title: [Incorporation of 32P into membrane phospholipids during chloroplast biogenesis].
abstract: The composition of membrane phospholipids during chloroplast biogenesis was studied. The maximal level of phosphatidic acid was observed in the membrane fraction of proplastids. Phosphatidylglycerol was found to be the most abundant phospholipid component of grana thylakoids. The evidence from the in vivo experiments indicates that phosphatidic acid and phosphatidylglycerol incorporate the 32P label at a high rate at all stages of the chloroplast biogenesis. It is concluded that plastids are the site of the phosphatidylglycerol biosynthesis in the plant cell.
