Lipid class profiles of purified mitochondria and total leaf extracts. Glycerolipids of leaf total extract (L-TE) and mitochondria isolated from leaves (L-mito) were analyzed by a TLC–GC/FID approach. Data of L-TE represent mean values in mol % from three independent experiments; data of L-mito represent mean values in mol % from two of the three independent experiments. PC, phosphatidylcholine; PE, phosphatidylethanolamine; CL, cardiolipin; PG, phosphatidylglycerol; MGDG, monogalactosyldiacylglycerol; DGDG, digalactosyldiacylglycerol.
