Arbuscular mycorrhizal fungi are major components of soil microbiota and mainly interact with other microorganisms in the rhizosphere. Mycorrhiza establishment impacts plant physiology some nutritional physical properties rhizospheric soil. These effects alter development root or mycorrhizas resulting from activity microorganisms. The rhizosphere plants (mycorrhizosphere), is inhabited by large...

Evidence of the fundamental role of below-aboveground links in controlling ecosystem processes is mostly based on studies done with soil herbivores or mutualists and aboveground herbivores. Much less is known about the links between belowground and aboveground mutualisms, which have been studied separately for decades. It has not been until recently that these mutualisms-mycorrhizas and legume-...

In order to clarify the functional role of individual ectomycorrhizal (EcM) fungal species in the field, we need to relate their abundance and distribution as mycorrhizas to their abundance and distribution as extramatrical mycelium (EMM). We divided each of four 20 cm x 20 cm x 2 cm slices of pine forest soil into 100 cubes of 2 cm x 2 cm. For each cube, ectomycorrhizas were identified and the...

The roots of the majority of tree species are associated with either arbuscular mycorrhizal (AM) or ectomycorrhizal (EM) fungi. The absorptive roots of tree species also vary widely in their diameter. The linkages between root thickness, mycorrhiza type and nutrient foraging are poorly understood. We conducted a large root ingrowth experiment in the field to investigate how absorptive roots of ...

Fungi profoundly affect nearly all terrestrial ecological processes and events; accurate information on the fungal component is required to adequately understand how ecosystems function (Trappe and Luoma 1992). When fungal mycelia form particular associations with a host plant’s fine roots, a symbiotic organ forms, called a mycorrhiza. Through this structure the plant provides carbohydrates to ...
