Sažetak
Crops’ wild relatives host a wide range of microorganisms, including some beneficial species that are not found or are under-represented in the domesticated crops. Our goal was to study the underexplored composition of root-associated fungal communities in endangered wild grapevines. We found high taxonomic diversity representing multiple trophic guilds that include beneficial symbiotrophs and endophytes. Soil factors explain a relatively small part of their overall variability. In contrast, the majority of the associated fungal taxa shows a close fit to the neutral model for prediction of their distributions. Only beneficial arbuscular mycorrhizal fungi and the pathogenic Ilyonectria depart from the neutral distribution model and form intimate interactions with the plant host. In addition, pathogenic fungi rarely occurred in samples that included ectomycorrhizal fungi, which suggested potentially applicable intermicroorganism interactions. High abundance and diversity of fungal endophytes on the wild grapevine roots highlight the need for their careful consideration in future studies.
