A mycorrhiza (typically seen in the plural forms mycorrhizae or mycorrhizas, Greek for fungus roots) is the result of a symbiotic association between a fungus and a plant. This symbiosis takes place at the root level, where individual hyphae extending from the mycelium of a fungus colonize the roots of a host plant. Furthermore, mycorrhizal plants are generally more resistant to diseases, such as those caused by microbial soil-borne pathogens, and are also more resistant to the effects of drought.
