English: The outermost circle (circle 1) represents the scale in Mbp. Circle 2 represents the functional category of the CDSs: green, cell envelope and related processes; blue, intermediary metabolism; yellow, information pathways; orange, other functions; dark purple, proteins of unknown function that are similar to other proteins; light purple, proteins of unknown function without similarity to other proteins. Circles 3 and 4 represent CDSs (excluding transposases) on positive (red) and negative (blue) strands. Circle 5 represents the insertion sequences (in green). Circle 6 represents rRNA (grey) and tRNA (red) genes. Circle 7 represents the pseudogenes (excluding transposase pseudogenes). Circles 8, 9 and 10 represent CDSs (in blue) orthologs (predicted as defined in section “Genome analysis and annotation”) with genes from three environmental Arthrobacter strains: A. chlorophenolicus A6 (circle 8), Arthrobacter sp. FB24 (circle 9) and A. aurescens TC1 (circle 10). Circle 11 represents genes involved in siderophore biosynthesis and export (blue) and in Fe3+/siderophore complexes import (red). Circle 12 and 13 represent the G+C content and GC skew (G−C)/(G+C), respectively, each plotted using a 10-kb window.
