Arbuscular mycorrhizal fungi and nitrogen uptake
Archives of Microbiology, 2010Nitrogen (N) is among the most important macro-nutrients significantly affecting plant growth and yield production. Accordingly, N must be supplied adequately so that optimum amounts of yield are resulted. There are different ways of supplying N to the plant including the use of chemical and biological fertilization.

Genome diversity in arbuscular mycorrhizal fungi
Current Opinion in Plant Biology, 2015Arbuscular mycorrhizal fungi (Glomeromycota) are the most widespread and important symbionts of plants. They cannot be cultured without plants, are apparently asexual, and have multiple nuclei in a common cytoplasm. There is evidence for genetic variation among nuclei, and for segregation of this variation during growth, but these findings remain ...

The Genetics of Arbuscular Mycorrhizal Fungi
2021Sexual reproduction is an important process amongst eukaryotic organisms, with one function being to maintain genetic variation. The idea that complex eukaryotic species can persist for millions of years in the absence of sex defies fundamental evolutionary dogma, yet a group of organisms known as ancient asexuals were thought to have evolved clonally ...

The Ecology of Arbuscular Mycorrhizal Fungi
Critical Reviews in Plant Sciences, 2012Arbuscular mycorrhiza is a mutually beneficial biological association between species in the fungal phylum Glomeromycota and higher plants roots. The symbiosis is thought to have afforded green plants the opportunity to invade dry land ca 450 Ma ago and the vast majority of extant terrestrial plants retain this association.

Ancestral Lineages of Arbuscular Mycorrhizal Fungi (Glomales)
Molecular Phylogenetics and Evolution, 2000Using new and existing 18S rRNA sequence data, we show that at least five species of glomalean fungi lie outside the previously defined families and diverged very early in the evolution of that group. These five fungi would have been missed by many previous ecological studies because their sequences are not well matched to available taxon-specific ...

Plant carbon nourishment of arbuscular mycorrhizal fungi
Current Opinion in Plant Biology, 2017Reciprocal nutrient exchange between the majority of land plants and arbucular mycorrhizal (AM) fungi is the cornerstone of a stable symbiosis. To date, a dogma in the comprehension of AM fungal nourishment has been delivery of host organic carbon in the form of sugars.

Ecology of Arbuscular Mycorrhizal Fungi
2014It is a well-established fact that arbuscular mycorrhizal (AM) fungi improve plant growth. The main effect of AM fungi in improving plant growth is through improved uptake of nutrients, especially phosphorus, which is due to exploration by the external hyphae of the soil beyond the root hair and phosphorus depletion zone.

Ecology and Evolution of Multigenomic Arbuscular Mycorrhizal Fungi
The American Naturalist, 2002Arbuscular mycorrhizal fungi (AMF) form extremely important mutualistic symbioses with most plants. Their role in nutrient acquisition, plant community structure, plant diversity, and ecosystem productivity and function has been demonstrated in recent years.
