FIG. 1.

Quantiles of intergenic length for nine completely sequenced Rickettsiales and E. coli. Quantile 75 is the value that 75% of the intergenic lengths fall below. The median is quantile 50. Rickettsiales tend to exhibit longer intergenic sequences than typical bacteria (represented here by E. coli), but this effect is more pronounced in E. ruminantium. Abbreviations: Escol, E. coli; wMel, W. pipientis strain wMel; Anmar, A. marginale; Ricon, R. conorii; Ripro, R. prowazekii; wBm, Wolbachia sp. (subsp. B. malayi strain TRS); Erga, E. ruminantium strain Gardel; Erwe, E. ruminantium strain Erwe; Erwo, E. ruminantium strain Erwo.
