The research group

By the time this Research Group joined the Nitrogen Fixation Research Center in 1999, the laboratory of Otto Geiger had discovered the phosphatidylcholine synthase pathway, which constitutes a major route for phosphatidylcholine (lecithine) formation in bacteria. This finding started a research line aimed to understand how molecules of the bacterial membrane or cell surface modify defense responses of eukaryotic hosts thus allowing long-lasting or permanent infections which can lead to symbiotic or pathogenic interactions with the host.
