Current projects
Plants face many environmental challenges such as nutrient availability, light conditions, abiotic and biotic stresses. These factors greatly influence resource allocation and thus plant productivity. Plants use manifold sensing, signalling and response mechanisms to achieve a fine balancing act in the face of these challenges. The regulatory mechanisms involved have to be co-ordinated with developmental programmes as well as cell and tissue specific requirements. Cross-talk of signalling mechanisms and sharing of signalling components suggests the general principle that signalling pathways operate as complex networks rather than isolated, independent cascades We are trying to identify and to understand these mechanisms in the quest to improve crop productivity in a sustainable fashion.

A class of plant proteins encoded by the so-called '14-3-3' gene family are considered key players in bringing various sensing, signalling and response pathways together. 14-3-3 proteins interact with and regulate the activity of key enzymes in plant nitrogen and carbohydrate metabolism. These interactions influence enzyme activity at critical steps in primary metabolism and thus alter plant resource allocation on a global scale.
We have isolated a collection of T-DNA knock-out lines with single mutations in a number of 14-3-3 genes. Initially, we are studying the regulation of carbohydrate and nitrogen metabolism and the allocation of resources in these mutants under consideration of metabolic and developmental aspects. To achieve this, we are employing classical molecular, genetic and biochemical techniques in combination with metabolomics and functional genomics technologies. We are identifying specific 14-3-3 isoforms involved in defined regulatory processes such as for example the regulation of nitrate reductase.

Our aims are to:
- Identify specific 14-3-3 isoforms involved in the regulation of enzymes of carbohydrate and nitrogen metabolism
- Study the impact of 14-3-3 mutations on these metabolic pathways and the subsequent distribution and allocation of resources and storage compounds.
- Investigate the signalling mechanisms leading to 14-3-3 regulation of carbon and nitrogen metabolism
