Abstract

This study was aimed to sequence the first complete mitochondrial genome from an Indian ringneck parrot (Psittacula krameri). The mitogenome sequence was circular and 16,413 bp in length. In comparison to other available mitogenome sequences belonging to Psittacidae species, this mitogenome encoded a conserved structure consisting of 13 protein-coding genes (PCGs), two rRNA genes, 21 tRNA genes and a control region; however, this mitogenome missing a tRNA-Glu. The lengths of 12S and 16S ribosomal RNA were 975 bp and 1582 bp, respectively. The overall base composition of the mitogenome of P. krameri was dominated by higher AT (53.5%) than GC (46.5%) content. The complete mitogenome sequence determined in this study would be useful to track the more profound evolutionary history and the conservation of P. krameri.

Highlights

This study was aimed to sequence the first complete mitochondrial genome from an Indian ringneck parrot (Psittacula krameri)
The lung tissue sourced from a deceased juvenile Indian ringneck (P. krameri) in a captive aviary flock in Victoria was used in this study
The sample was stored in appropriate conditions by the Veterinary Diagnostic Laboratory (VDL), Charles Sturt University under the accession number CS16-4047

Summary

Introduction

This study was aimed to sequence the first complete mitochondrial genome from an Indian ringneck parrot (Psittacula krameri). KEYWORDS Avian mtDNA; mitogenome phylogeny; family Psittacidae; Psittacula krameri To evaluate the process of diversity and evolutionary relationships among the majority of Psittacula species including Indian ringneck, a molecular phylogeny was constructed using partial mitochondrial DNA sequence of cytochrome b gene, and demonstrated that the Indian ringneck is the most recent common ancestor of the echo parakeet on Mauritius (Groombridge et al 2004).
