(A) Part of complete mitogenome alignment map of Equus; rectangles for PCGs, lozenges for rRNA, circles for tRNA, the arrows are their transcriptional direction. Unshown species are same with our samples. (B) The relative synonymous codon usage (RSCU) in the mitogenome of E. asinus (PP049795). (C) Comparative analysis of selective pressures exerted on PCGs for all Equus. Ka/Ks ratios for all 13 PCGs of all Equus; red for Ka value, bule for Ks value, and yellow line graph refers to Ka/Ks value. The left vertical axis represents the Ka or Ks, while the right vertical axis represents the Ka/Ks ratio.
