appropriate management of soil phosphorus (p) fertility in highly calcareous soils of iran as around the world should rely upon sound knowledge about the phosphorus reserve and its bioavailability. despite numerous reports on the positive effects of vesicular arbuscular mycorrhizae (vam) fungi on phosphorus uptake which is associated to ectomycorrhiza as a branch of two major branches of group ...

in order to investigate the response of mycorrhizal fungi to different kinds of fungicides and phytohormone balance in soybean, the present study was carried out during 2008-2009 at research site of azad university of karaj branch as factorial based on randomized complete block design with two factors and four replications. treatments were all combination of arbuscular mycorrhizal fungi species...

Mycorrhizal fungi constitute a key functional group of soil biota that greatly contribute to productivity and sustainability of terrestrial ecosystems. These are ubiquitous components of most of the ecosystems throughout the world and are considered key ecological factors in governing the cycles of major plant nutrients and in sustaining the vegetation cover (van der Hejden eta!. 1998; Requena ...

Colonization of the land by plants some 400 million years ago was associated with the colonization of their primitive roots by soil-borne filamentous fungi (Nicolson, 1975; Simon et al., 1993; Taylor et al., 1995). Today, 90% to 95% of land plants still maintain some type of mycorrhizal association so that “mycorrhizas, not roots, are the chief organs of nutrient uptake by land plants” (Smith a...

In the Northeast of Brazil, expansion of guava crops has been impaired by Meloidogyne enterolobii that causes root galls, leaf fall and plant death. Considering the fact that arbuscular mycorrhizal Fungi (AMF) improve plant growth giving protection against damages by plant pathogens, this work was carried out to select AMF efficient to increase production of guava seedlings and their tolerance ...

Gene copy number polymorphism was studied in a population of the arbuscular mycorrhizal fungus Glomus intraradices by using a quantitative PCR approach on four different genomic regions. Variation in gene copy number was found for a pseudogene and for three ribosomal genes, providing conclusive evidence for a widespread occurrence of macromutational events in the population.

Arbuscular mycorrhizal fungi (AMF) have become attractive as bio stimulants in agriculture due to plant nutrient uptake enchantment and stress tolerance [...]

• We tested the prediction that the abundance and diversity of arbuscular mycorrhizal (AM) fungi are influenced by resource availability and plant community composition by examining the joint effects of carbon dioxide (CO(2) ) enrichment, nitrogen (N) fertilization and plant diversity on AM fungi. • We quantified AM fungal spores and extramatrical hyphae in 176 plots after 7 yr of treatment wit...

Broomsedge (Andropogon virginicus L.) is a dominant grass revegetating many abandoned coal-mined lands in West Virginia, USA. Residual soils on such sites are often characterized by low pH, low nutrients, and high aluminium. Experiments were conducted to assess the resistance of broomsedge to limited phosphorus (Pi) availability and to investigate the role that arbuscular mycorrhizal (AM) fungi...
