Regulation of membrane glycerolipid synthesis in response to salt stress. a Transcriptional regulation of membrane lipid biosynthetic pathways. Arrows in red and black indicate transcriptional up- and non-regulated steps, respectively. For proteins encoded by multiple gene copies, the changes in total transcripts of the isogenes were employed for determining the overall regulation pattern. Compounds are highlighted with different colors: red, significantly higher; black, not significantly changed; gray, not determined; blue, significantly lower upon salt stress. b Heat map showing log2(fold change) values of gene transcripts. Significant difference (at least a twofold change and FDR adjusted pā€‰<ā€‰0.05) is indicated with an asterisk.
