A mycorrhiza[1] is a symbiotic (generally mutualistic, but occasionally weakly pathogenic) association between a fungus and the roots of a higher plant. In a mycorrhizal association, the fungus colonizes the host plant's roots, either intracellularly or extracellularly. They are an important component of soil life.[2]
Definitions of mycorrhiza
- "Mycorrhizas are symbiotic associations essential for one or both partners, between a fungus (specialised for life in soils and plants) and a root (or other substrate-contacting organ) of a living plant, that is primarily responsible for nutrient transfer. Mycorrhizas occur in a specialised plant organ where intimate contact results from synchronised plant-fungus development."[3]
- "A mycorrhiza is a symbiotic (generally mutualistic, but occasionally weakly pathogenic) association between a fungus and the roots of a vascular plant. In a mycorrhizal association, the fungus colonizes the host plant's roots, either intracellularly as in arbuscular mycorrhizal fungi (AMF), or extracellularly as in ectomycorrhizal fungi. They are an important component of soil life and soil chemistry.[4]
- "The symbiotic association of the mycelium of a fungus with the roots of a seed plant"[5]
How many plants form mycorrhiza
- "While it is clear that the majority of plants form mycorrhizas, the exact percentage is uncertain, but it is likely to lie somewhere between 80% and 90%. In many of these associations between 10% and 30% of the food produced by the plant moves through to the fungi."[6]
Chunks of information
- Do you know how long all the root segments of the entire root system of a single rye plant can become? According to Brian Capon in his book 'Botany for gardeners' it was once measured. The figure is unbelievable: 380 miles or 630 km.[7]
Ericoid mycorrhiza
Ericoid mycorrhiza[8] are a symbiotic relationship between fungi and the roots of plants from the order Ericales (for example tea, blueberry, azalea).
