Abstract

For the first time, the composition and seasonal changes of dehydrins in shoots of Siberian spruce (Picea obovata Ledeb.) under conditions of the cryolithic zone of Central Yakutia were studied. It is shown that most of the major dehydrins (57–17 kDa) are represented P. obovata relatively evenly throughout the year, which indicates their constitutive properties. In contrast, low molecular weight dehydrins (15 and 13 kDa) are inducible proteins: they disappear in the summer months and reappear in the autumn in the period of cold adaptation.
