THE EVOLUTION OF MYCORISIAN FUNG AS SYMBIOTIC PARTNERS

Abstract

The article analyzes the evolution of mycorrhizal fungi, which served as symbiotic partners in association with plants, more precisely with their root system. The advantage brought by the existence of mycorrhizal symbioses for plant nutrition, highlighted the influence this association has on plant growth and development. The existence of mycorrhizal fungi was demonstrated approximately 400 million years ago, the first discoveries being the fossils of Aglaophyton major plants that showed traces of arbuscules, these being considered edifying transfer structures for the vesicular-arbuscular endomycorrhizal type. Mycorrhizae are present in mature ecosystems, ecosystems that present a cyclical and unitary evolution of the components between the biotic and abiotic unit, at which point the mycorrhizal associations have the role of regulating the assimilation of food resources for the plants with which they are associated. In this association, hyphae play an important role in the nutrient cycle, having the function of stopping losses from the ecosystem
