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
