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.


  • 2021/08/06: The reference sequence of maize B chromosome was published in PNAS (Link). Our work helped to reveal a cis factor involved in mechanism underlying its non-Mendelian inheritance. Good job everyone!
  • 2021/04/03: Our group played a major role in revealing the reference sequence of the maize B chromosome. It has been released at MaizeGDB (Link).
  • 2021/10/02: Radim and Lucie attended Training school in Proteomics and Protein-Protein Interaction (INDEPTH). Thank you for having us!
  • 2021/05/02: Radim and Jan significantly contributed to the identification of gene TaMSH7-3D, responsible for Ph2 phenotype in wheat. The results were published in Nature Communications (Full text).
  • 2021/04/02: Barbora Zpěváková started to work on her bachelor thesis in our group. She is going to study B chromosome gene polymorphisms in maize landraces. Good luck!
  • 2021/22/01: Radim successfully finished his PhD studies concerning Physical mapping of Ph2 region in hexaploid wheat! Congratulations!
  • 2021/18/01: Natálie Harnádková is going to work on her bachelor thesis as part of our group. She is going to develop PCR markers specific to B chromosomes of Sorghum purpureosericeum. Her work will simplify screening for B-positive individuals!
  • 2021/15/01: A bachelor student Zdena Kašparová is a new member of our team. She is going to study Irregular transmission of the B chromosome in Sorghum purpureosericeum. We are looking forward to see the results.


Ph.D. position

Nondisjunction of the B chromosome in maize

We are looking for a new colleague to join our team as a PhD student. The student will be involved in an ongoing project focusing on the mechanism of the B chromosome nondisjunction in maize. The main focus of the work will be the detailed analysis of candidate genes controlling the nondisjunction process and the identification of their interaction partners. Candidates should have a background in molecular biology. Experience in bioinformatic analysis is an advantage.

For further details see the official announcement. The deadline for applications is 31 July 2024.
