PhD student position on crossover recombination in Arabidopsis: A PhD student position is available in the Laboratory of Genome Biology led by Dr Piotr Ziolkowski at the Adam Mickiewicz University, Poznan, Poland. Meiosis is a specific type of cell division that, by reducing the number of chromosomes, produces gametes and enables sexual reproduction.

At the heart of meiosis is crossover recombination, which allows the genetic information of both parents to be shuffled. Our lab studies the factors and pathways that control meiotic crossover formation in plants. This project will use the natural accession of the model plant Arabidopsis thaliana to understand how differences in DNA sequence between parents affect crossover distribution and frequency.

By applying genome editing to these accessions, we will introduce mutations in selected genes related to crossover formation. Next, we will use genome-wide sequencing analyzes to investigate the crossover pattern in different hybrids. We will also study the activity of recombination hotspots using our recently developed technique of high-resolution crossover mapping, which is based on recombinant molecule sorting and Illumina-based sequencing.

The successful candidate will have master degree in biotechnology, biology or related field and a solid knowledge in molecular biology and genetics. Candidates with a good background and hand-on experience on Arabidopsis molecular genetics and bioinformatics skills are encouraged to apply. The project would significantly benefit from applying Arabidopsis meiotic cytology, therefore this expertise is considered an advantage.

We offer: Supportive and stimulating environment in international, friendly and well-equipped research group, Access to newly developed methodology and cutting-edge technologies in plant genetics
and molecular biology, A chance to develop new skills in research, paper writing and grant application

This position is part of a collaborative project funded by the NCN (Polish National Science Centre) together with Dr Charlie Underwood, Max Planck Institute for Plant Breeding Research, Cologne funded by DFG (German Research Foundation).
