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.
Similar to mycorrhiza, endophytic colonization by fungi may benefit both partners. Endophytes of grasses give their host more resistance to grazers and get food and shelter from the plant in return. Bacteria in mycorrhiza. Mycorrhizal roots offer excellent ecological niches for other microbes. Mycorrhizal fungi may host bacteria that complete their life cycles within fungal cells. One of the best known is Geosiphon pyriforme, which can host cyanobacteria inside characteristic bladders. Arbuscular mycorrhiza (AM) fungi are unique in hosting bacteria in their cytoplasm.
