Figure 3.

Linearized comparison of the mitochondrial gene arrangement of 13 flatworm species. Gene and genome size are not to scale. All genes are transcribed in the same direction (from left to right). The tRNAs are labeled by single-letter abbreviations and two leucine and two serine tRNA genes are marked, according to their anticodon sequence, as L1 (trnL-uag), L2 (trnL-uaa), S1 (trnS-gcu), and S2 (trnS-uga), respectively. The non-coding regions are denoted by the NR according to the previous authors. An unassigned region, located between the HHR (highly repetitive region) and nad6 in M. sebastis mtDNA is marked by UAR. Homologous genes between the taxa are indicated by connected lines.
