Relative expression levels of genes related to photosynthesis, lipid and NADPH biosynthesis in overexpression lines (OE1 and OE2) and wild-type (WT). a–d Photosynthetic related genes including ATPase gamma subunit (AtpC), oxygen-evolving enhancer protein (PsbO), photosystem II subunit (PsbM) and cytochrome c6 (PetJ); e–m TAG biosynthetic related genes including glycerol-3-phosphate acyltransferase 2 (GPAT2), glycerol-3-phosphate acyltransferase 3 (GPAT3), lysophosphatidyl acyltransferase 2 (LPAT2), lysophosphatidyl acyltransferase 3 (LPAT3), phosphatidic acid phosphatase (PAP), diacylglycerol acyltransferase 1 (DGAT1), diacylglycerol acyltransferase 2A (DGAT2A), diacylglycerol acyltransferase 2B (DGAT2B) and diacylglycerol acyltransferase 2D (DGAT2D); n, o NADPH biosynthetic related genes including malic enzyme (ME) and glucose-6-phosphate dehydrogenase (G6PD); p MGD, a monogalactosyldiacylglycerol synthase gene. Each value represents the mean ± SD (n = 3). The gene information and primers are shown in Additional file 1: Table S1. Each value represents the mean ± SD (n = 3)
