FIG 2 .

Open reading frame (ORF) maps of regions 1 to 5. Regions are oriented so that the majority of the tra genes (red) read left to right. The letter above the red genes indicates the particular tra gene. An open reading frame map, excluding variable IS and RE, is shown for each region, with the locations of IS and RE indicated. Genes encoding selective orthologous proteins present in each region are color coded as indicated above. Genes comprising the type VI secretion system (T6SS) of region 2 are shown (blue). The 24,866-bp region 1 (boxed) and the 17,607-bp region 3 (boxed) are extended to show the likely extent of the MGEs that were transferred between strains.
