Research Focus

Our research focuses on plant amino acid metabolism in the context of environmental interactions and development. Using a combination of biochemical and omics approaches we aim to identify presently unknown reaction steps as well as biochemical mechanisms of amino acid sensing and signaling. Within CEPLAS we contribute our expertise in plant proteomics and biochemistry to unravel the functions of seed storage proteins during development and to study metabolic interactions between plants and microbes.
