Analysis of bacterial communities associated with spores of Gigaspora margarita and Gigaspora rosea
Plant and Soil, 2008The spores of arbuscular mycorrhizal fungi (AMF) form a unique microhabitat that is suitable for the colonization by many species of bacteria. The aim of the current study was to analyze the bacterial communities associated with the surface of spores of the AMF species Gigaspora margarita MAFF 520054 and Gigaspora rosea JP1.

Microbe Profile: Gigaspora margarita, a multifaceted arbuscular mycorrhizal fungus
Microbiology, 2022Gigaspora margarita is a cosmopolitan arbuscular mycorrhizal fungus, which - as an obligate symbiont- requires being associated to a host plant to accomplish its life cycle. It is characterized by huge white spores, the development of extraradical auxiliary cells, and the lack of intraradical vesicles.

Observations on extra-matrical vesicles of Gigaspora margarita in vitro
Transactions of the British Mycological Society, 1985Observations on the formation and development of vesicles by Gigaspora margarita suggest that they could be a potential source of inoculum for this VA fungus.

Intrasporal variability of ribosomal sequences in the endomycorrhizal fungus Gigaspora margarita
Molecular Ecology, 1999The sequence variability of the ribosomal internal transcribed spacer (ITS) region, which comprises the 5.8 gene and the flanking regions ITS1 and ITS2, was investigated in the arbuscular mycorrhizal fungus Gigaspora margarita. DNA analysis of a multispore preparation and three single spores led to the identification of 11 slightly different sequences (

Intraradical hyphae phosphatase of the arbuscular mycorrhizal fungus, Gigaspora margarita
Biology and Fertility of Soils, 1998An alkaline phosphatase in the intraradical hyphae of arbuscular mycorrhizal fungi was found to be closely related to an improvement of plant growth. To detect the phosphatase activity in a crude extract of mycorrhizal roots, phosphatase isozymes in mycorrhizal and non-mycorrhizal onion roots were compared with those in Gigaspora margarita by ...

Expression of chitin synthase genes in the arbuscular mycorrhizal fungus Gigaspora margarita
New Phytologist, 1999Genomic DNA from spores of the endomycorrhizal fungus Gigaspora margarita was amplified with two sets of degenerate primers designed on conserved regions of chitin synthase polypeptides. Three chitin synthase (chs) gene portions were identified: Gimchs1, Gimchs2 and Gimchs3, encoding one class II and two class IV chitin synthases, respectively. Gimchs1

Sporulation of Gigaspora margarita on root cultures of tomato
Canadian Journal of Microbiology, 1984Use of germinated spores of Gigaspora margarita as inoculum on tomato root culture plates routinely resulted in successful mycorrhizal infections in more than 85% of inoculated root cultures. Penetration into the root, vesicle formation, arbuscule production, and new spore formation were reproducibly observed.

Spore germination of Gigaspora margarita stimulated by volatiles of soil-isolated actinomycetes
Soil Biology and Biochemistry, 1995Abstract Nineteen field isolates of actinomycetes and Streptomyces orientalis were evaluated for their production of volatile compounds that stimulate spore germination of Gigaspora margarita , an arbuscular mycorrhizal fungus. Some actinomycetes enhanced spore germination, whereas others did not.

Acidic vesicles in living hyphae of an arbuscular mycorrhizal fungus, Gigaspora margarita
Plant and Soil, 2004Localization and movement of organelles in living hyphae of an arbuscular mycorrhizal fungus, Gigaspora margarita, were observed using a combination of fluorescent probes and laser-scanning confocal microscopy. Dense, evenly distributed acidic vesicles were visible in germ tubes and extraradical hyphae using DIC with the fluorescent acidotropic probe ...
