Determination and phylogenetic analysis of the complete mitochondrial genome of Bubalus bubalis Linnaeus, 1758 breed Murrah (Artiodactyla: Bovidae)

Abstract

Murrah buffalo (Bubalus bubalis Linnaeus, 1758 breed Murrah, MB) is a most productive water buffalo breed. It is the first time that the complete mitochondrial genome sequence of the MB was reported. The total length of the mtDNA is 16,359 bp, It contains the typical structure, including 22 transfer RNA genes, 2 ribosomal RNA genes, 13 protein-coding genes and 1 non-coding control region (D-loop region). The overall composition of the mtDNA was estimated to be 33.00% for A, 26.32% for T, 26.71% for C and 13.97% for G. Phylogenetic analyses using N-J computational algorithms showed that the analyzed 18 Ruminantia species are divided into four major clades: Bovidae, Cervidae, Giraffidae and Atilocapridae. In addition, our work confirmed that MB and Bubalus bubalis isolate India 4 have a close genetic relationship.
