Characterization of the diversity of barn owl's mitochondrial genome reveals high copy number variations in the control region.

ABSTRACT: Mitochondria are known to play an essential role in the cell. These organelles contain their own DNA, which is divided in a coding and non-coding region (NCR). While much of the NCR's function is unknown, tandem repeats have been observed in several vertebrates, with extreme intra-individual, intraspecific and interspecific variation. Taking advantage of a new complete reference for the mitochondrial genome of the Afro-European Barn Owl (Tyto alba), as well as 172 whole genome-resequencing; we (i) describe the reference mitochondrial genome with a special focus on the repeats in the NCR, (ii) quantify the variation in number of copies between individuals, and (iii) explore the possible factors associated with the variation in the number of repetitions. The reference mitochondrial genome re
