Figure 2. Mitochondrial genomes of four species of Columbicola lice: (A) C. passerinae 2, (B) C. passerinae 1, (C) C. columbae, and (D) C. macourae.
Protein-coding and rRNA genes are indicated in gray, with arrows indicating 5′to 3′directionality in protein-coding genes. Annotated tRNAs are indicated with white triangles on the diagrams and are labeled with IUPAC amino acid letter abbreviations. Control regions are indicated with black segments. Partially assembled chromosomes have white space at the unassembled ends. Black lines indicate intergenic regions.
