A mycorrhiza (Greek: Î¼ÏÎºÏÏ, mykÃ³s, fungus, and ÏÎ¯Î¶Î±, riza, root, pl. mycorrhizae or mycorrhizas) is a symbiotic association between a fungus and the roots of a vascular host plant. The term mycorrhiza refers to the role of the fungi in the plants' rhizosphere, its root system. Mycorrhizae play important roles in soil biology and soil chemistry.
Examples. 1  Rhizobia- Rhizobia are bacteria that conduct Nitrogen fixation for legume plants. 2  Mycorrhizae- Mycorrhizae are similar to rhizobia in that they interact with plants at their roots. 3  Arbuscula: found in non-woody and tropical plants.  Ectomycorrhiza: found in boreal and temperate 1  forests. Ericoid: found in species of the heathland.
