Determination and analysis of the complete mitochondrial genome sequence of Taoyuan chicken

Taoyuan chicken is excellent native breeds in China. This study firstly determined the complete mitochondrial genome sequence of Taoyuan chicken using PCR-based amplification and Sanger sequencing. The characteristic of the entire mitochondrial genome was analyzed in detail, with the base composition of 30.26% A, 23.79% T, 32.44% C, 13.50% G in the Taoyuan chicken (16,784 bp in length). It contained 2 ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes and a major non-coding control region (D-loop region). The complete mitochondrial genome sequence of Taoyuan chicken will be useful for the phylogenetics of poultry, and be available as basic data for the genetics and breeding.
