Appearance (Top) and lipid composition (Bottom) of Arabidopsis homozygous wild type and pho1, dgd1, and dgd1/pho1 mutant lines grown for 6 weeks on soil. Lipids were separated on activated ammonium sulfate-impregnated silica gel TLC plates and visualized with iodine vapor. The lipids were identified by cochromatography with lipid extracts of known composition. In addition, glycolipids were verified by specific staining with α-naphthol reagent. The numbers at the bands indicate the relative proportion (mol%) of the respective lipids. Abbreviations not mentioned in the legend to Fig. 1. PE, phosphatidylethanolamine; PG, phosphatidylglycerol; PI, phosphatidylinositol; SQDG, sulfoquinovosyldiacylglycerol.
