I have always been fascinated by plants \u2013 by the remarkable diversity of their shapes, flower colours, growth forms and life strategies. My research focuses on how this diversity we find in plants has been shaped by fundamental evolutionary processes leading to plant adaptation and speciation. In the centre of my focus is polyploidisation (whole genome duplication), a major-effect mutation acting as a primary trigger of sympatric speciation in plants. I aim to elucidate the key evolutionary mechanisms operating at various stages of polyploid speciation, which are important for the potential evolutionary success of polyploid lineages (e.g., origin and local establishment of polyploid mutants, adaptive potential of new traits in polyploids, inter-ploidy introgression).<\/p><\/div>\n<\/div>\n\n\n\n

I am generally interested in phenotypic effects of DNA-content variation (including but not limited to polyploidy) and their putative adaptive potential. I primarily work with microscopic unicellular algae (chrysophytes in particular), model systems highly suitable for experimental evolution studies. Flow cytometric analysis of microalgae often requires modification of the applied nuclei isolation \/ staining procedures, which also belongs among my interests.<\/p><\/div>\n<\/div>\n\n\n\n

I am interested in factors affecting the strength of reproductive isolation in diploid – autotetraploid systems, and in geographic and genome-wide patterns of across-ploidy introgression.
This involves field sampling throughout the contact zone of cytotypes in Tripleurospermum inodorum<\/em> and manipulated across-ploidy crosses over several consecutive generations.<\/p><\/div>\n<\/div>\n\n\n\n

I am interested in patterns and rates of across-ploidy gene flow between the diploid and triploid cytotype of Butomus umbellatus<\/em>. This includes studying the potential for across-ploidy breeding in mixed-ploidy populations and assessing the putative role of unreduced (2n<\/em>) gametes.<\/p><\/div>\n<\/div>\n\n\n\n

I am interested in temporal dynamics of diploid – polyploid coexistence within the mixed-ploidy populations of plants. Particularily in how a negative frequency-dependent selection acting against minority cytotypes could be alleviated by specific biological properties of plant species and\/or environmental heterogeneity.<\/p><\/div>\n<\/div>\n\n\n\n

I am interested in reproductive interactions of cytotypes within mixed-ploidy populations. Particularly in the success of across-ploidy matings, in the origin of triploid hybrids and their evolutionary potential in mediating gene flow between diploids and tetraploids of Tripleurospermum inodorum<\/em>.<\/p><\/div>\n<\/div>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n
