The first complete mitogenome of Indian ringneck (Psittacula krameri) demonstrates close phylogenetic relationship with Eclectus parrot

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.
