Project

Genomic dominance as a force shaping evolution of plant wide hybrids (GA20-10019S)

Genetic and epigenetic features of rDNA intergenic spacers and their potential regulatory functions in the establishment of nucleolar dominance (GA17-11642S)

Though the epigenetic mechanisms of rDNA silencing are well known, it remains unclear how only one rDNA homeolog is chosen for inactivation in genetic hybrids, a phenomenon known as nucleolar dominance (ND). To evaluate the controve...

Biogenesis of small nucleolar RNAs in the frame of nuclear architecture (GA304/00/P025)

Cell nucleus contains many small nucleolar RNAs (snoRNA) which are necessary for production of mature ribisomes. The snorRNA are mainly involved in processing of pre-ribosomal RNA and in modification of ribosomal RNA (rRNA). All snorRNA are ...
