Mitochondrial dysfunction motif (MDM) enrichment in stress treatment-specific gene sets and conservation of potential mitochondrial dysfunction stimulon (MDS) genes in Arabidopsis (At), rice (Os) and barley (Hv). (a) Enrichment analysis of the MDM in the upstream promotor region of specific subsets containing all differentially expressed genes (DEGs; |log2 (fold change)| > 1, FDR < 0.05) for each stress treatment in At, Os and Hv; 3AT = 3-amino-1,2,4-triazole, AA = antimycin A, ABA = abscisic acid, MV = methyl viologen, SA = salicylic acid, UV = ultraviolet radiation. The presence of the stringent MDM in all expressed genes in each species and each stress was analysed for significance (p-values; chi-square test, significance (p <0.05) is indicated in red font). (b) Heatmap showing gene expression levels for DEGs of MDS candidate genes in At, Os and Hv. All genes contained the MDM in the 2 kb promotor region and showed differential expression in response to AA and/or 3AT and at least 3 out of 6 stresses. The number of each orthogroup (OG) is indicated and known MDS genes are highlighted with an asterisk. Gene names/annotations refer to the genes in Arabidopsis
