Cell and developmental biology UP

The topics of our research team are: "Signal Networks and Cytoskeleton", "Development of Polarity in Plants" and "Interactions between Plants and Microorganisms", which are closely related to signal transduction cascades, cytoskeleton and endomembranes. Our team uses complex cell-biological, genetic, biotechnological, biochemical and proteomic approaches to better understand the molecular signalling in plants in relation to plant stress (both abiotic and biotic) physiology. In addition to exploring the relationships between the plant and its environment, we are currently also studying biotic interactions of model plants (Arabidopsis, alfalfa and barley) with some beneficial and pathogenic microorganisms. To study the interplay between mitogen-activated protein kinases (MAPKs) and cytoskeleton during plant development and stress adaptation, we use molecular biology and genetics methods and techniques (including CRISPR/Cas9 and various mutants) combined with advanced cell biology and microscopy (including super-resolution and light-sheet microscopy).

Born 1964; RNDr. in General Biology 1987, Comenius University in Bratislava; CSc. (PhD) in Plant Physiology 1993, Comenius University in Bratislava; habilitation in Botany 2004, Institute of Cellular and Molecular Botany, University of Bonn; DrSc. in Biology 2009, Slovak Academy of Sciences in Bratislava; Full Professor in Botany 2009, Palacký University in Olomouc.

Jozef Šamaj has long-term worked abroad, where he received prestigious post-doctoral scholarships at Universities in Toulouse (Eurosilva), Bonn (DAAD and Alexander von Humboldt Foundation) and Vienna (Marie Curie EU). He also worked as a senior researcher at the Institute of Genetics and Biotechnology of Plants of the Slovak Academy of Sciences for seven years, then as a group leader and Associate professor at the Institute of Cellular and Molecular Botany at the University of Bonn. Since 2010 he has been the head of the department and since 2017 also head of the section in the Centre of the Region Haná for Biotechnology and Agricultural Research of the Faculty of Science, Palacký University in Olomouc.

His research is focused on molecular and cell biology, biotechnology, proteomics, signalling, cytoskeleton, vesicular transport, endocytosis and plant stress (Arabidopsis, alfalfa, barley). He is editor of six books (including 5 in Springer), national representative of International Plant Proteomics Organization, member of several scientific societies and editorial boards of professional journals (WoS: 190 publications, 6000+ citations, h-index 43). He is teaching subjects Fundamentals of Cell and Developmental Biology and Molecular Cell Biology of Plants.

So far, Jozef Šamaj was the principal investigator of more than 10 research projects Vega, DAAD, AvH, DFG, GAČR and IGA UP (> 1.5 million €). At present, he is a scientific coordinator and program leader in the running ERDF project for Research Excellence, principal investigator of two standard GAČR projects and one bilateral AvH project.
