New recombinations in Glomeromycota
Mycotaxon, 2011Combined morphological and molecular biological analyses have achieved major advances in the taxonomy of fungal species in phylum Glomeromycota. In this study, we analyzed which species might not yet be attributed to their correct genus, focusing on Acaulospora myriocarpa, A. undulata, A. nicolsonii, and Scutellospora nodosa.

Multinucleate Spores Contribute to Evolutionary Longevity of Asexual Glomeromycota
The American Naturalist, 2010Arbuscular mycorrhizal fungi (Glomeromycota) are the dominant symbionts of land plants and one of the oldest multicellular lineages that exist without evidence of sexual reproduction. The mechanisms that protect these organisms from extinction due to accumulation of deleterious mutations in the absence of sexual recombination are unclear. Glomeromycota

Mycological Research, 2005
The arbuscular mycorrhizal (AM) fungus Scutellospora reticulata (CNPAB11) was characterized using morphological, ontogenetic and molecular approaches. Spore ontogenesis was studied using Ri T-DNA transformed carrot roots and observations were compared with those published for eight other, pot-cultured, Scutellospora species.

Phylogenetic analysis of Glomeromycota by partial LSU rDNA sequences
Mycorrhiza, 2006We analyzed the large subunit ribosomal RNA (rRNA) gene [LSU ribosomal DNA (rDNA)] as a phylogenetic marker for arbuscular mycorrhizal (AM) fungal taxonomy. Partial LSU rDNA sequences were obtained from ten AM fungal isolates, comprising seven species, with two new primers designed for Glomeromycota LSU rDNA.

Where the wild things are: looking for uncultured Glomeromycota
New Phytologist, 2014Summary Our knowledge of Glomeromycotan fungi rests largely on studies of cultured isolates. However, these isolates probably comprise one life‐history strategy – ruderal. Consequently, our knowledge of arbuscular mycorrhizal (AM) fungi may be biased towards fungi that occur primarily in disturbed habitats and associate with disturbance‐tolerant host

Three new arbuscular mycorrhizal Diversispora species in Glomeromycota
Mycological Progress, 2015Morphological observations of spores and mycorrhizal structures of three arbuscular mycorrhizal fungi (Glomeromycota) prompted, and subsequent phylogenetic analyses of SSU–ITS–LSU nrDNA sequences confirmed, that they are undescribed species of the genus Diversispora. Morphologically, the first species, here named D. varaderana, is most distinguished by

Macroecology of Microbes – Biogeography of the Glomeromycota
2008Arbuscular mycorrhizal (AM) fungi are among the most abundant soil microorganisms, associating with 95% of plant families and occurring on all continents of the globe (Smith and Read 1997; Trappe 1987; Read 1991). All AM fungi are members of the newly created phylum Glomeromycota (Schuβler 2001).

Repetitive DNA sequences include retrotransposons in genomes of the Glomeromycota
Genetica, 2006Twenty-five repetitive elements are first described in the genomes of the arbuscular mycorrhizal (AM) fungi Gigaspora margarita, Gig. rosea and Glomus mosseae. Nineteen repetitive DNA sequences isolated by genomic library screening and four by self-priming PCR had no homology to known DNA sequences, except for two Gig.

Patterns of diversity and adaptation in Glomeromycota from three prairie grasslands
Molecular Ecology, 2013AbstractArbuscular mycorrhizal (AM) fungi are widespread root symbionts that often improve the fitness of their plant hosts. We tested whether local adaptation in mycorrhizal symbioses would shape the community structure of these root symbionts in a way that maximizes their symbiotic functioning.
