title: Relationship between fatty-acyl composition of diacylgalactosylglycerol and turnover of chloroplast phosphatidate.
abstract: Chloroplasts from plants that contain different proportions of the 2-hexadecatrienoyl-1-linolenoyl molecular species in total diacylgalactosylglycerol were examined for their ability to dephosphorylate phosphatidate that had been labelled in situ with [1-14C]acetate. The turnover rate of chloroplast phosphatidate may be related to the accumulation of a prokaryotic diacylgalactosylglycerol, suggesting that chloroplast phosphatidate phosphatase controls the fatty acyl composition of the diacylgalactosylglycerol synthesized in the intact plant.
