Regulation of TAG assembly in response to salt stress. a Transcriptional regulation of TAG assembly pathways. A heat map showing log2(fold change) values of gene transcripts. Significant difference (at least a twofold change and FDR adjusted p < 0.05) is indicated with an asterisk. Compounds are highlighted with different colors: red, significantly higher; black, not significantly changed; gray, not determined; blue, significantly lower upon salt stress. b Time-resolved expression of selected genes determined by qPCR. CLS caleosin, DAG diacylglycerol, DGAT Diacylglycerol acyltransferase, DGAT1 type I DGAT, DGTT type II DGAT, G3P glycerol-3-phosphate, GPAT glycerol-3-phosphate acyltransferase, LPA lysophosphatidic acid, LPAAT lysophosphatidic acid acyltransferase, MLDP major lipid droplet protein, PAP phosphatidate phosphatase, PDAT phospholipid:diacylglycerol acyltransferase, TAG triacyglycerol.
