Abstracts |
The genus Tuber is an important ectomycorrhizal genus in Europe, forming symbiosis with a wide range of woody plants. In our research we aimed to apply phylogeography approach to analyse the geographical differentiation of Tuber species based on rDNA analysis. Available nucleotide sequences originating from S and SE Europe showed genetic differentiation and distribution in several Tuber species. The observed phylogenetic clades corresponded to the last glacial refugia pools and post-glacial migration paths of symbiotic plants (oaks). Based on the high number of the analysed Tuber ribotypes found in Slovenia, this area appears to be the encountering zone of two postglacial migration routes and an important biodiversity hot-spot. The knowledge on genetic diversity and geographic distribution of genotypes can contribute to the biodiversity and functional correlations of plant and fungal partners in ectomycorrhiza and subsequently to the forest management planning and potential cultivation of fungi.
