Example of the trmE integration hotspot and its different contents in the Salmonella enterica typhimurium (ST), P. luminescens TT01 (Pl), P. asymbiotica ATCC43949 (Pa), X. nematophila ATCC19061 (Xn) and X. bovienii SS-2004 (Xb) genomes. The boxes above and below the axis represent ORFs in the forward and reverse orientations, respectively. The ORF coding for trm E is highlighted in gray at the end of each RGP. The putative functions of ORFs within RGPs are indicated by specific colors (see the legend below the figure). Identical subregions are linked by dotted lines.
