AMONG the Eukaryota, the true fungi comprise four divisions (Chytridiomycota, Zymogomycota, Ascomycota and Basidio-mycota) that constitute a natural group which is thought to have diverged about 1 billion (109) years ago, believed also to be the time of divergence between metaphyta and metazoa lineages1. The endosymbionts responsible for the most prevalent plant root symbiosis, the vesicular–arbuscular mycorrhizae (VAM) or, more appropriately, arbuscular mycorrhizae, comprise 130 species of… 
The Old Arbuscular Mycorrhizal Symbiosis in the Light of the Molecular Era
TLDR
The permanence of this mutualistic association during evolution reflects its importance in nature and the benefits of the symbiosis to the maintenance of natural ecosystems cannot be only estimated in terms of improved plant nutrition.
Plants, Mycorrhizal Fungi and Endobacteria: a Dialog Among Cells and Genomes
TLDR
Experimental data support the current view that mycorrhizal symbioses are often tripartite associations, and demonstrate that during colonization the cellular organization of the two eukaryotes is completely remodeled.
The ecology and evolution of the arbuscular mycorrhizal fungi
TLDR
It is suggested that understanding the evolution and genetic structure of this enigmatic group of fungi may be the key to understanding how they function in ecosystems.
Phylogeny of the glomeromycota (arbuscular mycorrhizal fungi): recent developments and new gene markers.
TLDR
Nuclear-encoded rDNA and rpb1 protein gene sequences are used to reassess the phylogeny of the Glomeromycota and discuss possible implications.
Coevolution of roots and mycorrhizas of land plants.
TLDR
It is hypothesised that roots gradually evolved from rhizomes to provide more suitable habitats for mycorrhizal fungi and provide plants with complex branching and leaves with water and nutrients.
Morphological and Molecular Identification of Arbuscular Mycorrhizal (AM) Fungi
The impulse that the majority of land plants are dependent on symbiotic microorganisms for growth and survival is now well established, the importance of soil microbes as regulators of plant
Arbuscular mycorrhizal associations in Lycopodiaceae.
TLDR
The results suggest that most mycoheterotrophic plants that form AM associations do so with restricted clades of Glomus A, and raises the possibility that photosynthetic sporophytes are a source of carbon to conspecific myco heterotrophic gametophytes via shared fungal networks.
7 Evolution of the ‘Plant-Symbiotic’ Fungal Phylum, Glomeromycota
TLDR
The focus here is, after reporting some historical aspects, on the recently advanced understanding of molecular phylogenetic relationships, the evolution and biogeography, and the obligate symbiotic endobacteria of AM fungi.
Update on Symbiosis Carbon Metabolism and Transport in Arbuscular Mycorrhizas
Colonization of the land by plants some 400 million years ago was associated with the colonization of their primitive roots by soil-borne filamentous fungi (Nicolson, 1975; Simon et al., 1993; Taylor

EVOLUTIONARY RELATIONSHIPS AMONG ARBUSCULAR MYCORRHIZAL FUNGI IN THE ENDOGONACEAE
A cladistic analysis of 57 species in six genera ofthe Endogonaceae was performed using 27 mor? phological characters of asexual spores and the endophytic phase of mycorrhizal development. These
Vesicular-arbuscular mycorrhizae from the Triassic of Antarctica
TLDR
The fungi associated with the Antarctic roots provide the most complete and convincing evidence for prePleistocene VA mycorrhizae in the fossil record and are compared with possible Paleozoic analogs from the Devonian and the Pennsylvanian.
Advances in the Study of Vesicular-Arbuscular Mycorrhiza
TLDR
With improved techniques, very striking effects of inoculation on plant growth and phosphate uptake have been demonstrated beyond doubt, and this has led to studies of the uptake mechanism and the source of the extra phosphate.
Specific amplification of 18S fungal ribosomal genes from vesicular-arbuscular endomycorrhizal fungi colonizing roots
TLDR
A polymerase chain reaction primer (VANS1) is developed that enables the specific amplification of a portion of the vesicular-arbuscular endomycorrhizal fungus small subunit rRNA directly from a mixture of plant and fungal tissues.
Date of the monocot-dicot divergence estimated from chloroplast DNA sequence data.
TLDR
The results imply that the angiosperm lineage emerged in Jurassic-Triassic time, which considerably predates its appearance in the fossil record (approximately 120 Myr ago), which can be taken as an upper bound for the age of angiosperms.
Relative-Rate Test for Nucleotide Substitutions between Two Lineages
TLDR
The relative-rate test of Wu and Li ( 1985) is extended to cases where more than one taxon are sampled for one nucleotide sequence in two lineages compared, and formulas for calculating both the weighted number of substitutions in each lineage as compared with a common reference taxon and the variance of the difference in the weightedNumber of nucleotide substitutions between the two lineage are presented.
The early evolution of eukaryotes: a geological perspective.
TLDR
Polecular phylogenies of eukaryotic organisms imply patterns of biological and environmental history that can be tested against the geological record, and Precambrian rocks show evidence of episodic increases in biological diversity and atmospheric oxygen concentrations.
