Fig. 1. Organizational maps of the 13 new mitogenomes sequenced in this study. Genes labelled above the line are transcribed in the same direction from left to right, while genes labelled below the line are transcribed in the same direction from right to left. The genes and intergenic spacers are scaled to their length in the mitogenome.
