ABSTRACT
MAIN CONCLUSION:
The comparison of the changes of the lipid content in plant cell boundary membranes demonstrates a substantial role of the vacuolar membrane in response to hyperosmotic stress. Comparison of variations in the lipid content of plant cell boundary membranes (vacuolar and plasma membranes) isolated from beet root tissues (Beta vulgaris L.) was conducted after the effect of hyperosmotic stress. Both types of membranes participate in the formation of protective mechanisms, but the role of the vacuolar membrane was considered as more essential. This conclusion was connected with more significant adaptive variations in the content and composition of sterols and fatty acids in the vacuolar membrane (although some of the adaptive variations, especially, in the composition of phospholipids and glycoglycerolipids were similar for both types of membranes). In the plasma membrane under hyperosmotic stress, the increase in the content of sphingolipids was noted that was not observed in the tonoplast.Palavras-chave
