The Department of Experimental Plant Biology provides education in the Experimental Plant Biology Master’s programme and the Doctoral programme of Plant Physiology. The research topics cover environmental plant physiology, biochemistry and the biophysics of photosynthesis and plant-water relations, and are focused on several dominant areas.
The regulation of photosynthesis in higher plants, algae, and cyanobacteria is studied on a molecular, cellular and organ level, with respect to environmentally important natural variability of CO2 concentration, temperature, irradiance and nutrients. In higher plants, leaf internal limitations to CO2 fixation (mesophyll conductance for CO2) are studied using gas exchange, chlorophyll fluorescence and stable isotope mass spectrometry techniques.

Environmental factors controlling stomatal development and patterning in leaf epidermis are studied using gas exchange, thermography, mass spectrometry, and microscopy. Transport and structural properties of the cuticle as a leaf water loss barrier are studied in cooperation with the Institute of Cellular and Molecular Botany, University of Bonn.

Fractionation of water isotopes (18O and D) in the soil–plant–atmosphere continuum and stable carbon isotopes (13C/12C) in leaves and stems (tree rings) is applied in the assessment of plant growth conditions, water use and in the tracing of the geographical origin of plant products. In cooperation with Technical University Munich (Chair of Grassland Science, Freising), we organize the International Spring School on Stable Isotopes in Environmental Sciences, Ecology and Physiology (https://isotopeschool.wzw.tum.de/).
Bryophytes, the earliest land plants, thrive through a huge range of environmental conditions. Their physiological adaptations are studied with respect to their ecology in extreme habitats, typically under stress from limiting or excess availability of water, mineral nutrients and photosynthetic light. Ecophysiology of peat mosses (Sphagnum) is of special interest.

A highly collaborative, interdisciplinary approach that combines biophysical, analytical, molecular biology and computational methods is used to investigate molecular mechanisms behind the adaptation of photosynthesis to ambient temperature. The discovered stabilization mechanisms are being exploited together with our partner team at Weizmann Institute of Science in engineering of thermotolerant strains of algae while mutagenesis studies on tobacco are performed at our University. Thermal adaptation of photosynthesis in cryotolerant algae and thermotolerant photosynthetic bacteria is carried out in collaboration with teams at the Institute of Microbiology CAS.

Many metals are essential for all organisms as active centres of enzymes and other proteins, but in higher concentrations they become toxic. Metal deficiency as well as metal toxicity frequently occurs in many parts of the world, incl.
