How llamas help us understand nitrogen-fixing symbiosis
PhD defence, Friday 19 May 2023, Henriette Rübsam
Legumes engage in symbiosis with nitrogen-fixing bacteria, which makes them less dependent on nitrogen fertilizers. During her PhD studies, Henriette Rübsam investigated how legume receptors that recognize symbiotic bacteria interact to activate signaling. Henriette Rübsam established a synthetic approach based on llama-derived nanobodies to drive the assembly of receptor complexes and showed which receptors form the core symbiotic complex.
The new research findings will aid in engineering symbiosis with nitrogen-fixing bacteria into other crops like barley, which might contribute to using less nitrogen fertilizers in the future.
The PhD study was completed at the Department of Molecular Biology and Genetics, Faculty of Natural Sciences, Aarhus University.
