Planktotalea frisia SH6-1^T artificial circular chromosome map. Genome comparison of P.frisia SH6-1^T with 6 genome sequenced members of the Pelagic Roseobacter Cluster [9]. Circles (from outside to inside): 1 and 2: Genes encoded by the leading and lagging strand of P.frisia SH6-1^T marked in COG colors in the artificial chromosome map; 3–7: The presence of orthologous genes is indicated for the genomes of Rhodobacterales bacterium HTCC2083, Planktomarina temperata RCA23^T, Rhodobacteraceae bacterium HIMB11, CHAB-I-5 SB2 and Rhodobacteraceae bacterium HTCC2255. The similarity of orthologous genes is illustrated in red to light yellow and singletons in grey (grey: >e^− 10-1; light yellow: <e^− 50- > e^− 10; gold: <e^− 50- > e^− 90; light orange: <e^− 90- > e^− 100; orange: <e^− 100- > e^− 120; red: <e^− 120-0). The two innermost circles represent the GC-content and the GC-skew
