ABSTRACT: Arbuscular mycorrhizal fungi (AMF) can increase the acquisition of silicon (Si) and, therefore, alleviate problems caused by metallic toxicity in plants, but this effect remains poorly understood. The objective was to evaluate influence Si application on growth Leucaena leucocephala inoculated with AMF (Claroideoglomus etunicatum) a soil contaminated manganese (Mn). We exposed plants ...

UNLABELLED Arbuscular mycorrhizal (AM) fungi form mutualisms with plant roots that increase plant growth and shape plant communities. Each AM fungal cell contains a large amount of genetic diversity, but it is unclear if this diversity varies across evolutionary lineages. We found that sequence variation in the nuclear large-subunit (LSU) rRNA gene from 29 isolates representing 21 AM fungal spe...

July 2006 | Volume 4 | Issue 7 | e239 The interaction between plant roots and Glomeromycota fungi [1]—arbuscular mycorrhiza (AM)—is probably the most important symbiotic association in nature. More than 80% of all higher land plant species are able to benefi t from the fungus’ ability to extract nutrients, mostly phosphorus, from the soil. In exchange, it has been estimated that worldwide up to...

Symbiosis, defined as prolonged and close association of two or more different organisms, is a major driving force for expansion of biological diversity from genes to ecosystems. In the most intimate form, the symbiont lives inside the cells of its host, is heritable, and the two parties could no longer survive independently. Such heritable endosymbiosis blurs the line of what constitutes an in...

in a greenhouse experiment, the effects of glomus intraradices and indigenous mycorrhizal isolates from soils under plow and no-till treatments on the uptake of 32p placed at 1, 2.5 and 4 cm from the roots of white clover (trifolium repens) in 23, 37 or 46 days after planting were compared.spores of the indigenous fungi were mostly a mixture of glomus mossea, g. clarum, g. caledonium and g....
