Abstract

Photosynthetic membranes of higher plants contain high amounts of galactolipids (monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG)) that are indispensable for the efficiency of photosynthetic light reactions. When plants are grown under phosphate-limiting conditions, phospholipids are partially replaced by galactolipids in plastidial and extraplastidial membranes, thereby releasing phosphate for other essential cellular processes.
