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.

Dear Editor, Instances of food mislabeling and adulteration scandals fo- cus public attention on food safety and market fraud. Such scandals force the authorities to enforce stringent regula- tions on food adulteration. The Chinese government and consumers are paying more attention to food resource qual- ity and safety regulation than ever before. The growing food market requires food authenticity at all stages of product processing, while species identification of raw materials is fundamental for food safety. species substitution causes economical loss to consumers and may negatively affect public sanitation because of possible presence of toxic and parasite-infected species （Galimberti et al., 2013）.
