Figure 1

Circular representation of the microarray results for the chromosome. The innermost circle shows the genomic islands (BgGI 1-16) in magenta and prophages in yellow. The black lines within this circle indicate the genome position, with 100 kb between each line. Each other circle shows the CGH results for one strain, with the color corresponding to the hybridization signal relative to as4aup (red for lower and blue for higher signal according to the scale bar below the circles). Microarray probes are ordered according to the genomic position in B. grahamii as4aup. The reason why the badA region appears white is that these genes are very long, and therefore the density of probes is lower. The strains are, from inside: 1, mm3up; 2, as4bup; 3, af9up; 4, af30up; 5, af43up; 6, af47up; 7, af66up; 8, af50up; 9, af68up; 10, af156up; 11, cg60up; 12, cg64up; 13, cg90up; 14, af115up; 15, cg147up; 16, as134up; 17, cg120up; 18, af140up; 19, af144up; 20, af163up; 21, af164up; 22, af165up; 23, as224up; 24, as211up; 25, af233up; 26, af206up. Strains 1-15 are of ST1.
