Sequencing and characterization of the complete mitochondrial genome of Mishmi takin (Budorcas taxicolor taxicolor) and comparison with the other Caprinae species

Mishmi takin (Budorcas taxicolor taxicolor) is an endangered and least studies species. We sequenced and annotated a 16,584 bp long complete mitogenome of Mishmi takin (B. t. taxicolor). It was encoded by 37 genes: 13 Protein-Coding Genes (PCGs), two ribosomal RNA genes, 22 transfer RNA, and non-coding control region. All tRNA genes show a typical secondary cloverleaf structure, except tRNAser(AGY) in which dihydrouridine arm did not form a stable structure. We observed 82 bp nucleotide deletions in the control region of Mishmi takin. The overall analysis of 13 PCGs, two rRNA and 22 tRNA of Mishmi takin indicates its close relationship with the B. t. tibetana than the B. t. bedfordi. The overall genetic similarity indicated that all takin species is closely related to the P. nayaur than the C. ibex and Ovibos moschatus. This study provides a useful resource for further studies on conservation and population genetics of Budorcas.
