3 Abstract The importance of arbuscular mycorrhizal (AM) symbiosis for survival and growth of many plant species is generally recognized. It has been repeatedly shown that symbiosis with mycorrhizal fungi can increase the fitness of many plant species. This increasing fitness is caused by increased uptake of phosphorus and other nutrients or pathogen protection. Most studies on mycorrhizal associations explore these types of relationship using single plant population and single fungal species. This contrasts with many studies that show local adaptations of plant populations to environmental conditions. Recently it has also been shown that fungal species may have themselves different adaptations at different localities. Inspite of this knowledge only few recent studies consider both differences between plant populations and their possible local adaptations to environmental conditions at their localities as well as differences in the abundance and composition of AM fungal communities and possible local adaptations of plants directly to these communities. We studied interactions of plants from different populations of Aster amellus (an endangered species of the Czech Republic) with AMF in their natural habitats and in a pot experiment where plants from different populations were inoculated with two different...
