Figure 2. Plot of species-specific GC and AT skew at 4-fold sites at mitochondrial protein-coding genes.

Figure 2

ND3, ND4L, ATP8 and ATP6 were not included in the analysis (see Material and Methods). Empty circles highlight genes with inverted AT and GC skews, all of them belonging to one of the following mitogenomes: Albula glossodonta (Albuliformes: Albulidae, NCBI code NC_005800, AT and GC skews inversion in 9 of 9 genes), Bathygadus antrodes (Gadiformes: Macrouridae, NCBI code NC_008222, AT and GC skews inversion in 4 of 9 genes), Tetrabrachium ocellatum (Lophiiformes: Tetrabrachiidae, NCBI code NC_013879, AT and GC skews inversion in 9 of 9 genes), two Johnius species (Perciformes: Sciaenidae, J. grypotus and J. belangerii, NCBI codes NC_021130 and NC_022464, AT and GC skews inversion in 8 and 9 of 9 genes, respectively).
