Linear organization of E. zuernii mtDNA. The order and transcriptional direction of three coding regions for cytb, cox1, and cox3 are indicated by purple arrows and fragments of seven SSU (green) and 12 LSU (light blue) rDNAs are detected between the protein-coding regions and identical to those of other congeneric species. The nomenclature of these ribosomal fragments follows the convention of Feagin et al. (2012) [40]. Positive and negative GC-skew and GC content are indicated in dark green, purple, and black, respectively, across the whole genome
