Leguminous plants engage into beneficial relationship with rhizobia – soil bacterial able to enter plant roots and fix atmospheric nitrogen. This process, called nodulation, is regulated by plant hormones auxin and cytokinin. During his studies, Marcin developed specific tools enabling for visualization of auxin and cytokinin. His studies on hormonal dynamics in root demonstrated that auxin accumulates during rhizobial entry to the roots. He showed that this accumulation is caused by local auxin synthesis and that inhibition of auxin synthesis reduces infection. Moreover, his research revealed a link between auxin and cytokinin in nodulation. Marcin’s research provided fascinating insights into hormonal regulation of nodulation and led to a better understanding of the symbiosis.

The PhD degree was completed at the Department of Molecular Biology and Genetics, Science and Technology, Aarhus University.
