Fig. 7: Comparative transcriptomics analysis.

a Heat map of the 447 identified genes. Red font indicate upregulated expression genes and blue font indicate downregulated expression genes in ΔiolR mutant, respectively. b Gene Ontology (GO) classification of differentially expressed genes. The differentially expressed genes are grouped into three hierarchically structured terms: biological process, cellular component and molecular function. c Relative mRNA expression levels of 20 differentially expression genes in ΔiolR mutant and wild-type strains. The results were normalized to those of RecA and then were expressed as n-fold increases with respect to the control. Error bars represent the standard deviations from at least three independent experiments.
