Fatty acid composition of glycolipids in Arabidopsis galactolipid mutants expressing Chloroflexus GlcT

Fatty acid composition of glycolipids was determined by TLC and GC of fatty acid methyl esters. Values are given in mol % and indicate means of three measurements. sd was always below 2.5 mol %. n.d., Not detected (below 0.5%). Note that the lines dgd1dgd2 and dgd1dgd2GlcT do not contain DGD, while the wild type, dgd1, and dgd2 are devoid of GGD.
