Wide Hybridization Group

Our group is studying various aspects of interspecific and intergeneric hybridization and polyploidization. We use molecular cytogenetics, flow cytometry, bioinformatics, genomics and molecular biology techiques to analyze genome composition, evolution and function of hybrid genomes. Our objects are Festuca x Lolium hybrids (Festulolium) and hybrids of wheat x rye and wheat x barley.

Our current topics cover:

  •           meiosis and genome stability of wide hybrids
  •           3D organization of hybrid nucleus
  •           parental-specific gene expression

Nuclear organization in interspecific plant hybrids
Leader
David Kopecký Ph.D.
The plant cell nucleus is enclosed within the nuclear envelope harboring chromosome territories (CTs) and various nuclear bodies. It seems that the spatial organization of chromosomes is nonrandom and is characterized by many local and long-range contacts among genes and regulatory elements. Thus, it is evident that the architecture of interphase chromosomes plays a role in the regulation of gene expression. The introduction of sophisticated high . . .
