The Department comprises 2 Research Teams: Regulation of Gene Expression and Plant Molecular Physiology and Cytogenetics. Research concentrates on mechanisms of plant adaptation to changing environmental conditions during the vegetative and generative phase of growth. The main aim of the studies is to understand the molecular and physiological basis of plant adaptation mechanisms to low temperature, water scarcity, and salinity. The integrated research is performed on crops, including potato (Solanum tuberosum), ryegrass (Lolium) and fescue (Festuca) species, Lolium-Festuca hybrids, and oilseed rape (Brassica napus var. oleifera).
Research profiles
  • signal transduction pathways,
  • identification of genes functioning at different stages of plant response to stress factors based on the transcriptome and proteome analysis and using of mutants corresponding to the genes,
  • activation mechanisms of transcriptional regulators and expression of their target genes, determination of protein-protein and protein-DNA functions in vitro and in planta,
  • identification of stress responsive genes in plant chromosomes, regulation of gene expression at the level of chromatin complex,
  • physiological aspects of stress response: changes in osmotic potential, stomatal and hydraulic conductance, photosynthetic rate, membrane integrity and the efficiency of antioxidant system,
  • plant cellular metabolism under stress conditions and after stress cessation, including primary metabolites and membrane lipids.
