title: Complete mitochondrial genome of endangered Yellow-shouldered Amazon (Amazona barbadensis): two control region copies in parrot species of the Amazona genus.
abstract: Amazona barbadensis is an endangered species of parrot living in northern coastal Venezuela and in several Caribbean islands. In this study, we sequenced full mitochondrial genome of the considered species. The total length of the mitogenome was 18,983 bp and contained 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, duplicated control region, and degenerate copies of ND6 and tRNA (Glu) genes. High degree of identity between two copies of control region suggests their coincident evolution and functionality. Comparative analysis of both the control region sequences from four Amazona species revealed their 89.1% identity over a region of 1300 bp and indicates the presence of distinctive parts of two control region copies.
