Fossilized fungal hyphae and spores from the Ordovician of Wisconsin (with an age of about 460 million years) strongly resemble modern arbuscular mycorrhizal fungi (Glomales, Zygomycetes). These fossils indicate that Glomales-like fungi were present at a time when the land flora most likely only consisted of plants on the bryophytic level. Thus, these fungi may have played a crucial role in facilitating the colonization of land by plants, and the fossils support molecular estimates of fungal… Expand
Molecular identification and phylogeny of arbuscular mycorrhizal fungi
TLDR
Ribosomal DNA sequences indicate that the diversity within the Glomales on the family and genus level is much higher than previously expected from morphology-based taxonomy. Expand
Molecular identification and phylogeny of arbuscular mycorrhizal fungi
The fossil record and molecular data show that the evolutionary history of arbuscular mycorrhizal fungi (Glomales) goes back at least to the Ordovician (460 million years ago), coinciding with theExpand
The liverwort Marchantia foliacea forms a specialized symbiosis with arbuscular mycorrhizal fungi in the genus Glomus.
TLDR
This work suggests that certain liverwort species may serve as a model for studying DNA sequence variation in colonizing AM phylotypes and specificity in AM-host relationships. Expand
Communities, populations and individuals of arbuscular mycorrhizal fungi.
TLDR
This review critically examines the concepts of species, communities, populations and individuals of arbuscular mycorrhizal fungi. Expand
Occurrence of fungal structures in bryophytes of the boreo-nemoral zone
TLDR
Fungal structures were observed in bryophyte stem and leaf tissues, and in rhizoids, and the AM association with brysophytes was observed to be symbiotic. Expand
2 Molecular Approaches to Arbuscular Mycorrhiza Functioning
TLDR
Fungi of the order Glomales (Zygomycota) form with the roots of most land plants a mutualistic symbiosis named arbuscular mycorrhiza which gives access for the plant to low mobile elements like phosphorus (Smith and Gianinazzi-Pearson 1988). Expand
Germination shields in Scutellospora (Glomeromycota: Diversisporales, Gigasporaceae) from the 400 million-year-old Rhynie chert
Glomeromycotan spores from the Lower Devonian Rhynie chert provide the first evidence for germination shields in fossil fungi and demonstrate that this complex mode of germination was in place inExpand
Glomus, the largest genus of the arbuscular mycorrhizal fungi (Glomales), is nonmonophyletic.
TLDR
A new family, separate from the Glomaceae, is required to accommodate this group of organisms, initially named Diversisporaceae fam. Expand
Co-occurrence of three fungal root symbionts in Gaultheria poeppiggi DC in Central Argentina
TLDR
The evolutionarily derived position of Gaultheria within the Ericales may suggest that G. poeppiggi recently acquired the ability to form arbuscular mycorrhizas rather than having retained it from ancestral lines. Expand
Lichen-Like Symbiosis 600 Million Years Ago
TLDR
The discovery of lichen-like fossils preserved in marine phosphorite of the Doushantuo Formation at Weng'an, South China indicate that fungi developed symbiotic partnerships with photoautotrophs before the evolution of vascular plants. Expand

Silurian fungal remains: probable records of the Class Ascomycetes
TLDR
It is suggested that these microfossils obtained from the late Silurian Burgsvik Sandstone represent the remains of the imperfect stages of terrestrial Ascomycetes, and provide evidence for an origin of this group at least contemporaneous with the earliest land plants. Expand
The oldest fossil ascomycetes
TLDR
The oldest ascomycetous fungi with flask-shaped ascocarps in thin-section preparations of the Lower Devonian Rhynie chert of Aberdeenshire, Scotland are found, underscoring the diversity of fungal-plant interactions early in the colonization of the land. Expand

Origin and diversification of endomycorrhizal fungi and coincidence with vascular land plants
TLDR
The phylogenetic analyses confirm the existence of three families within arbuscular fungi on the basis of morphological characters and obtain approximate dates for the divergence of major branche's on the phylogenetic tree, consistent with the hypothesis that VAM were instrumental in the colonization of land by ancient plants.

Mixed arbuscular mycorrhizae from the Triassic of Antarctica

This work has provided the first fossil representative of the Gigasporineae and supports current rDNA esti- mates of the age of the lineage, and is the first reported instance of a mixed colony of arbuscular endomycorrhizae in the fossil record. Expand
The origin of land plants: a matter of mycotrophism.
TLDR
It is hypothesized that terrestrial plants are the product of an ancient and continuing symbiosis of a semi-aquatic ancestral green alga and an aquatic fungus-an oomycete that were equipped to cope with the problems of desiccation and starvation associated with terrestrial existence. Expand
