摘要： Shigaste humped cattle (Bos taurus), generated through long-term breeding, is a distinctive but threatened species native to China. This species plays an essential role in local stockbreeding and breeding newer species. Its population has been declining rapidly over the past few years owing to poor understanding of the significance of conservation of germplasm resources and the introduction of abundant species. To effectively protect and wisely utilise cattle breed resources, researchers have performed extensive studies on genetic diversity of domestic animals. In this study, the complete mitochondrial genome sequence of Shigaste humped cattle was successfully obtained by Illumina Hiseq Xten platform. The circular genome is 16,340 bp, which is composed of 13 protein-coding genes, two rRNA genes, 22 tRNA genes and a control region. Base composition of the genome is A (33.4%), C (26.0%), G (13.4%), T (27.2%), with an A + T content of 60.6%. Phylogenetic relationship based on 10 mitochondrial genome sequences indicated that Shigaste humped cattle was clustered with domestic cattle from China, and was closely related to Bos indicus. This study provided detailed molecular genetic information for the conservation and utilization of cattle germplasm resources.
