Mission

The independent research group Meiosis (ME) primarily funded by the German Federal Ministry of Education and Research (project HERBY) and the European Research Council (project MEIOBARMIX) is interested in the process of plant meiosis that generates genetic variation through homologous recombination.

Our research is closely-linked to the research theme of the department Breeding Research and we contribute with our research to the IPK research theme FSP3 "Mechanisms of Reproduction".

Barley (Hordeum vulgare) is an important cereal crop grown in a variety of climates globally used as animal fodder, food and for brewing. Traditional plant breeding, that harnesses natural genetic variation arising during meiosis, will have a key role to deliver crop improvements in the near future.

Meiosis assures genetic variation by regulated parental genetic exchange based on homologous recombination. However, particularly in cereal crops including barley meiotic recombination events are limited and skewed towards chromosome ends whereby a large portion of the genetic information keeps untapped in breeding programs.

Projects

Embarking on molecular genetics, biochemistry and cytogenetic approaches, the overarching aim of the group is to alter the outcome of meiotic recombination with a focus on barley. To do so, projects in the group aim to:

  • better understand the mechanisms underlying the control of homologous recombination in both barley and Arabidopsis thaliana, 
  • to develop novel tools and strategies to study and alter meiotic recombination outcome,
  • and to translate acquired knowledge into barley.
