Abstract
The study revealed the results of the comparative analysis of the deoxyribonucleoproteid complex (chromatin) lipid composition in the callus and explant nuclei of plants, belonging to different systematic groups (winter rye, potatoes, peas). It provided the data on the phospho- and neutral lipid composition of the investigated plants and showed that the phospholipid content in the explants from dormant winter rye seed embryos and potato stems, having low metabolic activity, is significantly higher than in the calluses in the stage of active proliferation. Both winter rye and potato calluses tend to have a lower share of neutral lipids, including sterols, in their composition. The revealed factors can be used as markers of metabolic activity of the plant cell biology objects (callus and cell cultures).
