Severe strand asymmetry of the mitochondrial genome sequence of S. erythranum. A. Scatterplots of skew values calculated for the whole majority strand for 360 arthropods. The value for S. erythranum (-0.351, 0.350) is indicated by the triangle at left, with the other arthropods represented by diamonds. B. Nucleotide composition (center), AT-skew (below) and GC-skew (above) of all 13 PCGs and two ribosome RNA genes of the S. erythranum mitogenome. All values are calculated for the majority strand.
