Introductory video animation providing some basic information about mycorrhizas. A mycorrhiza (from Ancient Greek μύκης (múkēs) ' fungus ' and ῥίζα (rhíza) ' root '; pl. mycorrhizae, mycorrhiza, or mycorrhizas) [1] is a symbiotic association between a fungus and a plant. [2]
The mycorrhizal symbiosis between plants and fungi is fundamental to terrestrial ecosystems, with evolutionary origins before the colonization of land by plants. [17] In the mycorrhizal symbiosis, a plant and a fungus become physically linked to one another and establish an exchange of resources between one another.
Further more the fungi which mycoheterotrophically interact with orchid plants are often also found in mycorrhizal association with beech trees, [51] and translocation of photosynthate from tree to fungus and then to orchid has been proposed, but a thorough study is still lacking. [52]
Ascomycota fungi form ericoid mycorrhizas with plants of the order Ericales, and ectomycorrhizas with trees. Basidiomycota fungi form ecto-, orchid, monotropoid, arbutoid, and some ericoid mycorrhizae. Fungal hyphae are thinner than plant roots, which allows them to penetrate areas in the soil with moisture and nutrient that are inaccessible to ...
Based on the magnitude of mycorrhizal fungal inputs to the soil carbon pool, some have suggested that variation in the recalcitrance of mycorrhizal biomass may be important for predicting soil carbon storage, as it would affect the rate at which the contribution of mycorrhizal fungi to soil carbon is returned to the atmosphere. [9]
Ectomycorrhizal symbiosis, showing root tips with fungal mycelium from the genus Amanita. An ectomycorrhiza (from Greek ἐκτός ektos, "outside", μύκης mykes, "fungus", and ῥίζα rhiza, "root"; pl. ectomycorrhizas or ectomycorrhizae, abbreviated EcM) is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species.
Hydnellum peckii is a mycorrhizal species, and forms mutually beneficial relationships with a variety of coniferous trees, growing on the ground singly, scattered, or in fused masses. The fruit bodies typically have a funnel-shaped cap with a white edge, although the shape can be highly variable.
A simple way to introduce a mycoforestry system and enhance out-plantings for crops and forest restoration sites is to "use mycorrhizal spore inoculum when replanting forest lands." [2] For this process it is best to match native trees with native mycorrhizal fungi. This method keeps and will promote the functioning of the native ecosystem, and ...
