Abstract
The effect of 1 M NaCl on the lipid profile of detergent-resistant chloroplast membranes was studied. sts and mitochondria of salt-accumulating halophyte plants – Salicornia perennans Willd. And Suaeda salsa (L.) Pall. (family Amaranthaceae). The composition of lipids and fatty acids in detergent-resistant membranes differs from the membrane lipids of chloroplasts and mitochondria by a large number of cerebrosides and sterols. Under the given salinity conditions, S. perennans experienced many a fold increase in the proportion of cerebrosides in the composition of detergent-resistant chloroplast membranes, and in S. salsa is found in detergent-resistant mitochondrial membranes. The opposite effect was observed in relation to sterols: a decrease in their relative content under the action of salt. Received data indicate the participation of detergent-resistant membranes in the interaction of chloroplast cells and mitochondria in the cellular response of halophytes to salinity.
