Fig. 6

Schematic diagram representing palmitoleic acid biosynthesis and TAG accumulation in SBP. The bold arrows in red indicate the metabolic flux from C16:0-ACP to C16:1n7-TAG. The red (upregulation) and green (downregulation) boxes indicate the key genes in C16:1 biosynthesis and its accumulation in TAG. The violet arrows indicate the Kennedy pathways in TAG assembly. The blue arrows indicate the phosphatidylcholine acyl pathways in TAG assembly. The enzymes are shown in boxes and abbreviated as follow: ACC, acetyl-CoA carboxylase; KAS, 3-ketoacyl-ACP synthase (KAS I, KAS II, KAS III); KAR, 3-ketoacyl-ACP reductase; HAD, β-hydroxyacyl-ACP dehydrase; EAR, enoyl-ACP reductase; FATA, acyl-ACP thioesterase A; FATB, acyl-ACP thioesterase B; Δ9D, delta-9 desaturase; FAE1, fatty acid elongation 1; FAD2, fatty acid desaturase 2; FAD3, fatty acid desaturase 3; GPD1, glycerol-3-phosphate dehydrogenase; GPAT, glycerol-3-phosphate O-acyltransferase; LPAT, lysophosphatidic acid acyltransferase; LPIN, phosphatidate phosphatase; DGAT, diacylglycerol O-acyltransferase; plcC, phospholipase C; PDAT, phopholipid:diacyglycerol acyltransferase. The names of key intermediates are abbreviated as follows: G3P, glycerol-3-phosphate; LPA, lysophosphatidic acid; PA, phosphatidic acid; DAG, diacylglycerol; TAG, triacylglycerol
