Technical Abstract: The effect of methyl jasmonate (MJ) on changes in membrane lipid composition and activities of oxygen scavenging enzymes under water stress was studied in strawberry leaves. Under water stress, MJ treatment reduced transpiration, water loss, malondialdehyde (MDA) content and also decreased the reduction of membrane lipids, galactolipids [monogalactosyl diglyceride (MGDG) and digalactosyl diglyceride (DGDG)], phospholipids [phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), and phosphatidylinositol (PI)], and ratio of fatty acid linolenic (18:3) to linoleic acid (18:2). Higher activities of catalase, peroxidase, superoxide dismutase and glutathione reductase were detected in the MJ-treated leaves compared to control leaves under water deficit conditions. These results indicate that MJ treated plants are more resistant to water stress.
