Climate change and thermal stress poses a problem for sustainable agriculture. Research in the adaptation and acclimation of plants to the elevated temperature is therefore one of the current scientific issues. Plants are exposed to different ambient temperatures during their life. The response to adverse temperatures includes a number of signalling pathways affecting development and growth processes in plants. Coordination of develomental processes under elevated temperature and other external factors is primarily controlled by plant hormones. Here effect of cytokinins on plant morphology, growth kinetics, gene expression and quanification in combination with increased temperature was observed. By determination of the hypocotyl growth during increased temperature, cytokinins were found to play important role in this process. Cytokinins were found to inhibit temperature induced hypocotyl growth and inversly seedlings treated with higher temperatutre showed decreased level of cytokinins which was confirmed on the level of marker gene expression and determination of levels of cytokinins.
