"The edaphic adaptation of AM fungi to adverse conditions of serpentine soils and the contribution of AM symbiosis to plant tolerance of serpentine syndrome were evidenced. However, superior importance of AM symbiosis in serpentine soils was not found."@en . "The proposed project is designed to test the hypothesis whether arbuscular mycorrhizal (AM) symbiosis belongs among adaptation mechanisms important for the survival of plants on serpentine soils. Knautia arvensis was selected as a model plant because it inhabits serpentine as well as non-serpentine soils, both as diploids and tetraploids. This experimental system will allow testing the effects of AM fungi and genome duplication (incl. their interactions) on plant growth under adverse conditions of serpentine soils. A set of methodical approaches will be combined, including field data collection, experimental cultivation, and laboratory methods. Plant populations of different origin (serpentine vs. non-serpentine, diploid vs. tetraploid) will be compared in terms of the effects of native AM fungi on plant growth and heavy metal uptake in serpentine soil. The gathered data will provide novel insights into the role of biotic factors in plant performance under stressful soil conditions."@en .
