The BZ1 mutation influences biosynthesis of galactolipids and impairs photosynthesis efficiency and chlorophyll content. a Total lipid composition in leaves of wild-type (WT) and bz1 plants grown in paddy fields. SQDG, sulphoquinovosyl diglyceride; PC, phosphatidylcholine; PE, phosphatidylethanolamine; PG, phosphatidylglycerol; PS, phosphatidylserines; PI, phosphatidylinositol; PA, phosphatidic acids; TAG, triacylglycerols; DAG, diacylglycerols; CL, cardiolipins; FFA, free fatty acids. b Fatty acid composition of MGDG from WT and bz1 plant leaves. The results are means ± SE of five independent assays. c-d Detection of net photosynthetic rate (PN) (c) and chlorophyll content (d) of WT and bz1 at three developmental stages, more than 20 representative leaves were selected for measuring. *, ** and *** indicates significant differences between WT and bz1 by t-test at P < 0.05, 0.01 and 0.001, respectively
