(A) B. longum strain DJO10A (B) NCC2705. Circle (a) indicates the coding regions by strand. The color of each gene refers to the COG functional categories. Circle (b) lists the number of base pairs (bp). Circle (c) contains the unique genes organized according to the coding strand (first two blocks) with the third block indicating the larger unique regions as defined in the text (blue), a prophage region (red), and rRNA operons (green). Circle (d) illustrates the G+C content. Circle (e) shows tRNA genes with block arrows indicating their coding strand. Circle (f) indicates insertion sequences (IS).
