Abstract

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.

Highlights

This study was designed to sequence the first complete mitochondrial genome from a little corella (Cacatua sanguinea)
Cockatoos are restricted to the Australasian region, ranging from the Philippines and eastern Indonesian islands of Wallacea to New Guinea, the Solomon Islands and Australia (Cameron and Cunningham 2006)
A swab sample moistened in sterile phosphate-buffered saline, of the choana and cloaca was taken from a freeranging Little Corella (C. sanguinea) originating from Nunawading, Victoria (Sample ID: #46, GPS location: Latitude: 374902.4600S, Longitude: 14510037.200E) and was used in this study

Summary

Introduction

This study was designed to sequence the first complete mitochondrial genome from a little corella (Cacatua sanguinea). KEYWORDS Avian mtDNA; mitogenome phylogeny; order Psittaciformes; Cacatua sanguinea Psittaciformes is a large and diverse avian that order contains over 370 species placed within approximately 74 genera, most of which are distributed in the tropical parts of the Southern Hemisphere (Astuti et al 2006; White et al 2011).
