Regulation of central carbon metabolism in response to salinity stress. a Transcriptional regulation of central carbon metabolic pathways. Arrows in red, blue, and black indicate transcriptional up-, down-, and non-regulated steps. For proteins encoded by multiple copies of genes, the changes in total transcripts of the isogenes were employed for determining the overall regulation pattern. 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. Compounds are highlighted with different colors: red, significantly higher; black, not significantly changed; gray not determined; blue, significantly lower under upon salt stress.
