The chromosome and six plasmids of Rlv3841. The plasmids are shown at the same relative scale, and the chromosome at one-fourth of that scale. Circles from outermost to innermost indicate genes in forward and reverse orientation: all genes, membrane proteins (bright green), conserved and unconserved hypotheticals (brown conserved, pale green unconserved), phage and transposons (pink, shown for pRL7 only), and (for the chromosome only) DNA transcription/restriction/helicases (red) and transcriptional regulators (blue). Inner circles indicate deviations in G+C content (black) and G-C skew (olive/maroon). The full list of Sanger Institute standard colors for functional categories is as follows: white = pathogenicity/adaptation/chaperones (shown here in black); dark grey = energy metabolism (glycolysis, electron transport, among others); red = information transfer (transcription/translation + DNA/RNA modification); bright green = surface (inner membrane, outer membrane, secreted, surface structures [lipopolysaccharide, among others]); and dark blue = stable RNA; turquoise = degradation of large molecules; pink/purple = degradation of small molecules; yellow = central/intermediary/miscellaneous metabolism; pale green = unknown; pale blue = regulators; orange/brown = conserved hypo; dark brown = pseudogenes and partial genes (remnants); light pink = phage/insertion sequence elements; light grey = some miscellaneous information (for example, Prosite) but no function. bp, base pairs; Rlv3841, R. leguminosarum biovar viciae strain 3841.
