Bartoš Group

Our group is unrevealing the structure of the plant genomes at sequence level using NGS, molecular and cytogenetic approaches and bioinformatic tools.  We helped to expand the knowledge of genome organization and function of many species, mainly cereals. Recently, our interest is shifting to the species possessing so-called „B“ or „supernumerary“ chromosomes with the aim to uncover the evolution and biology of this mysterious  component of plant genomes.
 
Our main research interests
 
  • Sorghum and maize B chromosomes
  • B chromosome nondisjunction and elimination 
  • sequencing technologies

Our group operates Sequencing Core Facility at the Institute.
