Project

Relationships of ploidy level, genome and cell size in model polyploid fish with cytological and physiological impacts on conservation and culture. (GA523/08/0824)

Genome size in fishes is positively correlated to cell and nuclear size and volume. Increases in genome size due to shifts in ploidy level influence these cytological correlates causatively, with this effect persisting on both ancie...

Ploidy and hybrid diversity in sturgeons (Acipenseriformes) and its impacts on conservation and breeding (GA14-02940S)

Sturgeons, most probably of (paleo)allopolyploid origin, are of enormous ploidy diversity; species differing with ploidy levels hybridize and give hybrid progeny with intermediary ploidy level. Hybrids can...

Microevolutionary processes in marginal populations of plants with ploidy heterogeneity Hieracium echioides as a model system (KJB601110813)

The project is aimed at elucidating diversity and evolutionary dynamics of marginal populations with ploidy polymorphism in a model diploid-polyploid plant cytometry. Three umbrella questions will be addressed: i) ploidy distributio...
