Science and research

 

Teams of the Department of Experimental Plant Biology

Plant Cell Biology and Biotechnology

The Dr Kateřina Schwarzerová group investigates plant cytoskeleton at the molecular and cellular level. The research contributes to understanding the role of the cytoskeleton in plant morphogenesis and signalling. Dr Lukáš Fischer group is focused on RNA interference (transgene silencing), G-protein signalling and the role of the mangan-stabilizing protein of the photosystem II. Dr Jan Petrášek group is particularly focused on auxin transport and the role of the cytoskeleton in auxin-directed plant development.

Cell Morphogenesis

The group of Ass. Prof. Fatima Cvrčková and Ass. Prof. Viktor Žárský is focused predominantly on the molecular mechanisms of cell polarity. The group researches proteins and protein complexes involved in polarised exocytosis and organisation of the cytoskeleton (particularly the multiprotein complex Exocyst and the cytoskeleton-organising formin family). The group also investigates the signalling pathways coordinating cell polarity establishment. Part of the team is located at the Institute of Experimental Botany AS CR.

 

Cell growth and differentiation,

The laboratory of Matyáš Fendrych aims to reveal the molecular and physiological processes that govern the growth of plant cells and organs. In the focus of our research lies the intriguing plasma membrane-cell wall interface that is crucial for perception and regulation of the cell wall properties. We study the mechanisms of growth regulation and coordination on the supra-cellular scale during the development and differentiation of plant organs. We use the Arabidopsis thaliana model system, and we combine molecular biology tools with advanced live-cell imaging, genetically encoded fluorescence sensors, specialised vertical microscopy and microfluidic techniques

Ecophysiological Anatomy

The Prof. Jana Albrechtová group investigates plant physiological and structural reactions to the biotic and abiotic environmental factors. The research is focused mainly on the ecophysiology of woodplants and exploits a wide array of methods: microscopy, histochemistry, biochemistry, spectral analysis of leaves that can also be used in remote sensing of the Earth. The group contributes significantly to the improvement of quantitative methods in plant anatomy.

Physiological Anatomy

The Dr Aleš Soukup group is focused on the development, function and interactions of the root system with the soil environment. The „classical anatomy“ approach is enriched by cytology, biochemical analyses and molecular biology. Such combination enables to connect structural and functional parameters of the plant body that are changing during tissue differentiation, plant ontogenesis or during changes of the external environment.

Plant Morphogenesis Regulatory Factors

The group of Ass. Prof. Helena Lipavská is interested in plant sugar metabolism connected with developmental changes and heavy metal, cold, drought stress etc. Further interest is focused on the developmental changes of plants transfected with allosteric mitotic aktivátor. The group also investigates the plant-fungi interaction in the life cycle of orchids. Along with traditional cultivation methods, the group contributes to the improvement of in vitro cultivation methods for plant explantates.
