| Lipid | Wild Type | tgd1-1 |
|---|---|---|
| MGDG | 43.0 ± 1.8 | 39.6 ± 0.3 |
| PG | 10.4 ± 0.1 | 12.6 ± 0.1 |
| DGDG | 18.2 ± 0.4 | 12.9 ± 0.5 |
| SQDG | 2.3 ± 0.2 | 3.4 ± 0.7 |
| PI | 1.2 ± 0.1 | 1.7 ± 0.2 |
| PE | 10.0 ± 0.6 | 11.0 ± 0.4 |
| PC | 15.1 ± 1.4 | 16.8 ± 1.2 |
| TGDG | n.d. | 1.4 ± 0.2 |
PA could not be separated by linear TLC used for this experiment and had to be analyzed by two-dimensional TLC. Values represent mol % ± se of fatty acid methylesters derived from individual lipids. n.d., not detected. PE, phosphatidylethanolamine; PG, phosphatidylglycerol; PI, phosphatidylinositol; SQDG, sulfoquinovosyldiacylglycerol.
