  • Plant Molecular Cell Biology - Prof. Dr. Wolfgang Frank


    Plants evolved specific mechanisms to adapt to extreme environmental conditions. We study these mechanisms at the molecular level to understand the underlying genetic, physiological and biochemical processes. Further, we concentrate on the function of non-coding RNAs that control gene expression via RNA interference. more

  • Plant Metabolism - Prof. Dr. Peter Geigenberger


    The central theme of my research is to investigate how plant metabolism is regulated and coordinated in response to environmental signals and how this affects growth, development and out-put traits in plants. To achieve this, we use a combination of systems biology and hypothesis driven approaches focussing on an integrated analysis (-omics profiling) of plant metabolism in different genotypes and environments. This includes genetic, biochemical and molecular-physiological methods. A further aim is to assess biotechnological applications to improve crops. In the context of the SFB-TR 175 B02, we explore the role of dynamic adjustments in photosynthetic metabolism of plants to acclimate to fluctuating light intensities and low temperatures. In the context of the DFG project Ge 878/7-2, we explore signalling components that are involved in the homeostatic response of plants to low oxygen concentrations. more

  • Plant Development - Prof. Dr. Andreas Klingl


    Protein localization studies in plant cells and plant pathogens as well as the ultrastructural characterization of microorganisms like the unicellular photosynthetic microalga Phaeodactylum tricornutum and extremophiles (hyperthermophiles, acidophiles) using electron microscopy represent the major research focus. Here as well as in education, the different microscopy and preparation techniques play an important role. more

    Our central research theme is the molecular dissection of photosynthesis and of its interdependence of, and integration into, other cellular processes - within and outside chloroplasts. Photosynthesis-relevant cellular functions and their regulation within the organelle and in cross-talk to the nucleus are characterised by a combined approach, complementing genetic, biochemical, physiological and molecular-biological methodology with system biology approaches. The plastid-wide characterization of protein functions, in particular for photosynthesis, and of networks imposed on their regulation, will result into the redesign of the photosynthetic process by synthetic biology and experimental evolution. more

    Plant cells are characterized by a high degree of compartmentation. Compared to other eukaryotes, plants possess additional compartments and organelles, e.g. chloroplasts where photosynthesis takes place. Our research focuses on the analysis of metabolic regulation and signalling within and between such cellular compartments. In particular, we are interested in resolving molecular strategies of plants to acclimate their compartments to fluctuating environmental factors, e.g. light or temperature. Such factors shape range boundaries of plant species and, hence, have a significant effect on plant evolution, development and ecology. Experimental approaches comprise measurement of rates of photosynthesis and respiration, enzyme activities and the subcellular proteome and metabolome. Mathematical modelling of metabolism allows us to computationally analyse the role of complex metabolic regulation in plant-environment interactions. more

  • Molecular Plant Science - Prof. Dr. Jörg Nickelsen


    During the phylogenetic development of the eukaryotic plant/algae cell, nowadays chloroplasts originated from former free-living cyanobacteria. The integration of this endosymbiont on a cellular level was achieved by the establishment of an intracellular communication system. This system is based on nucleus-encoded regulatory factors directing plastid gene expression especially on the posttranscriptional level including the assembly of functional multiprotein complexes. Understanding this regulatory network and its development on the molecular level is the main focus of our scientific work. more

  • Plant Biochemistry and Physiology - Prof. Dr. Jürgen Soll


    Protein and metabolite transport across membranes is an essential process in all kingdoms of life. We use plant chloroplasts as a model to understand the mechanisms and the regulation of protein import into an endosymbiotic organelle and metabolite exchange with the surrounding cell. To this end we apply a plethora of biochemical and molecular methods on a variety of organism such as cyanobacteria, pea and Arabidopsis thaliana. more

  • Molecular Cell Architecture and Trafficking - Prof. Dr. Ute C. Vothknecht


    Prof. Dr. Ute C. Vothknecht hast been appointed Professor for Plant Cell Biology at the University of Bonn.

    Interim acting Professor is PD Dr. Serena Schwenkert. more

  • Ultrastructural Research - Prof. Dr. Gerhard Wanner


    The Ultrastructural Research group investigates a broad spectrum of topics using transmission electron microscopy and high resolution scanning electron microscopy in combination with many analytical methods and cryo-techniques. Working over the years in numerous national and international cooperations, research topics have ranged from the biogenesis of organelles, compartmentalization of secondary metabolites in plant and animal cells, the accumulation of heavy metals in bacteria and cell cultures, up to the localization of protein molecules in/on cells or cell structures. more
