Synthesis and turnover of triacylglycerol in leaves of the wild type (WT) and dgat1 and pdat1 mutants. Incorporation of [¹⁴C]fatty acids into triacylglycerols (A), diacylglycerol (B), and phosphatidylcholine (C) in Arabidopsis WT and pdat1 and dgat1 mutants. The dotted line represents the end of the pulse period and the beginning of the chase period. The inset graph presents the percentage of WT incorporation after 60min of labelling. The data represent the average of three biological replicates. Additional data including all identified glycerolipids and free fatty acids with error bars are presented in Supplementar Fig. S2 at JXB online. (Figure 1 is available in colour at JXB online.)
