Mitochondrial PCGs Provide Novel Insights into Subspecies Classification, Codon Usage and Selection of <i>Cervus canadensis</i> Distributed in Qinghai and Gansu, China.

ABSTRACT: Although Cervus elaphus (Linnaeus, 1758) has been well studied, the subspecific taxonomy of Cervus canadensis populations in Qinghai and Gansu, China, is still controversial, and the mitochondrial characteristics of Cervus elaphus (Linnaeus, 1758) remain incompletely understood. We assembled 89 mitogenomes of C. canadensis from five geographical populations across Qinghai and Gansu. Phylogenetic analysis confirmed that the 89 individuals are taxonomically classified as C. c. kansuensis. Nucleotide compositions showed a higher abundance of adenine and cytosine compared to guanine and thymine in both complete mitogenomes and mitochondrial PCGs. Codon usage analysis revealed a strong preference towards A-ending codons (68.04% of over-represented codons, RSCU
