Scutellospora savannicola: redescription, epitypification, DNA barcoding and transfer to Dentiscutata

Mycological Progress, 2014
An arbuscular mycorrhizal fungus (AMF) was isolated from a south Ecuadorian reforestation site in the vicinity of a pristine mountain rainforest ecosystem. Morphologically, it corresponded with the description of an AMF first described from Cuba as Gigaspora savannicola, before it was placed in Scutellospora.

Ultrastructure of spore development in Scutellospora heterogama

Mycorrhiza, 2007
The ultrastructural detail of spore development in Scutellospora heterogama is described. Although the main ontogenetic events are similar to those described from light microscopy, the complexity of wall layering is greater when examined at an ultrastructural level. The basic concept of a rigid spore wall enclosing two inner, flexible walls still holds

Morphological, ontogenetic and molecular characterization of Scutellospora reticulata (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.

DNA cloning and screening of a partial genomic library from an arbuscular mycorrhizal fungus, Scutellospora castanea

Mycorrhiza, 1994
A technique has been developed to efficiently extract purified, restrictable genomic DNA from spores of different arbuscular mycorrhizal fungi in order to begin detailed investigations of the genome of the Glomales. The protocol yielded variable amounts of DNA depending on the fungal species; for Scutellospora castanea and Gigaspora rosea it reached ...

Scutellospora rubra, a new arbuscular mycorrhizal species from Brazil

Mycological Research, 1999
Scutellospora rubra is a new arbuscular mycorrhizal species trapped in a pot culture of rhizosphere soil from Eucalyptus dunnii. Spores are dark red-brown, 140–220 μm diam., and closely resemble those of S. heterogama in size, colour, and subcellular organization, but the outer layer of the spore wall is smooth rather than ornamented.

Scutellospora Arenicola and Glomus Trimurales : Two New Species in the Endogonaceae

Mycologia, 1989
San Miguel Island is the westernmost member ofthe Channel Islands and is situated 42 km off the coast of southern California. This small is? land (37 km2) is transversed by three major sand dune fields (Johnson, 1980) that account for ca 15% ofthe habitable island surface. Examination of soil samples collected from around the roots of plants growing in

Ontogeny and phylogeny of a Scutellospora heterogama mutant, with implications for morphological recognition of species in Glomeromycota

Fungal Biology, 2010
A putative mutant of Scutellospora heterogama has been maintained for 19 pot culture generations over 15y. The mutant differed phenotypically from the wild-type parental lineage in characteristics of the spore wall: albino versus pigmented red-brown color, high plasticity in acidic mutants versus rigid and finely laminate, deep red-purple reaction ...

Ontogenetic comparisons of arbuscular mycorrhizal fungi Scutellospora heterogama and Scutellospora pellucida: revision of taxonomic character concepts, species descriptions, and phylogenetic hypotheses

Canadian Journal of Botany, 1994
The taxonomic significance of morphological characters in fungi of Glomales (Zygomycetes) has been based solely on superficial resemblance. Ontogenetic comparisons among isolates of Scutellospora pellucida and Scutellospora heterogama were used to resolve discrete stages of differentiation in which characters were delimited and ordered hierarchically ...

Foraging strategies of the external mycelium of the arbuscular mycorrhizal fungi Glomus intraradices and Scutellospora calospora

Applied Soil Ecology, 2008
The responsiveness of the external mycelium of Glomus intraradices and Scutellospora calospora was tested in a multiple-choice experimental system in which mycelium encountered patches amended with nitrogen (N) or phosphorus (P), either alone or in combination with a host plant.

Detection of the arbuscular mycorrhizal fungus Scutellospora heterogama within roots using polyclonal antisera

Mycological Research, 1995
The antigenic properties of the arbuscular mycorrhizal Scutellospora heterogama (BEG 35) were studied to develop a serological method for detecting the fungus in roots. Three polyclonal antisera were raised against the combined soluble and particulate fraction of spores of S. heterogama (BEG 35) and used in serological tests.
