Project Type: B - national grants (GA ČR, GA AVČR)
Realization from: 2008
Realization to: 2010
Summary: The project is aimed at elucidating diversity and evolutionary dynamics of marginal populations with ploidy polymorphism in a model diploid-polyploid plant Hieracium echioides. A number of interacting techniques of contemporary plant biology will be used, including molecular approaches (AFLP, cpDNA sequencing and PCR-RFLP) and flow cytometry. Three umbrella questions will be addressed: i) ploidy distribution at various spatial scale across Central Europe; ii) genetic diversity at population level with respect to cytotype composition, population size, and degree of isolation; and iii) origin of polyploids in the area investigated. The gathered data will provide novel and multifaceted insights into micro-evolutionary processes that shape variation in populations at the edge of distribution and will contribute to better understanding of the role of marginal populations in genesis, maintenance, and dynamics of diversity (of practical value in conservation biology).
