Mycorrhizae establish symbiotic relationships with plants and play an essential role in plant growth, disease protection, and
overall soil quality. There are two main categories of Mycorrhizae relationships: Endomycorrhizal fungi (Arbuscular Mycorrhizal
Fungi) (AMF) form relationships with over 90% of plants (including turf grasses). Ectomycorrhizae fungi form relationships with
only about 2% of plants, but some of them are quite common. In this scientific review, we will only talk about Endomycorrhizal.
Mycorrhizae described in current scientific literature, the Endomycorrhizal the most abundant and widespread. The molecular
basis of nutrient exchange between Arbuscular Mycorrhizal (AM) fungi and host plants is presented. The role of AM fungi in disease
protection, Root colonisation by Arbuscular Mycorrhizal Fungi (AMF) can improve plant resistance/tolerance to biotic stresses.
Although this bio protection has been amply described in different plant systems, the underlying mechanisms remain largely
unknown. Besides mechanisms such as improved plant nutrition and competition, experimental evidence supports the involvement
of plant defense mechanisms in the observed protection. During mycorrhiza establishment, modulation of plant defenses responses
occurs upon recognition of the AMF in order to achieve a functional symbiosis. As a consequence of this modulation, a mild, but
effective activation of the plant immune responses may occur, not only locally but also systemically. This activation leads to a primed
state of the plant that allows a more efficient activation of defense mechanisms in response to attack by potential enemies.
