Effects of low temperature on nuclear proteins of alfalfaKawczyński, Wojciech January 1995 (has links)
During the present studies we attempted to answer the following questions: (i) Does low temperature alter the phosphorylation level of proteins in isolated nuclei? (ii) Does the nuclear phosphoprotein population change during a prolonged exposure of seedlings to cold? (iii) Do heat-stable proteins accumulate in the nucleus during a prolonged exposure of seedlings to cold? (iv) Are the answers to the above three questions related to freezing tolerance? A possible relationship between the observed cold-induced changes in phosphoproteins and the level of freezing tolerance was explored by comparing the results of experiments conducted on two cultivars (Apica and Trek) of alfalfa (Medicago sativa L.) which markedly differ in their capacity for cold acclimation. / We show that the phosphorylation level of several nuclear proteins is subject to rapid and reversible enhancement by low temperature. Several phosphoproteins were found to be constitutively present in the nucleus of both cultivars. The cold-induced stimulation of the phosphorylation of many of these proteins was much greater in the relatively freezing tolerant cultivar Apica than in the relatively freezing sensitive cultivar Trek. Population of nuclear phosphoproteins was found to be considerably more complex in Apica than in Trek. During a prolonged exposure of the seedlings to 4$ sp circ$C, additional phosphoproteins were imported into the nucleus of Apica seedlings but not those Trek. / Some heat-stable proteins were constitutively present in the nucleus of both cultivars. However during the 4-day cold treatment, a large accumulation of several additional heat-stable proteins was observed in the tolerant, but not the sensitive, cultivar. (Abstract shortened by UMI.)
