Overview of the trienoic fatty acid containing plastidic lipid remodelling strategies under high temperatures. Levels of non-bilayer forming MGDG are reduced and directed towards acyl-MGDG, DGDG, PC, TAG, TGDG, and oxylipins. Trienoic fatty acids from plastidic lipids are removed and transiently stored in TAG as lipid droplets. The figure showing the remodelling steps in reducing the unsaturated fatty acids from chloroplast lipids is modified from Higashi and Saito [63]. Abbreviations: FFA, free fatty acid; CoA—coenzyme A; 16:3, hexadecatrienoic acid; Gl-3-P, glyceraldehyde-3-phosphate; MGDG, monogalactosyl diacylglycerol; DGDG, digalactosyl diacylglycerol; SQDG, sulfoquinovosyl diacylglycerol; TGDG, trigalactosyl diacylglycerol; PG, phosphatidyl glycerol; PC, phosphatidyl choline; TAG, triacyl glycerol; MDA, malondialdehyde.
