The first scientific studies related to the discovery of themycorrhizal symbiosis were performed in 1885 by Frank.The birth of this biological phenomenon is very old, itshas been estimated to be over 400 million years old, thanks to themolecular studies carried out by DNA sequencing. The analysisof fossil data has also made it possible to date the symbiosismycorrhizal fungus. It even seems that the fungimycorrhizal fungi have contributed to terrestrial colonization by theplants. In contrast to nodulation, symbiosismycorrhizal mycorrhizal fungus is essentially non-specific: aThe fungus has the ability to colonize several species ofplants, while a host plant can interact with several plants, while afungal species. In this symbiotic association, where thehost plant is connected to a network of fungus hyphae,the plant supplies organic substances to the symbiotefungal (such as sugars formed during photosynthesis) andthe latter brings him water and mineral salts in exchange.
