Research Group
Cell Biology

Our research group studies plant cell biology. The focus is on abiotic stress tolerance that allowed plants to live on land. We combine different structural- and ultrastructural investigations with physiological, metabolic and transcriptomic analysis to understand plant resistance to unfavorable conditions dominating in early evolution of land plants. Our main research objects are green algae of the streptophytic lineage (sister clade to land plants), but we cover also the cell biology of other algae and higher plants from polar and alpine habitats.
