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.
April 10, 2019: Our paper "Inter-morphotype hybridization in tall fescue (Festuca arundinacea Schreb.): Exploration of meiotic irregularities and potential for breeding" has been accepted in Euphytica.
February 25, 2019: Our paper "Out-of-position telomeres in meiotic leptotene appear responsible for chiasmate pairing in an inversion heterozygote in wheat (Triticum aestivum L.)" has been published in Chromosoma.
December 12, 2018: Our paper "Misdivision of telocentrics and isochromosomes in wheat" has been accepted in Cytogenetic and Genome Research.
September 2018: Marco Mendes, visiting PhD student from Brazil, joined our team. Welcome!

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 . . .
