PHOTOSYNTHESIS AND STRESS,
September 2005 - Central European Conference organized by the
Department of Plant Physiology, Faculty of Science, Masaryk University,
Brno,. General Information
Research activity of the department in 2000 was realized mainly within the frame of several granted project: (1) Field and laboratory measurements of photosynthetic performance, water use efficiency, mycorrhizal infection, seasonal changes in nonstructural storage carbohydrates, and storage nitrogenous compounds were done on various plant species from alluvial mesophytic meadows near Lednice (South Moravia). The complex ecophysiological research was focused on explanation of competitive advantage of invading grass species (mainly Calamagrostis epigejos) and on prediction of changes in stand structure and function after the invasion. Laboratory experiments with plants grown in controlled conditions helped to a better understanding of interspecific differences in carbon and nitrogen use efficiency. (2) Effects of polycyclic aromatic hydrocarbons functioning of photosynthetic apparatus of model plants (Lactuca sativa, Allium cepa, Solanum lycopersicum) were studied using a combination of biochemical and biophysical approaches. Pronounced negative effect of photomodified fluoranthene on germination and early growth of the studied plants was detected by chlorophyll fluorescence technique. (3) Regulation of plant morphogenesis as regulated by phytohormones and growth regulators was studied. Mechanisms of modulation active cytokinin level were investigated by means of various transgenic constructs in Arabidopsis and tobacco plants. Embryo and seedling development were studied anatomically in the novel transcription activation system for regulated gene expression which was established at the Oxford University. The study is performed in close collaboration with the Laboratory of Plant Molecular Physiology, MU Brno and the Institute of Biophysics, Brno. (4) Detailed ecophysiological study of several foliose and fruticose macrolichens (mainly Lasallia pustulata, Hypogymnia physodes, Cetraria islandica, Umbilicaria antarctica) were made using fluorometric methods, optical microscopy and image analysis. Measurements of photosynthesis of the species in response to a wide range of temperature, high irradiance and thalus desiccation revealed interspecific differences which could be responsible for their in situ photosynthetic performance and selective distribution in the field. Isolation and cultivation of lichenized symbiotic alga Trebouxia sp. was done in order to obtain material for the study of high light stress in a lichen photobiont. (5) The effect of different concentrations of cadmium ions on growth and reproduction processes both in nucleocytoplasmic and chloroplast compartment of the cell was studied using synchronized cultures of the flagellate alga Chlamydomonas geitleri. It was revealed that among the targets of the metal inhibitory effect are cytoskeletal structures. The presence of cadmium ions causes also destruction of DNA containing structures in chloroplasts. Newly developed method of determination of the position of commitment points was proved to be very sensitive and fast for the study of the effect of heavy metals on the cell cycle.
