Abstract
The complete mitochondrial genome sequence of the Cenxi classical three-buff chicken was measured by PCR-based methods and analyzed in detail. Our research findings reveal that the entire mitochondrial genome of the Cenxi classical three-buff chicken is a circular molecule consisting of 16,786 bp (GenBank accession number: KM433666). The contents of A, T, C, and G in the mitochondrial genome were found to be 30.27%, 23.75%, 32.49% and 13.49%, respectively. The complete mitochondrial genome of the Cenxi classical three-buff chicken contains a typical structure, including 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and 1 control region (D-loop region). This complete mitochondrial genome sequence provides essential information in understanding phylogenetic relationships among Gallus gallus domesticus mitochondrial genomes.
