摘　　要： DEAR EDITOR, In this study, we sequenced the complete mitochondrial DNA genome （mitogenome） of the Zhengyang Yellow chicken （Gallus gallus domesticus） by next-generation sequencing technology. Samples were taken from Zhumadian city, Henan Province, China. The complete mitogenome was 16 785 bp in size, and had a nucleotide composition of 30.3% （A）, 23.7% （T） 32.5% （C）, and 13.5% （G）, with a high AT content of 54.0%. The assembled mitogenome exhibited typical mitochondrial DNA （mtDNA） structure, including a non-coding control region, two rRNA genes, 13 protein-coding genes, and 22 tRNA genes. Phylogenetic analysis indicated that this mitogenome defined a novel sub-haplogroup B3 within haplogroup B. These results should provide essential information for chicken domestication and insiqht into the evolution of genomes.
