ABSTRACT
The wedge-tailed green pigeon (Treron sphenurus) has a protective value in the evolution of the family Columbidae. In this study, the complete mitogenome of T. sphenurus from Baise City, China, which represents the first sequenced species of the genus Treron in Tribe Treronini, is reported. This was accomplished using PCR-based methods and a primer-walking sequencing strategy with genus-specific primers. The mitogenome was found to be 18,919 bp in length comprising 37 genes, including 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and one control region. In terms of structure and composition, many similarities were found between the T. sphenurus and Hemiphaga novaeseelandiae (New Zealand pigeon) mitogenomes. This was further supported by phylogenetic analysis showing that T. sphenurus has a close evolutionary relationship with H. novaeseelandiae. The complete mitogenome of T. sphenurus reported here is expected to provide valuable molecular information for further studies on the phylogeny of the genus Treron and for analyses of the taxonomic status of the family Columbidae.

To understand the genetic diversity of Peking gecko (Gekko swinhonis) populations in its endemic region, 60 individuals were sampled from Lushan, Qi, and Linying counties in Henan Province, China. Through PCR amplification and Sanger sequencing, 120 sequences with lengths of 652 bp (COI) and 739 bp (Cyt b) were obtained, and nine haplotypes were detected for each gene. Overall, results indicated that Peking gecko populations in China have high genetic diversity and significant genetic differentiation. This study provides necessary scientific basis for the protection of Peking gecko germplasm resources.
ABSTRACT
Here, we report the complete mitochondrial genome of Aratinga nenday. It was found to be a closed circular molecule of 16,983 bp, containing 22 transfer RNA genes, 13 protein-coding genes, 2 ribosomal RNA genes, and 1 non-coding control region. The overall base composition was 54.03% A + T and 45.973% G + C contents. The complete mtDNA of A. nenday and other 14 species were subjected to phylogenetic analysis by the neighbour-joining method and the Kimura 2-parameter model, which showed A. nenday to be a sister to the congeneric Aratinga solstitialis.
ABSTRACT
In this paper, we reported the complete mitogenome of Agapornis lilianae. A. lilianae mitogenome is 16,720bp base pairs long. The overall base compositions of complete mitogenomes of A. lilianae is 29.66% A, 21.5% T, 34.59% C, 14.25% G. All genes exhibit the typical mitochondrial gene arrangement and transcribing directions. The phylogenetic analysis based on 21 mitochondrial sequence data suggested that A. lilianae are closely related to the same genus specie Agapornis roseicollis. The results obtained here would be useful for the conservation and phylogeny of A. lilianae.
ABSTRACT
The complete mitochondrial genome of Agapornis nigrigenis was obtained using Sanger sequencing. The mitochondrial genome from A. nigrigenis is 16,718 bp in length. Its genome with an overall GC content of 48.86%, contained 22 transfer RNA genes, 13 protein-coding genes, 2 ribosomal RNA genes, and 1 control region. The phylogenetic position of A. nigrigenis based on the 18 parrots species showed it was sister to the same genus specie Agapornis roseicollis. The results obtained here can contribute to molecular evolution and phylogeny of parrots further.
ABSTRACT
In this study, we characterized the complete mitochondrial genome of Agapornis personatus. Its mitochondrial genome is a circular molecule of 16,722 bp, with all genes exhibiting typical mitochondrial gene arrangement and transcribing directions. The overall base composition is 21.49% T, 34.6% C, 29.66% A, and 14.25% G. Phylogenetic analysis of the complete mitogenome was conducted using the neighbour-joining method based on 16 parrot species. Phylogenetic tree suggested that A. personatus was closest to the same genus specie Agapornis roseicollis. The results would be useful for further studies on molecular evolution and breeding works of A. personatus.
