From 400 to 450 million years ago, arbuscular mycorrhizal (AM) connections emerged and were crucial in plant colonization. A mycorrhizal relationship with ubiquitous soil fungi is formed by 80% of all known terrestrial plant species. There is a bidirectional exchange of resources across the mycorrhizal interface that benefits both partners. In addition to supplying phosphorus (P) and nitrogen (N), mycorrhizal fungi also help plants withstand biotic (root infections) and abiotic (drought, salt, heavy metals) stresses. In exchange for the mycorrhizal fungus-assisted nutrient uptake, the host plant gives back its photosynthetically fixed carbon. In addition to structural differences, AM and ectomycorrhizal (ECM) were different in associating plant species. Mycorrhizae are useful for crops that are cultivated in soils with a limited supply of nutrients. It is possible that mycorrhizal connections will result in higher nutrient concentrations in plant tissue, particularly for minerals (such as P and N) that are dependent on diffusion toward the roots for uptake. In order to manage crop nutrient levels, mycorrhizal management is becoming a more viable option, albeit there are still a number of practical issues to overcome in this application. Along with providing nutritional benefits to plants, mycorrhizal relationships with plants have the potential to compete with fungal diseases for the infection of plant roots.
