English: Schematic representation of the genome of Archaeoglobus neptunius SE56^T. Labeling from the outside to the center is as follows:
circle 1, genes on the forward strand;
circle 2, genes on reverse strand [tRNAs yellow, ribosomal RNAs (rRNAs) lilac pink, and clustered regularly interspaced short palindromic repeats (CRISPR) cyan blue];
circle 3, G + C skew;
circle 4, G + C content;
circle 5, genomic islands shown as red, blue, and orange rectangles attributed, respectively, to integrated, IslandPath-DIMOB and SIGI-HMM prediction genomic islands methods; and
circle 6, IslandViewer4 automatic calculation of the G + C content.
