Juxtapositioning of CRholarctica segments in the F. tularensis subsp. tularensis SCHU S4 genome sequence. Shown are the CRholarctica segments from CR1 and CR16, CR4 and CR10, and CR13 and CR15 in their relative organizations in the SCHU S4 genome sequence and the LVS genome sequence. (A) CR1-CR16; (B) CR4-CR10; (C) CR13-CR15. Corresponding genes from the SCHU S4 and LVS genome sequence are indicated by the same color with the locus tag identifier number listed below the genes. The relative positioning and organization of corresponding genes between the two genomes is highlighted by the peach coloring, with inversions reflected by the hourglass shape of the coloring. (C) Putative orthologues of glpK (glycerol kinase), glpF (glycerol uptake facilitator), and glpA (glycerol-3-phosphate dehydrogenase) are indicated above or below the corresponding gene.
