Gene expression differences between WT and res plants in roots and leaves. (a) Venn diagrams showing the number of differentially expressed genes (DEGs) comparing WT and res in absence of salt stress (control) and exposed to 200 mM NaCl for 5 days (Salt), as well as the overlap of genes commonly expressed in both conditions. Numbers in parentheses are the total number of DEGs in control and salt stress in both tissues. DEGs are those showing a FDR < 0.05 and a minimum fold-change value of 2.0. (b) Four-way Venn diagram showing the relationship between DEGs identified in each tissue and treatment. Leaf-Control and Root-Control represent DEGs in res vs WT in each tissue in absence of salt stress, whereas Leaf-Salt and Root-Salt include DEGs in res vs WT in each tissue during salt stress. (c) Number of DEGs classified in functional categories for each tissue using Mapman, both in control and salt stress
