Record 1 2007-03-05

English

Subject field(s)
  • Fungi and Myxomycetes
  • Plant Biology
DEF

Species of mycorrhizal fungus with hyphae that penetrate and live inside the cortical cells of the plant root.

CONT

Endomycorrhizal fungus ... grows in the roots of grass and many other plants. It forms a partnership with shrubs and grass. The fungus gives the plants minerals like phosphorus. The plant gives the fungus sugars and other carbohydrates.

OBS

There are two types of mycorrhizal fungi: ectomycorrhizae and endomycorrhizae. Ectomycorrhizae form sheaths around plant roots, endomycorrhizae enter cortex cells in the roots.

OBS

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.

CONT

Par un ensemble de techniques mises au point chez la légumineuse-modèle [...] on a déterminé le mécanisme cellulaire précis par lequel le champignon endomycorhizien traverse la barrière externe de la racine.

OBS

[Le terme «endomycorhize» est] composé du préfixe endo- du grec, endon (dedans) 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'endomycorhize est la] symbiose entre la racine d'une plante et une colonie de champignons, les hyphes de ces derniers (leurs filaments) s'infiltrant à l'intérieur des cellules racinaires, dans l'espace intracellulaire.
