Complete mitogenome sequencing of Andaman buffalo: an endangered germplasm of Andaman and Nicobar Islands, India

Andaman buffalo is an indigenous buffalo of Andaman and Nicobar Islands, India. Over the last decade, it has witnessed a rapid decline in population, necessitating its immediate characterization and conservation. The present study reports the complete mitogenome profile of Andaman buffalo which is 16,359 bp in length and comprised of 37 genes, including 13 protein-coding genes (PCGs), 22 transfer RNAs and two ribosomal RNAs. In addition, one A+T\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\hbox {A}\,+\,\hbox {T}$$\end{document} rich region (D-loop) was also present. A biasness towards A and T base was observed in all the genes. All the PCGs except ND6 were present on heavy strand. Start codons for all the 13 PCGs were ATN codon and abbreviated/truncated stop codons were observed in ND1, ND2, COX3, ND3 and ND4. The phylogenetic analysis revealed that the Andaman buffalo is closely related to buffalo from India and China. The results from this study will help in sketching the conservation plan of the threatened breed.
