The mitochondrial genome (mtGenome) has been little studied in the turkey (Meleagris gallopavo), a species for which there is no publicly available mtGenome sequence. Here, we used PCR-based methods with 19 pairs of primers designed from the chicken and other species to develop a complete turkey mtGenome sequence. The entire sequence (16,717 bp) of the turkey mtGenome was obtained, and it exhibited 85% similarity to the chicken mtGenome sequence. Thirteen genes and 24 RNAs (22 tRNAs and 2 rRNAs) were annotated. An mtGenome-based phylogenetic analysis indicated that the turkey is most closely related to the chicken, Gallus gallus, and quail, Corturnix japonica. Given the importance of the mtGenome, the present work adds to the growing genomic resources needed to define the genetic mechanisms that underlie some economically significant traits in the turkey.
