We're organising the PLANT MEIOSIS MEETING next year!!!

Come to Poznan, Poland, to meet with our community!

WHO WE ARE...

The variation observed between parents and their offspring is due to meiotic recombination called crossover. The crossover takes place during gamete formation and is based on exchange of chromosomal segments between parental chromosomes. In consequence, novel combinations of alleles are generated. We are interested in how crossovers are formed and how they are regulated.

Different factors that control meiotic recombination: acting in cis and trans Modified from Ziolkowski and Henderson, New Phytologist 2017.

Our primary research model is Arabidopsis thaliana - favoured species of plant scientists. However, we work also on maize and barley.
