Mycorrhizae under microscope labeled.
3.6.2.1 Mycorrhizae. Mycorrhizae is the mutual symbiotic association of a fungus and plant particularly in the rhizosphere of the root zone. Arbuscular mycorrhiza (AM) refers to mycorrhizas whose hyphae have extensively penetrated into the plant cells. Mycorrhiza play an important role in plant nutrient availability, particularly phosphorous.
