| in situ analysis of anastomosis in representative genera of arbuscular mycorrhizal fungi. | arbuscular mycorrhizal fungi (amf) form obligate symbiotic associations with plants. as a result, the role of hyphal interactions in the establishment and maintenance of common mycorrhizal networks is poorly understood because of constraints on methods for in situ analysis. we designed a rhizohyphatron that allows the examination of intact mycelia growing from whole mycorrhizal plants. plants preinoculated with spores were cultivated in a compartment with a connecting tube from which hyphae exte ... | 2011 | 21221661 |
| a new hypothesis on the strategy for acquisition of phosphorus in arbuscular mycorrhiza: up-regulation of secreted acid phosphatase gene in the host plant. | the mycorrhiza-responsive phosphatase of tagetes patula in symbiosis with glomus etunicatum was detected by electrophoresis, was purified by column chromatography, and was characterized as acid phosphatase that was secreted into rhizosphere. the n-terminal amino acid sequence was determined by a gas-phase sequencer, and a cdna fragment of the phosphatase gene (tppap1) was amplified by degenerate primers designed based on the n-terminal amino acid sequence. the full-length cdna was obtained by th ... | 2005 | 16255243 |
| congruence of fatty acid methyl ester profiles and morphological characters of arbuscular mycorrhizal fungi in gigasporaceae. | arbuscular mycorrhizal (am) fungi (order glomales, class zygomycetes) are a diverse group of soil fungi that form mutualistic associations with the roots of most species of higher plants. despite intensive study over the past 25 years, the phylogenetic relationships among am fungi, and thus many details of evolution of the symbiosis, remain unclear. cladistic analysis was performed on fatty acid methyl ester (fame) profiles of 15 species in gigaspora and scutellospora (family gigasporaceae) by u ... | 1996 | 11607684 |
