Odpoveď ekotypov Arabidopsis na abiotický stres
 Zvalová, Monika
Distribution of a given plant species reflects its ability to acclimate to different natural environmental conditions. Plant acclimation to cold is of high importance because of recent raise of abundance of temperature extremes. The aim of this thesis was a characterization of twentytwo selected Arabidopsis ecotypes after sub-zero treatment and identification of those that are associated with effective cold acclimation. This evaluation of the processes involved in cold protection was enabled by substantial variability in the frost tolerance among these contrasting ecotypes. We identified frost tolerant and sensitive ecotypes that were further characterized by rosette area and photosynthetic pigments measurement. These results correspond with geographical distribution of a given species. The next step will be proteomic analysis of selected ecotypes to identified molecular processess involved in freezing stress tolerance. The adaptation of individual Arabidopsis ecotypes to different environmental conditions, resulting in a wide range of frost hardiness, offers unique possibility to elucidate mechanisms associated with efficient defence to low temperatures.Formula clause:I agree that my work will be published in accordance with § 47b of Act no. 111/1998 Coll., On Higher Education Institutions and on Amendments to Other Acts (Higher Education Act), as amended, and in accordance with the valid Directive on the Publishing of Higher Education Final Works
