First cloning and characterization of two functional aquaporin genes from an arbuscular mycorrhizal fungus Glomus intraradices.
Arbuscular mycorrhizal (AM) symbiosis is known to stimulate plant drought tolerance. However, the molecular basis for the direct involvement of AM fungi (AMF) in plant water relations has not been established. Two full-length aquaporin genes, namely GintAQPF1 and GintAQPF2, were cloned by rapid amplification of cDNA 5'- and 3'-ends from an AMF, Glomus intraradices. Aquaporin localization, activ...
متن کاملNonself vegetative fusion and genetic exchange in the arbuscular mycorrhizal fungus Glomus intraradices.
Arbuscular mycorrhizal fungi (AMF) form symbioses with the majority of plants and form extensive underground hyphal networks simultaneously connecting the roots of different plant species. No empirical evidence exists for either anastomosis between genetically different AMF or genetic exchange.Five isolates of one population of Glomus intraradices were used to study anastomosis between hyphae o...
متن کاملCarbon metabolism in spores of the arbuscular mycorrhizal fungus Glomus intraradices as revealed by nuclear magnetic resonance spectroscopy.
Arbuscular mycorrhizal (AM) fungi are obligate symbionts that colonize the roots of over 80% of plants in all terrestrial environments. Understanding why AM fungi do not complete their life cycle under free-living conditions has significant implications for the management of one of the world's most important symbioses. We used (13)C-labeled substrates and nuclear magnetic resonance spectroscopy...
متن کاملGintAMT2, a new member of the ammonium transporter family in the arbuscular mycorrhizal fungus Glomus intraradices.
In the symbiotic association of plants and arbuscular mycorrhizal (AM) fungi, the fungus delivers mineral nutrients, such as phosphate and nitrogen, to the plant while receiving carbon. Previously, we identified an NH(4)(+) transporter in the AM fungus Glomus intraradices (GintAMT1) involved in NH(4)(+) uptake from the soil when preset at low concentrations. Here, we report the isolation and ch...
متن کاملPhosphate uptake, transport and transfer by the arbuscular mycorrhizal fungus Glomus intraradices is stimulated by increased carbohydrate availability.
* The influence of carbohydrate availability to mycorrhizal roots on uptake, metabolism and translocation of phosphate (P) by the fungus was examined in axenic cultures of transformed carrot (Daucus carota) roots in symbiosis with Glomus intraradices. * 14C-labelled carbohydrates, 33P-phosphate and energy dispersive X-ray microanalysis were used to follow the uptake and transfer of C and P in t...
