Figure 1

Circular representation of the X. albilineans chromosome (strain GPE PC73). The scale is shown in megabases around the periphery. Moving inward, the first three circles show CDSs conserved in X. fastidiosa strain 9a5c (in red), S. maltophilia strain R551-3 (in green) and X. axonopodis pv. vesicatoria strain 85-10 (in blue), respectively (forward and reverse-strand conserved CDSs are shown in the same circle). In the next circle, the NRPS gene clusters (except the albicidin biosynthesis gene cluster) are shown in pink, the albicidin biosynthesis gene cluster is shown in yellow, the T3SS SPI-1 gene cluster is shown in blue, genes encoding proteins that contain repeated Rhs elements are shown in brown, and a large phage-related sequence is shown in grey. The black circle shows the G+C content using a 100 base window. The brown and orange circle shows the GC skew (G-C)/(G+C) using a 100 base window.
