The presence of VAM enhances uptake of nutrients in general but particularly of P.
The hyphae of VAM penetrate the roots of host plants, and form specialized structures within arbuscles and sometimes vesicles.
Mycorrhizae help increase the surface area of the plant root system because hyphae, which are narrow, can spread beyond the nutrient depletion zone.
Hyphae are long extensions of the fungus, which can grow into small soil pores that allow access to phosphorus otherwise unavailable to the plant.
