Characterization of the first mitochondrial genome of a little Corella (Cacatua sanguinea) and its phylogenetic implications

This study was designed to sequence the first complete mitochondrial genome from a little corella (Cacatua sanguinea). The mitogenome sequence was circular and 16,695 bp in length. In comparison to other available mitogenome sequences belongs to Psittacidae species, this mitogenome encoded a conserved structure consisting of 13 protein-coding genes (PCGs), two rRNA genes, 22 tRNA genes. The lengths of 12S and 16S ribosomal RNA were 975 bp and 1582 bp, respectively. The overall base composition of the mitogenome of C. sanguinea was dominated by higher AT (53.0%) than GC (47.0%) content. The complete mitogenome sequence determined in this study is useful for understanding the more profound evolutionary history and the conservation of C. sanguinea
