Ancestral Lineages of Arbuscular Mycorrhizal Fungi (Glomales)

Molecular Phylogenetics and Evolution, 2000
Using new and existing 18S rRNA sequence data, we show that at least five species of glomalean fungi lie outside the previously defined families and diverged very early in the evolution of that group. These five fungi would have been missed by many previous ecological studies because their sequences are not well matched to available taxon-specific ...

Glomus, the Largest Genus of the Arbuscular Mycorrhizal Fungi (Glomales), Is Nonmonophyletic

Molecular Phylogenetics and Evolution, 2001
Arbuscular mycorrhizal (AM) fungi form a widespread and ecologically important symbiosis with plants in the land ecosystem. The phylogeny of the largest presently accepted genus, Glomus, of the monogeneric family Glomaceae (Glomales; AM fungi) was analyzed. Phylogenetic trees were computed from nearly full-length SSU rRNA gene sequences of 30 isolates,

Occurrence of some Glomales in Finland

Mycorrhiza, 1995
By using trap plants, 17 species of arbuscular mycorrhizal fungi (AMF) belonging to the order Glomales were identified in 266 soil samples collected in the period 1987–1989. Of the identified isolates, 87.1% belonged to the genus Glomus Tulasne & Tulasne, 8.5% to Acaulospora Gerdemann & Trappe, 4.1% to Scutellospora Walker & Sanders and 0.3% to ...

A Revision of the Genus Sclerocystis (Glomaceae, Glomales)

Mycologia, 1990
The genus Sclerocystis was established by Berkeley and Broome in 1873 with their description of S. coremioides and since then 13 additional species have been described. Although some consider Sclero? cystis allied to the genus Glomus, we conclude that the two genera are distinct based on spore ontogeny and sporocarp habit.

Sporocarpic Endogonales and Glomales in the scats of Rattus and Perameles

Mycological Research, 1994
Fifteen species of fungi in the Glomales and Endogonales (Zygomycetes) were recovered from faecal pellets of species of Rattus and the bandicoot Perameles nasuta in the Sydney region and from Rattus villosissimus in the Simpson Desert. Fungi were recovered in all seasons of the year.

Intraspecific ITS Polymorphism inScutellospora castanea(Glomales, Zygomycota) Is Structured within Multinucleate Spores

Fungal Genetics and Biology, 1999
Polymorphism of the internal transcribed spacers (ITS) of the ribosomal DNA in Scutellospora castanea (Glomales, Zygomycota) and its organization among spores were evaluated. Polymerase chain reaction (PCR) amplification with ITS1/ITS4 primers yielded several fragments of different lengths, even from single spores.

Problems with Fixation and Embedding of Arbuscular Mycorrhizal Fungi (Glomales)

Mycologia, 1993
In order to conduct ultrastructural studies to clarify the nature of the spores formed in Glomales, an order of arbuscular mycorrhizal fungi, techniques for fixation and embedding of these spores were tested. Of nine methods, none was effective for fixation of Acaulospora, Gigaspora, and Scutellospora spores, but one was efficient for fixation of ...

Names and epithets in the Glomales and Endogonales

Mycological Research, 1993
In a recent paper, Almeida (1989) wrote about the names and epithets used in the Endogonales sensu lato , commenting on their derivations, and providing a list of names he considered should be used in preference. Almost all of these changes were erroneous, and, with four exceptions, the original names should be retained.

Taxonomy and phylogeny of the Glomales

1994
The importance of arbuscular mycorrhizal fungi in nutrient uptake by plants has been intensively studied (e.g., Sanders et al., 1974; Gianinazzi-Pearson and Gianinazzi, 1986). The fungal partners in these symbioses are currently placed in the Zygomycetes in the order Glomales.
