Vesicules of endomycorrhizae in root

A section of plant feeder root that is heavily colonized by a desirable fungus called "endomycorrhizae". The structures within the root were nutrient-absorbing "arbuscules" that have converted to "vesicles" or spores. Another name for endomycorrhizae is "vesicular-arbuscular mycorrhizae ", or VAM. Where VAM is colonizing a root, that portion will be protected from root rot fungi and parasitic nematodes. VAM are symbiotic with plant roots. They take some nutrients from the sap that the plant can afford and reach out into the soil for phosphorus, other minerals and water.
