Selected projects

Project no: 2013 – 2017 APVV-0139-12

Agency: Agency for the support of research and development of the Slovak Republic

Period of the project realization: 1.10. 2013 - 30. 9. 2017

Title of the project: Species and genetic diversity in the Brassicaceae family - towards understanding of evolution in polyploid complexes.

Brief characterization of the project: The project addresses polyploid evolution by conducting a comparative study of polyploid complexes from three different tribes of Brassicaceae. Polyploidy is an evolutionary significant phenomenon widespread in the angiosperms, but still poorly understood especially when considering non-model specise. The main aim of the project is to get insights into the patterns and processes of polyploid evolution in natural populations. The project is focused on diversity centres of the studied polyploid complexes, representing hotspots of genetic and species variation and highly dynamic systems form a micro-evolutionary perspective. The project is aimed at reconstructing main evolutionary forces and speciation processes acting in this crucifers and polyploid complexes in general.

Title of the project: Evolutionary processes and reproduction strategies in the genus Onosma

Period of the project realization: 01/2015 - 12/2018.

Brief characterization of the project: Hybridization and polyploidization are considerable processes in plant evolution. The species of the genus Onosma, O. arenaria and O. pseudoarenaria, are allopolyploids, their bimodal karyotypes consist of large L and small S chromosomes. While tetraploid O. pseudoarenaria (LLSS genome) is probably sexual, in triploid O. arenaria (LLS) hemisexuality was observed. In this reproduction mode an uncertain mechanism assures biparental inheritance of L and matroclinal inheritance of S chromosomes. The aim of the project is to test the hypotheses about reproduction modes of hybrids of the genus Onosma through the study of mother plants, their pollen and seeds using molecular (AFLP, nrDNA, cpDNA), cytometric (FCM, FCSS) and cytogenetic (GISH, FISH) methods. The results will contribute to basic research of hemisexuality in O. arenaria and will clarify interactions of L and S subgenomes. This should lead to future use of O. arenaria as a model group in study of mechanisms and evolution of permanent odd polyploidy.

Title of the project: Developmental biology, polyploidization a intercytotype interaction in sexual-asexual plant systems.

Period of the project realization: 01/2019 - 12/2022.

Brief characterization of the project: Three plant groups characterised by the coexistence of diploid sexual and polyploid asexual (apomictic/hemisexual) cytotypes selected from genera Crataegus, Sorbus and Onosma will be studied in the project. The aim of the project is to elucidate the development of pollen grains, their cytotype frequency in pollen of polyploids, interactions between diploids and polyploids in relation to pollination and fertilization in mixed-cytotype populations, and structural and cytoembryological aspects of embryo and endosperm formation in developing and mature seeds. Standard methods of plant reproductive biology, experimental plant crosses, microscopic techniques, cytotype screening of mother plants and their seeds using classical karyology and flow cytometry, will be used. The results should contribute to the detailed characterization of reproduction modes in asexual plants and to better understanding of the population precesses and the evolution of plant groups with coexistence of sexuals and their related asexuals.
