Abstract
In this work, we reported the complete mitochondrial genome sequence of the Ningxiang pig (Human Province), which was determined through PCR-based method. The total length of the mitogenome is 16,690 bp. The overall composition of the mitogenome was estimated to be 34.70% for A, 25.81% for T, 26.18% for C, 13.30% for G, respectively, indicating that an A + T(60.52%)-rich feature occurs in the Ningxiang pig. It contains the typical structure, including 2 ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes and 1 non-coding control region (D-loop region). The arrangement of these genes was the same as that found in the Landrace pig. All the protein initiation codons are ATG, except for ND2. ND3 and ND5 are ATA, ND4L is GTG. The complete mitochondrial genome sequence of the Ningxiang pig in Human Province provides an important data for further study about genetic mechanism.
