Cover Story: The aim was to characterize disturbances in the hormonal balance and in the accumulation of heat shock proteins (HSP) as a result of deacclimation of oilseed rape. Samples were collected from plants that had not been acclimated, cold acclimated (4 °C d/n, three weeks), and deacclimated (16/9 °C d/n, one week). The tested hormones included—among others—abscisic acid, gibberellins, and auxins. A concentration of ABA increased in all tested cultivars during cold acclimation and strongly decreased during deacclimation. Deacclimation resulted in elevated level of growth hormones. Cold acclimation increased the accumulation of cytoplasmic HSP70 in three of the four tested cultivars, while it often decreased in the deacclimated plants. View this paper
