Department of Plant Physiology
The research activities of the Department of Plant Physiology are focused on the processes involved in root cell morphogenesis and structural and physiological responses of plants to stressful conditions. The study of abiotic stresses, especially metal toxicity (Al, Zn, Ni, Cd) are directed to the areas such as metal interactions with the cytoskeletal components, signal transduction process (e.g. MAP kinases), spatiotemporal pattering of ROS and oxidative damages and the expression and activity of ROS-generating enzymes together with induction of specific genes responsible for antioxidative defence in the different parts of root tips. The research on biochemical and physiological aspects of drought tolerance and salinity are concentrated on adaptive responses of plants to drought. Microscopic, immunoflourescene and molecular biology techniques are promising approaches to understanding the mechanism of plant resistance to stressful conditions. Economically important plant species e.g. Brassica napus, Hordeum vulgare, Vicia sativa, Zea mays, as well as some model plants (Arabidopsis thaliana, Lotus japonicus) are used as experimental material. Our effort is partially directed also on the impact of toxigenic fungi ( Aspergilus, Penicilium, Alternaria and Fusarium spp.) and their products – mycotoxins on the life cycle of host plants and disease control.
The Department´s research activities are realized in well equipped laboratories (laboratory of abiotic stresses, laboratory of plant physiology, laboratory of electrophysiology, laboratory of light and fluorescence microscopy and laboratory of molecular biology) in collaboration with leading laboratories in abroad (University of Bristol, UK, University of Bonn, Germany, University of Vienna, Austria, University of Seville, Spain, University of Barcelona, Spain, ISPA/CNR Bari, Italia).
