mycorrhiza

A Dictionary of Biology | 2004 | Copyright

mycorrhiza The mutually beneficial association (see mutualism) formed between fungi and the roots of plants. This is a very common form of mutualism; the absorption of mineral ions by the plant roots is enhanced by the presence of the fungus, which benefits by obtaining soluble organic nutrients from the root cells. Ectotrophic mycorrhizas form a network of hyphae around the root and grow into the air spaces between the cells of the root. The hyphae of endotrophic mycorrhizas enter the cortical cells of the host roots.

mycorrhiza

A Dictionary of Plant Sciences | 1998 | | Copyright

mycorrhiza A close physical association between a fungus and the roots of a plant, from which both fungus and plant appear to benefit; a mycorrhizal root takes up nutrients more efficiently than does an uninfected root. A very wide range of plants can form mycorrhizas of one form or another, and some plants (e.g. some orchids and some species of Pinus) appear incapable of normal development in the absence of their mycorrhizal fungi. See also ECTOTROPHIC MYCORRHIZA and ENDOTROPHIC MYCORRHIZA.
