Evoluce zástupců rodu řeřišnice (Cardamine, Brassicaceae) z oblasti Anatolie, Kavkazu a Balkánského poloostrova

Kantor, Adam

This thesis aims to elucidate evolution of the members of the selected species groups of the genus Cardamine, which is a species-rich genus with cosmopolitan distribution and very complex evolutionary history. The studied species were represented by hygrophytic perennials, with the focus laid on their diversity in the Balkan Peninsula and Southwestern Asia, with the emphasis put on the Anatolica-Caucasus region. These regions harbour global biodiversity hotspots and important glacial refugia, yet, they have been largely understudied in terms of knowledge of evolutionary mechanisms and environmental factors that have played there a role of plants diversification and speciation drivers. In this thesis, questions concerning the phylogeny and taxonomy of the studied groups were addressed, with aim to determine the role of polyploidy and hybridization in their evolution. Hyb-Seq was the majorly applied method, representing a technique based on next-generation sequencing, which has proven to be a very efficient and versatile method for resolving evolutionary questions. An integrative approach was employed, combining Hyb-Seq with a variety of other karyological, molecular, cytogenetic and ecological niche modelling methods, which provided a very complex insight into the addressed topics.
