Species of mycorrhizal fungus with hyphae that grow only between the cells and over the surface (outside) of the roots, but do not penetrate the plant cell. 5, record 1, English, - ectomycorrhizal%20fungus

There are two types of mycorrhizal fungi: ectomycorrhizae and endomycorrhizae. Ectomycorrhizae form sheaths around plant roots, endomycorrhizae enter cortex cells in the roots. 6, record 1, English, - ectomycorrhizal%20fungus

A mycorrhiza (typically seen in the plural forms mycorrhizae or mycorrhizas, Greek for fungus roots) is the result of a mutualistic association between a fungus and a plant. This mutualism takes place at the root level, where individual hyphae extending from the mycelium of a fungus colonize the roots of a host plant, either intracellularly or extracellularly. 7, record 1, English, - ectomycorrhizal%20fungus

Morphologiquement, l'ectomycorhize est plus facile à reconnaître que l'endomycorhize parce que les hyphes (cellules) du champignon ectomycorhizien associé, l'enrobent et forment autour d'elle un tissu fongique coloré (manchon fongique) comparable à une douille qui recouvre et protège la pointe d'un stylo. 3, record 1, French, - champignon%20ectomycorhizien

Les champignons ectomycorhiziens jouent un rôle très important dans l'absorption, le transfert ou l'immobilisation d'autres éléments minéraux du sol : cuivre, fer, zinc et potassium, ainsi que des métaux lourds présents en excès dans les sols acides (aluminium, cadmium, zinc) qui sont accumulés dans les cordons mycéliens. Les champignons sont de bons détoxificateurs des sols. 4, record 1, French, - champignon%20ectomycorhizien

Composé du préfixe ectondo- du grec ectos (dehors) et du nom mycorhize (symbiose entre la racine d'une plante et un champignon), qui vient lui aussi du grec par son préfixe myco- de mycetos (champignon) et son suffixe -rhize de -rrhizos dérivé de rhiza (racine, fondement). [L'ectomycorhize est le phénomène de] symbiose entre la racine d'une plante et une colonie de champignons, les hyphes de ces derniers (leurs filaments) s'infiltrant entre les cellules racinaires, dans l'espace intercellulaire. 5, record 1, French, - champignon%20ectomycorhizien
