Lay Summary (Englisch)

Lay summary
Arbuscular mycorrhizal fungi (AMF) are an ancient group that form their own phylum within the fungal kindom. AMF form important symbioses with plants, helping them to take up essen-tial nutrients and promoting plant diversity. In this project, we are studying the genetics of this fungal group. In the current period of the project we have shown that AMF harbour genetically different nuclei and that these different nuclei are passed from parent to offspring during spore formation, even though the spores are produced clonally. Underground the fungi form an ex-tensive network connecting plants of different species. The network was only thought to grow clonally. However, in this project, we have shown that hyphae of genetically different AMF fuse and genetic material is exchanged. This completely changes our understanding of the genetics of this important group of plant symbionts. Firstly, these fungi can no longer be considered as having lived for the last 400 million years in the absence of genetic exchange. Secondly, becau-se we were able to create viable genetic crosses between genetically and phenotypically different AMF, our study lays the foundation for experimentally studying the genetics, control of compa-tibility/incompatibility and the genetic architecture of phenotypic traits in this important fungal phylum.
