Figure 3. Genome localization ofSalmonella gtr operons.

Figure 3

Circular representation of the serogroup B S. Typhimurium D23580 genome (accession number FN424405) indicating that 9 GtrC families localize to four genomic regions (locus 1–4) relative to the D23580 genome. The italicized locus 3 (SPI-17) site is not represented in KW serogroup B genomes and thus, its relative location in S. Typhimurium D23580 is shown. Triangular gtr operons point the common location of GtrC family members. Pentagonal gtr operons are associated with full-length prophage. Dotted pentagonal operons with the phi symbol ‘Φ’ indicate gtr operons associated with full-length prophage that do not localize with their ‘parent’ GtrC family members. Gtr acronyms for these three gtr operons are shown (Table S1). Color code of the pentagon/triangles relate to the GtrC family clustering defined in Figure 1. The circular S. Typhimurium D23580 genome depicts forward open reading frames in blue, reverse open reading frames in red and tRNA in black.
