Diglycosyldiacylglycerol synthesis and transport in DGD-deficient and GlcT-expressing lines. Synthesis of DGD and GGD in the wild type and GlcT-expressing lines, respectively, is localized to the envelope membranes. During phosphate deprivation, DGD and GGD accumulate in the chloroplast membranes. Furthermore, DGD and GGD are exported to extraplastidial membranes. Glc and Gal are depicted as gray and white hexagons, respectively, and the diacylglycerol moiety of galactolipids is depicted as a vertical line with two wavy horizontal lines.
