FIG.1.

CGH of 42 Bordetella strains. Each column represents a strain, ordered and color-coded according to the tree topology shown in Fig. 2. The three sequenced strains are marked by asterisks. B. pertussis strain 18323 is indicated by the dagger. Each row represents a microarray probe, arranged in RB50 gene order from “start” to “end,” with RB50 genome coordinates listed on the left. φ indicates clusters of phage genes. Arrowheads indicate regions of >5 kb not represented by a probe. Magenta bar, duplicated sequences in RB50. The chromosomal locations of the largest of these duplications, a degenerate prophage, are marked by magenta arrowheads. Yellow bar, genes not present in the RB50 sequence, arranged in Tohama I gene order. The values below the color bar at the bottom refer to log₂(test/reference intensities). Missing data are gray. Bp, B. pertussis; Bb, B. bronchiseptica; Bpp, B. parapertussis.
