disruption of the two digalactosyldiacylglycerol synthase genes DGD1 and DGD2 in Arabidopsis reveals the existence of an additional enzyme of galactolipid synthesis
UDP-galactose + monogalactosyldiacylglycerol
DGD2 seems to act preferentially on monogalactosyldiacylglycerol molecular species with 16-carbon fatty acids in the sn-1 position and on 18-carbon fatty acid in the sn-2 position in vivo

DGD2 mRNA expression in leaves is very low but is strongly induced during growth under phosphate-limiting conditions
UDP-galactose + monogalactosyldiacylglycerol
DGD1 seems to act preferentially on monogalactosyldiacylglycerol molecular species with 18-carbon fatty acids in the two positions of monogalactosyldiacylglycerol in vivo

a null-mutant of Arabidopsis, which lacks the DGDG synthase (DGD1) resulting in a 90% reduction in the amount of DGDG under normal growth conditions, accumulates digalactosyldiacylglycerol after phosphate deprivation up to 60% of the amount present in the wild-type. Extraplastidic biosynthesis of digalactosyldiacylglycerol induced by phosphate deprivation is a biochemical mechanism for plants to conserve phosphate
