Expression profiles of genes including homologues in the triacylglycerol assembly pathway. The dash line at 6.0 is often used as the cutoff for present (expressed; above the line) or absent (unexpressed; below the line). All expression data were transformed to the log2 scale for plotting the profiles. Genes and homologs in the triacylglycerol (TAG) assembly pathway were identified based on an early survey of Arabidopsis genes involved in acyl lipid metabolism , and their AGI identifiers listed in Additional File 3. Refer to  for their roles in TAG assembly. The abbreviations of these genes and their encoded enzymes (EC numbers) are as follows: GPAT: sn-glycerol-3-phospahte acyltransferase (EC 22.214.171.124); LPAAT: lysophosphatidic acid acyltransferase (EC 126.96.36.199); PAP: PA phosphatase (EC 188.8.131.52), including LIPIN (PAP1) and LPP (PAP2); AAPT: Aminoalcoholphosphotransferases (EC 184.108.40.206 and EC 220.127.116.11); CPT: cytidine diphosphate (CDP)-choline: 1, 2-diacylglycerol cholinephosphotransferase (EC 18.104.22.168); LPCAT: lysophosphatidylcholine acyltransferase (EC 22.214.171.124); PLA2: Phospholipase A2 (EC 126.96.36.199); PDAT: phospholipid:diacylglycerol acyltransferase (EC 188.8.131.52); LCAT: lechitin:cholesterol acyltransferase (EC 184.108.40.206), these three shown here are PDAT homologs; DGAT: Diacylglycerol acyltransferase (E.C. 220.127.116.11).
