi
TLDR
It is demonstrated that some green and mycoheterotrophic orchids in tropical regions can receive carbon from ectomycorrhizal fungi, and thus from trees, in contrast to most previous studies of myco heterotrophic plants, which have been mainly focused on temperateOrchids. Expand
