Summary 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.
