Mycorrhizas in ecological interactions

摘要: Mycorrhizal symbioses are prevalent in all major terrestrial biomes. The researchers now actively addressing the questions that relate to biology of mycorrhizal plants natural environments, such as whether there impacts colonization on fitness individual plants. Do fungi influence outcome competitive interactions? Investigations have explored contributions mycorrhizas individuals and species, outcomes interactions between possibility status may change both ability coexist diversity plant assemblages. With wider recognition structural functional among different partnerships, has come appreciation interdependence fungal partners lead changes fungal, well communities. This chapter discusses current research understanding ecological mycorrhizas. stimulatory effects some classes bacteria processes ectomycorrhiza (ECM) roots heightened awareness complexities microbial soil. There many reports incidence severity diseases caused by pathogens. variable influenced nutrition, relative density inoculum pathogen fungus, or not were before being challenged with propagules pathogen. It long been recognized hyphae arbuscular (AM) important binding agents Exudates from quite specialized types suggested be contributors stabilization soil structure AM fungi. multitrophic mechanisms even less understood. They are, however, likely play significant roles nature.
