Throughout their lifetime plants need to adapt to temperature changes. Plants adapt to nonfreezing cold temperatures in a process called cold priming (cold acclimation) and lose the acquired freezing tolerance during warmer temperatures through deacclimation. The alternation of both processes is essential for plants to achieve optimal fitness in response to different temperature conditions. Cold acclimation has been extensively studied, however, little is known about the regulation of deacclimation. This thesis elucidates the process of deacclimation on a physiological and molecular level in Arabidopsis thaliana. Electrolyte leakage measurements during cold acclimation and up to four days of deacclimation enabled the identification of four knockout mutants (hra1, lbd41, mbf1c and jub1) with a slower rate of deacclimation compared to the wild type. A transcriptomic study using RNA-Sequencing in A. thaliana Col-0, jub1 and mbf1c identified the importance of the inhibition of stress responsive and Jasmonate-ZIM-domain genes as well as the regulation of cell wall modifications during deacclimation.
