The long-term goal of my research is a deep systemic understanding of specific cellular metabolite damage control systems in land plants and algae. Furthermore, we strive to provide basis for the development and implementation of strategies to improve organisms in terms of efficient resource utilization and enhanced yield. To achieve these goals, my group combines extensive expertise in plant physiology, biochemistry, and molecular biology into a vigorous, interdisciplinary research program.

Spontaneous reactions of metabolites and side reactions of enzymes will inevitably lead to the formation of toxic by-products. Accumulation of those toxic metabolites needs to be tightly controlled to prevent cellular damage. Therefore, metabolite repair pathways must not only detoxify unwanted products fast and efficiently, but must also keep energetic loss for the organism as small as possible. Current research is focused on the biochemical properties and physiological significance of two distinct metabolite repair pathways: (1) the Glyoxalase System, found in nearly all domains of life, and (2) the Photorespiratory Cycle, unique for phototrophic organisms.

Lysine acetylation is a post-translational modification involved in the regulation of several enzymes of plant metabolism, and the most abundant modification in mitochondrial proteins. The mitochondrial acetylome of A. thaliana showed acetylation in two key enzymes of malate metabolism: malate dehydrogenase and malic enzyme. My current research is dedicated to analyze the acetylation of these enzymes in vitro, and determine the influence of this modification on their kinetic, regulatory and structural properties.

In their natural habitats, plants are rarely to be subjected to a single stress. My project introduces a more complex experimental design of a multi-stress condition that mimics arid environments, where plants, simultaneously, experience a combination of drought, high temperature and salt stresses. The plant response to single, double and triple combinations of these abiotic stresses are investigated at the molecular and physiological levels. The work is extended to study the plant susceptibility when these stresses are joined with different pathogen attacks.

Current projects focus on (1) C4 photosynthesis and how the NAD-dependent malic enzyme of C4 plants differs from its C3 counterparts using different species of the Cleome genus. Also, I work on the identification and functional significance of posttranslational modifications that may occur in these enzymes. (2) To understand function and regulation of malate respiring enzymes in mitochondria in more detail, I utilize a combination of reverse genetic, physiological and biochemical approaches in the model plant Arabidopsis thaliana.

In my PhD project, I am working on the post-translational regulation and structural characterization of major C4 proteins. Specifically, I am assessing the significance of identified post-translational modifications of the photosynthetic maize NADP-malic enzyme in vitro (heterologous protein production and kinetics studies) and in vivo studies (using antibodies specific to the identified PTMs).

In my Master thesis, I am characterizing the enzymes of the Glyoxalase system. Hereby, I am analyzing T-DNA lines and CRISPR/Cas9 generated loss-of-function lines. Furthermore, I am determining the influence of methylglyoxal, the major substrate of the Glyoxalase system, on the intracellular glutathione levels.

The NAD-dependent malic enzyme and the mitochondrial malate dehydrogenase are well known for their key roles in the TCA cycle of plants. The topic of my bachelor thesis is the contribution of these enzymes to malate metabolism in mutant lines of A. thaliana. It includes a phenotypical characterisation of three mutant lines and their comparison to other mutants. To study the main metabolic changes occuring as consequences of the different loss-of-function lines, changes in expression and metabolic abundunces among plant lines are compared.
