The complete mitochondrial genome of the Chinese indigenous dog.

In this study, the complete nucleotide sequence of Chinese indigenous dog mitochondrial genome was determined for the first time. Sequence analysis showed that the genome structure was in accordance with other dogs. It contained 22 tRNA genes, 2 ribosomal RNA genes, 13 protein-coding genes and 1 control region (D-loop region). The base composition was A (31.6%), G (14.2%), C (25.5%) and T (28.7%), so the percentage of A and T (60.3%) was higher than that of G and C. The complete mitochondrial genome sequence of the Chinese indigenous dog would shed a new light on further studies in dog domestication.
