Email Facebook LinkedIn When grown under nitrogen-starved conditions, legumes engage in symbiotic nitrogen fixation with rhizobial soil bacteria. Upon recognition of their symbiont, legumes grow symbiotic organs, root nodules. The bacteria colonize these organs, where they fix atmospheric nitrogen and make it available to the host plant. Hereby the plant's need for additional fertilizer is reduced. To avoid infection by harmful microbes instead of the symbiont, legumes discriminate carefully between friend or foe.

During her PhD studies, Kira Gysel studied the initial recognition of rhizobial bacteria by plant receptor proteins. By using biochemical methods and X-ray crystallography, she improved the understanding of this highly specific process, especially how different legumes discern their specific symbiont. Furthermore, she was able to show direct recognition of the bacterial exopolysaccharide by a plant receptor.

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