Over-expression of the rice monogalactosyldiacylglycerol synthase gene(OsMGD)enhances tolerance to multiple stresses in tobacco
The galactoglycerolipids,monogalactosyldiacylglycerol and digalactosyldiacylglycerol(MGDG and DGDG,respectively)are the predominant membrane lipids in green plant tissues,and they constitute~75%of chloroplast lipids.In plants,MDGD biosynthesis is catalyzed by MGD synthase which transfers D-Gal from UDP-Gal to sn-1,2-diacylglycerol,and DGDG is synthesized by galactosylation of MGDG.Thus,MDG synthase is the key enzyme for the biosynthesis of galactolipids and,hence,construction of the plastid membranes.In the natural condition,plant growth is suffering various environmental stresses,and membranes in the plant cell become the major targets of these stresses.Regulation of membrane lipids property and composition are extremely important for plant to deal with such environmental stresses and make a considerable contribution for survival and adaptation.
