Overview of genomes and transcriptomes. A. Circle diagram of the MG1655 and MDS42 genomes. The genes present in MG1655 and MDS42 are shown in the outer and inner rings, respectively, and visualized using Circos [30]. The gold boxes indicate the deleted segments that were originally reported [17]. The point mutations in MG1655 are indicated with red tick marks. The origin and terminus of replication are indicated outside of the circle. B. Box plot of gene expression in MG1655 and MDS42. The average expression levels of 4428 and 3710 genes in MG1655 and MDS42, in exponential phase growth or under heat shock conditions, are shown in pink (MG1655), green (MG1655_heatshock), cyan (MDS42) and purple (MDS42_heatshock), respectively. The expression levels are represented by the log-scale mRNA concentrations. The dots represent the genes.
