Differential expression of genes involved in (A) the fatty acid biosynthesis; (B) triacylglycerol biosynthesis; (C) β-oxidation; and (D) starch biosynthesis. Pathway were reconstructed based on the de novo assembly and quantitative annotation of the N. oleoabundans transcriptome. (A) Enzymes include: ACC, acetyl-CoA carboxylase (EC:; MAT, malonyl-CoA ACP transacylase (EC:; KAS, beta-ketoacyl-ACP synthase (KAS I, EC:; KASII, EC:; KAS III, EC:; KAR, beta-ketoacyl-ACP reductase (EC:; HAD, beta-hydroxyacyl-ACP dehydrase (EC: 4.2.1.-); EAR, enoyl-ACP reductase (EC:; AAD, acyl-ACP desaturase (EC:; OAH, oleoyl-ACP hydrolase (EC:; FatA, Acyl-ACP thioesterase A (EC: 3.1.2.-); Δ12D, Δ126)-desaturase (EC:; Δ15D, Δ153)-desaturase (EC: 1.4.19.-); (B) Enzymes include: GK, glycerol kinase (EC:; GPAT, glycerol-3-phosphate O-acyltransferase (EC:; AGPAT, 1-acyl-sn-glycerol-3-phosphate O-acyltransferase (EC:; PP, phosphatidate phosphatase (EC:; DGAT, diacylglycerol O-acyltransferase (EC:; and PDAT, phopholipid:diacyglycerol acyltransferase (EC; (C) Enzymes include: ACS, acyl-CoA synthetase (EC:; ACOX1, acyl-CoA oxidase (EC:; ECH, enoly-CoA hydratase (EC:; HADH, 3-hydroxyacyl-CoA dehydrogenase (EC:; ACAT, acetyl-CoA C-acetyltransferase (EC:,; (D) Enzymes include: PGM, phosphoglucomutase (EC:; AGPase, ADP-glucose pyrophosphorylase (EC:; SS, starch synthase (EC:; BE, α-1,4-glucan branching enzyme (EC:; and HXK, hexokinase ( Starch catabolism enzymes include: α-AMY, α-amylase (EC:; O1,6G, oligo-1,6-glucosidase (EC:; β-AMY, β-amylase (EC:; and SPase, starch phosphorylase (EC: Ethanol fermentation via pyruvate enzymes include: PDC, pyruvate decarboxylase (EC:; and ADH, alcohol dehydrogenase (EC: Enzymes aceE, pyruvate dehydrogenase E1 component (EC; aceF, pyruvate dehydrogenase E2 component (EC:; and pdhD, dihydrolipoamide dehydrogenase (EC, transforms pyruvate into acetyl-CoA. Key enzymes are shown with an asterisk (*) next to the enzyme abbreviations, and dashed arrows denote reaction(s) for which the enzymes are not shown. All presented fold changes are statistically significant, q value < 0.05.
