Variability of genes associated with plasmids and transposons in 16 Aeromonas strains and species. Red indicates genes with higher signal intensity for the tester than the control strain (higher copy number than in strain A449). Green indicates genes with lower signal intensity for the tester than the control (divergent in sequence or missing or at lower copy number). Gene order reflects results of hierarchical clustering of genes performed as described in Materials and Methods. The strains are ordered as in Figure 1, and unless otherwise noted, all other isolates are A. salmonicida subsp. salmonicida. ^aAsm – A. salmonicida subsp. masoucida, ^bAsa – A. salmonicida subsp. achromogenes, ^cAss – A. salmonicida subsp. salmonicida. (A) All genes from the plasmid functional category. The blue bars (both light and dark) indicate genes found on plasmid 5, and the dark blue bars correspond to predicted TTSS genes. (B) All genes from the transposon functional category. The orange bars indicate genes with strong sequence similarity to known transposases.
