The group around Stefanie Wienkoop is dealing with the systemic analysis of plants. To gain insight into plant systems, the research group focus on the crosslinking between metabolic networks using mass spectrometry (metabolomics and proteomics) as a major tool.

One central topic is the comparative analysis of different abiotic and allelopathic stress factors in legumes such as Lotus japonicus, Medicago truncatula, Garden- and Soybean as well as Pea.

Biological questions are the interaction, regulation and adaptation of metabolic networks and growth processes of different plant tissues (leaf, root, nodule) to unravel the influence of changing environmental conditions also in respect to symbiotic plant-microbe interactions.

Environmental changes and interferences are affecting a complex metabolic network thus influencing the interaction of a whole system.

Plants are sessile life forms that have to adapt to these continuously changing environmental conditions. Those changes can be caused due to diurnal rhythm and abiotic factors such as temperature, light, water and nutrition supply. Plants are considered stressed if reduction in growth or reproduction is caused dependent upon load. Applications of targeted and non-targeted analyses are being used. The non-targeted approach allows for the comprehensive and unbiased analysis of metabolic pathways, which enables detection of novel physiologicallyrelevant metabolites and proteins that uncovers new regulatory mechanisms and complex network connections. The complementary targeted analysis allows for the determination of absolute concentrations the study on subcellular localisation, post translational modifications etc. of selected metabolites and proteins belonging to an interacting metabolic pathway.
