Fig. 4.

Conserved responses in gene expression of orthologous genes following treatments in Arabidopsis, rice and barley. Log2-transformed fold-changes are shown as a heatmap for the 20 orthogroups [24] that contained differentially expressed genes (DEGs) showing conserved responses across 4 out of 6 treatments (3AT = 3-amino-1,2,4-triazole, AA = antimycin A, ABA = abscisic acid, MV = methyl viologen, SA = salicylic acid, UV = ultraviolet radiation) for each of the three species (A = Arabidopsis, O = Rice and H = Barley). Genes with known functions (Supplemental Table 7a) (mutants/over-expressors) in development, defence and/or redox homeostasis are indicated in red. Underlining indicates genes encoding transcription factors
