The complete mitochondrial genome of Ovis ammon darwini (Artiodactyla: Bovidae)

摘要

Ovis ammon darwini: has been listed as a nearthreatened species by IUCN-World Conservation Union due to over-hunting and poaching, competition with domestic livestock, and habitat destruction. Study on molecular biology research provides the scientific basis for the protection and sustainable utilization of key endangered species. Mitochondrial genome is very useful for researches in ecology, systematics and conservation biology. In this study, the complete mitochondrial genome sequence of O. a. darwini was determined by next-generation sequencing data, which is 16,618 bp in length and contains 13 proteincoding genes(PCGs), 2 rRNAs genes, 22 tRNAs genes and a non-coding control region. Base composition of genome is A(33.7 %), C(25.8 %), G(13.1 %), T(27.4 %) with an A + T content of 61.1 %. Phylogenetic analysis suggested that the systematic status of O. a. darwini was more closed related to O. a. hodgsoni clustered with O. ammon. The mitogenome of O. a. darwini offered significant information for molecular genetic research of O. ammon.
