Circular maps of the Providencia sneebia genome and plasmids. (A) P. sneebia genome. The contigs are ordered and oriented as they are in the physical genome based on an optical map, including the sizes of the gaps between contigs. Rings from the outermost to the center: 1) genes on the forward strand (blue), 2) genes on the reverse strand (blue), 3) tRNA and rRNA genes (black), 4) genes unique to P. sneebia when comparing all 8 Dmel and HMP Providencia genomes (orange), 5) individual assembly contigs (alternating shades of grey), 6) GC skew. (B) pPSN1. (C) pPSN2. (D) pPSN3. All plasmids have the genes on the forward strand on the outermost ring and genes on the reverse strand on the inner ring.
