Polyphosphates in intraradical and extraradical hyphae of an arbuscular mycorrhizal fungus, Gigaspora margarita.
The amount of polyphosphate in the intraradical and extraradical hyphae of Gigaspora margarita was estimated from successive extractions with trichloroacetic acid (TCA), EDTA, and phenol-chloroform (PC). In the intraradical hyphae, most of the polyphosphate was present in TCA- and EDTA-soluble (short-chain and long-chain) fractions, whereas most of the polyphosphate in the extraradical hyphae w...
متن کاملPopulation and function analysis of cultivable bacteria associated with spores of arbuscular mycorrhizal fungus Gigaspora margarita
This study was aimed to investigate the diversity and function of bacterial population associated with Gigaspora margarita spores. The fungus was propagated in sterilized sand/soil pots using alfalfa (Medicago sativa), grain sorghum (Sorghum bicolor), or maize (Zea mays) as host plants, or in sterilized vermiculite pots using alfalfa as host plants, respectively. Bacteria were isolated from the...
متن کاملEndobacteria affect the metabolic profile of their host Gigaspora margarita, an arbuscular mycorrhizal fungus.
The aim of this paper was to understand whether the endobacterium identified as Candidatus Glomeribacter gigasporarum has an effect on the biology of its host, the arbuscular mycorrhizal fungus Gigaspora margarita, through the study of the modifications induced on the fungal proteome and lipid profile. The availability of G. margarita cured spores (i.e. spores that do not contain bacteria), rep...
متن کاملIsolation, free-living capacities, and genome structure of "Candidatus Glomeribacter gigasporarum," the endocellular bacterium of the mycorrhizal fungus Gigaspora margarita.
"Candidatus Glomeribacter gigasporarum" is an endocellular beta-proteobacterium present in the arbuscular mycorrhizal (AM) fungus Gigaspora margarita. We established a protocol to isolate "Ca. Glomeribacter gigasporarum" from its host which allowed us to carry out morphological, physiological, and genomic investigations on purified bacteria. They are rod shaped, with a cell wall typical of gram...
متن کاملThe mitochondrial genome of the arbuscular mycorrhizal fungus Gigaspora margarita reveals two unsuspected trans-splicing events of group I introns.
• Arbuscular mycorrhizal fungi (AMF) are ubiquitous organisms that benefit ecosystems through the establishment of an association with the roots of most plants: the mycorrhizal symbiosis. Despite their ecological importance, however, these fungi have been poorly studied at the genome level. • In this study, total DNA from the AMF Gigaspora margarita was subjected to a combination of 454 and Ill...
