The various genomic parameters relevant to the base composition skews of the bacterial chromosomes. The bacteria are arranged in Genus (top) and Groups (1–19, Figure 1; shaded), and numbered [see Additional file 1 for complete list]. (Top panel) G+C contents and χCDS. (Middle panel) χG cd , σG d , σG g , σGR, and σGT. (Bottom panel) χA cd , σA d , σA g , σAR, and σAT. Filled squares are for the leading strands, and open squares are for lagging strands.
