Abstract

The effect of NaCl on the lipid profile of microdomains of chloroplast and mitochondria membranes of euhalophyte plants was studied. It was found that during salinization of the medium, the main changes among raft-specific lipids are associated with an increase in the relative content of sphingolipids (cerebrosides). The data obtained indicate the participation of microdomains of intracellular membranes in the adaptation of halophytes to soil salinization.
