UNLABELLED The root system of most terrestrial plants form symbiotic interfaces with arbuscular mycorrhizal fungi (AMF), which are important for nutrient cycling and ecosystem sustainability. The elucidation of the undergoing changes in plants' metabolism during symbiosis is essential for understanding nutrient acquisition and for alleviation of soil stresses caused by environmental cues. Withi...

Arbuscular mycorrhizal fungi (AMF) are multinucleated and coenocytic organisms, in which the extent of the intraisolate nuclear genetic variation has been a source of debate. Conversely, their mitochondrial genomes (mtDNAs) have appeared to be homogeneous within isolates in all next generation sequencing (NGS)-based studies. Although several lines of evidence have challenged mtDNA homogeneity i...

In a study on coprophilous fungi, different samples including cow, sheep and horse dung and mouse feces were collected from different locations in West and East Azarbaijan provinces (NW Iran). Isolation of the fungi was done based on moist chamber culture method. Purification of the isolated fungi was done by single spore culture method. Several fungal taxa were obtained. Identification of the ...

Coffee seedlings are commonly produced on substrate composed of a mixture soil and cattle manure, supplemented with chemical fertilizers. Alternatives to reduce production costs produce greater quality health include the use commercial organic substrates, which require less handling. The beneficial microorganisms such as arbuscular mycorrhizal fungi (AMF) can be considered good alternative for ...

the morphological diversity of arbuscular mycorrhizal fungi (amf) at the anguran zn and pb mining region (zanjan province, iran) were studied along a transect from the mine to 4500 m away. within each plot, a composite sample of root and rhizospheric soil from a dominant indigenous plant was collected. the soil samples were analyzed for their physico-chemical characteristics. spores were extrac...

Arbuscular mycorrhizal fungi (AMF) are widely distributed in nature. They live in the roots of higher plants, in a symbiotic relationship. In this study, five commercial species of yams (Dioscorea spp.) were inoculated with six species of AMF, Glomus clarum, G. etunicatum, G. fasciculatum, Gigaspora sp., G. mosseae, and Acaulospora sp., in field cultivation conditions to investigate the influen...

Yerba mate (Ilex paraguariensis St. Hill.) is an important woody tree in South America, however the production of quality seedlings a major problem. Microorganisms that promote plant growth have shown to be efficient biotechnologies seedlings. The arbuscular mycorrhizal fungi (AMF), it establishes symbiosis with several species and increases accumulation biomass absorption poorly mobile nutrien...
