Laboratory of Physiology of Photosynthesis

Laboratory of Stress Physiology Field of research | Workers Grants | Selection of recent publications

Field of research

The research of the laboratory is focused on plant responses to different environmental stresses (especially those connecting with climate global change: elevated CO₂ concentration, water stress, and UV-radiation, and on high irradiance and chilling stress) and to biotic stresses (ageing, high content of endogenous cytokinins, viral infection) acting individually or in different combinations.

The changes in physiological and structural characteristics are determined on the level of whole leaves and plants, cellular, or subcellular level. We determine parameters of gas exchange, water regime, structure and function of photosynthetic apparatus and other cell organelles, development of reactive oxygen species, oxidative damage and induction of biosynthesis of protecting pigments and antioxidants.

Not only immediate response to environmental factors are followed but also acclimations and de-acclimations to stresses and after their relief.

Important direction of our research is to determine the effect of phytohormones abscisic acid and cytokinins (endogenous content and/or application) on plant responses to stresses.
