Genome Island (GI) prediction comparative analyses of
genomes. The C3-41 chromosome was used as reference. From the inside: circle 1, genome scale;circles 2 and 3, GC content and GC skew; circles 4–9, genome of C3-41 (red), 2297 (blue) , LP1-G (green), SSII-1 (sky blue), NRS1693 (yellow) and B14905 (emerald green), with colors from dark to light reflecting the similarity from high to low; circle 10, representative genomes for other Bacillus strains (i.e. B. anthracis strain Ames, B. cereus strain AH187, B. thuringiensis strain BMB171, and B. subtilis strain 168) used as outgroups and displaying similar mapping. The predicted GIs, prophages and toxic genes are marked on the outside of the circles.
