Complete mitochondrial genome sequence of the Przewalski’s gazelle (Procapra przewalskii)

Abstract

Przewalski’s gazelle (Procapra przewalskii) is one of the most endangered species listed in the IUCN Red List. It is endemic to China and a flagship species in the eastern part of the Qinghai-Tibetan Plateau. Here, we assembled the complete mitochondrial genome (mitogenome) of P. przewalskii for the first time. Moreover, we conducted the phylogenetic analysis including other 11 species of subfamily Antilopinae and two species of subfamily Caprinaeas as outgroups. The complete mitogenome of P. przewalskii was 17,376 bp in length, and contained 13 protein-coding genes (PCG), two ribosomal RNA genes (12S rRNA and 16S rRNA), 22 transfer RNA (tRNA) genes and a non-coding control region (D-loop). Among the tRNA genes, both the tRNASer and tRNALeu had a replication. The base content of the mitogenome was that A, C, G and T occupied 33.9, 24.5, 13.3 and 28.3%, respectively. The GC content was 37.8% accordingly. The molecular phylogenetic analysis showed that Przewalski’s gazelle had a close relationship with Mongolian gazelle (P. gutturosa).
