Srovnávací analýza genomů dvoudomých rostlin
 Bačovská, Nela
In the plant kingdom, only about one tenth of the species have different sexes. Since plant sex chromosomes are in general younger (and not always distinguishable from autosomes) than animal sex chromosomes, it is interesting to analyze them. This data can then be used in agricultural research in terms of growing exlusively one type of sex or using sex-linked genes for breeding. Because of polyploidization and long-term selection of only agriculturaly advantageous features, it seems fit to find a model plant which has not been subjected to artificial selection and could be used for the study of natural genome evolution. In this study, we chose Mercurialis annua and its close relative Mercurialis huetii for comparative analysis of their genomes and sex chromosomes which seem to be undergoing the first stage of degeneration.

Molekulární fylogeneze a genetická diverzita nejbližších příbuzných rodu Pisum
 Bačovská, Nela
Phylogenetics has given us a unique possibility to learn the history of species evolution and their interconnection on the planet. Our earlier relience only on outter morphological features for taxon classification is now being completed and even replaced by molecular-biological studies for clarification. It is possible to use our knowledge when searching for geographical origins of organisms, their expansion and change of genetic information, which are all the needed foundations for species diversification. In this work we used the family Fabaceae for the study of evolutionary genetics. Then we chose Lathyrus neurolobus for further examination of the potential use of SSR and iPBS markers for Pisum intergenus studies.
