Project

Evolution within hybridogenous population of Tragopogon does Czech population differ from those ones in US? (GA206/02/0582)

In NW part of USA, two new Tragopogon species originated after hybridisation of T. pratensis, T. dubius and T. porrifolius, all introduced from Europe. Thy were discovered about 1950 and represent the best documented origin of new species by...

Relevance of duplicated promoter sequences for the function of plant 35S rDNA intergenic spacers. (GA20-28029S)

Duplications of promoters for RNA Pol I, referred to as spacer promoters (SPs), are found within the 35S rDNA intergenic spacers (IGSs) across animals and plants. Despite wide spread occurrence, their function in plant rDNA transcription remain enigm...

The impacts of interspecific hybridization and allotetraploidization on evolution of plant genomes (GA204/05/0687)

Both genetic and epigenetic alterations in parental genomes accompanying interspecific hybridization, subsequent polyploidization and the origin of new species will be studied to answer following questions: (i) Are alterations in parental genomes ran...

Genome wide range mapping of rDNA structure and epigenetic modfications in plant hybrids using third generation single molecule real-time sequencing (GA14-34632S)

The rRNA genes are organised in long tandem arrays comprising thousands of nearly identical units. Only a minority of genes is transcribed while the rest is epigenetically inactivated. The locus is uneasy to tackle by classical molecular approaches a...
