The proportions of differentially expressed transcription factor encoding genes in leaves and roots under different salinity contrasts (0 mM vs 250 mM NaCl and 250 mM vs 500 mM NaCl). Orange dashed line represents the proportion of transcription factor encoding genes in the whole S. alba genome. Red bars represent the proportion of differentially expressed TFs among all DEGs. Gray bars represent the proportion of TFs among up-regulated genes. Orange bars represent the proportion of TFs among down-regulated genes. Fisher’s exact test was used to evaluate the significance of the differences between the proportions of differential expressed / up-regulated / down-regulated transcription factors and transcription factor encoding genes in the whole genome. P-value ranges are denoted with single (corrected P-value < 0.1) or triple (corrected P-value < 0.05) asterisks
