Figure 1.

Circular representation of the chromosome of strain GPE PC73 of X. albilineans. The scale is shown in kbp in the center and around the periphery. Boxes: Albicidin biosynthesis gene cluster (yellow), other large NRPS loci (orange), T3SS SPI-1 gene cluster (red) and flagellum gene cluster (blue). Arrows: 12 copies of the 5-kb gene cluster present at 12 different locations of the chromosome (purple), locus CRISPR-1 (green), locus CRISPR-2 (sky blue) and short NRPS loci containing only a short NRPS gene (orange). The grey circle shows the GC skew (G-C)/(G+C) using a 100-base window. The black circle shows the G+C content using a 100-base window
