Heatmap plots of genes of fatty acid biosynthesis pathway C. oleifera. The number in parentheses means the number of unigenes encoding these enzymes, which had a total RPKM value over 20. Plastid FA synthesis in the upper part (a); ER FA modification, acyl editing and TAG assembly in the lower part (b). The red boxes are the enzymes related to FA synthesis; the yellow boxes are the enzymes related to FA modification and acyl editing; the purple boxes are the enzymes related to TAG assembly. acyl-CoA: diacylglycerol (DAG) (1) was de novo synthesized DAG, and DAG (2) was PC-derived DAG. Data for the relative expression levels of genes were obtained by using the log2 of RPKM values. Abbreviations: ACCase, acetyl-CoA carboxylase; ACP, acyl carrier protein; DAG, diacylglycerol; DGAT, acyl-CoA:DAG acyltransferase; FabD, malonyl CoA:ACP transacylase; FabF, β-ketoacyl-ACP synthase; FabG, β-ketoacyl-ACP reductase; FabH, acetyl CoA:ACP transacylase; FabI and FabK, enoyl-ACP reductase; FabZ, β-hydroxyacyl ACP dehydrase; FAD2, fatty acid desaturase 2 (Δ-12 desaturase); FAD3, FAD7 and FAD8, Δ-15 desaturase; FAD6, fatty acid desaturase 6 (Δ-12 desaturase); FatA and FatB, acyl-ACP thioesterase; FFA, free fatty acid; G3P, glycerol-3-phosphate; GPAT, acyl-CoA:G3P acyltransferase; LACS, long chain acyl-CoA synthetase; LPA, lyso-phosphatidic acid; LPAAT, acyl-CoA:LPA acyltransferase; LPCAT, acyl-CoA:lysophosphatidylcholine acyltransferase; PA, phosphatidic acid; PAP, PA phosphatase; PC, phosphatidylcholine; PDAT, phospholipid:diacylglycerol acyltransferase; PDCT, PC:DAG cholinephosphotransferase; PLC, phospholipase C; PLD, phospholipase D. PUFA, polyunsaturated fatty acid; SAD, stearoyl-ACP desaturase (Δ-9 desaturase); TAG, triacylglycerol; ER, endoplasmic reticulum.
