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.
Fungi in mycorrhizae form a mutualistic relationship with the roots of most plant species. The roots in the relationship, and the plants themselves are referred to as mycorrhizal if mycorrhizae are formed.While only a small proportion of all species has been examined, 95% of those plant families are predominantly mycorrhizal. They are named after their presence in the plant's rhizosphere (root system).his type of mycorrhiza occurs in the subfamily Monotropoideae of the Ericaceae. These plants are heterotrophic or mixotrophic and derive their carbon from the fungus partner. This is thus a non-mutualistic, parasitic type of mycorrhizal symbiosis.
