Characterization and phylogenetic analysis of the complete mitochondrial genome in Xiaoxiang chicken (Gallus gallus domesticus).

ABSTRACT: Xiaoxiang chicken (Gallus gallus domesticus) is one of the native breeds in the Southeastern of Guizhou province, China. The complete mitochondrial genome sequence of Xiaoxiang chicken (small-sized breed chicken) was obtained for the first time. The mitogenome is 16,784 bp in length, and it contained a D-loop region, two rRNA genes, 13 protein-coding genes, and 22 tRNA genes. A neighbour-joining phylogenetic tree was structured based on the D-loop, which indicated that the Red junglefowl was the direct ancestor of Xiaoxiang chicken, and both were closed to the Silky chicken and Dongan black chicken.

Complete mitochondrial genome and phylogenetic analysis of Huangshan Black chicken (Gallus gallus).

Project description:In this study, we sequenced the complete mitochondrial genome (mitogenome) of the Huangshan Black chicken (HBC). Results showed that the complete HBC mitogenome was 16,785 bp in size, comprising 22 transfer RNA genes, 2 ribosomal RNA genes, 13 protein-coding genes, and 1 non-coding control region (D-loop). The overall nucleotide composition was 32.5% for C, 30.3% for A, 23.7% for T, and 13.5% for G. Phylogenetic analysis showed that the HBC mitogenome was clustered with Xianju chicken, which belonged to the haplogroup D2. Our results therefore demonstrate that the origin of HBC corresponds to haplogroup D2 distribution and might have at least one maternal lineage originated from Southeast Asia.

Characteristics of the complete mitochondrial genome of Douhua chicken (Gallus gallus) and phylogenetic considerations.

Project description:Douhua chicken is a unique local breed from Anhui Province, China. This study aimed to illustrate the Douhua chicken mitogenome and clarify its phylogenetic status by sequencing and annotating the complete mitochondrial genome using high-throughput sequencing and primer walking. Phylogenetic analysis through the Kimura 2-parameter model indicated the maternal origin of Douhua chicken. The results revealed that the mitochondrial genome is a closed circular molecule (16,785 bp) that consists of 13 protein-coding genes, 22 transfer RNA (tRNA) coding genes, two ribosomal RNA (rRNA) coding genes, and a control region. The base composition of the Douhua chicken mitogenome contains 30.3% A, 23.7% T, 32.5% C, and 13.5% G, and the haplotype and nucleotide diversity values are 0.829 (Hd) and 0.00441 (Pi), respectively. Furthermore, 10 haplotypes of D-loop sequences among 60 Douhua chickens were identified and distributed into four haplogroups (A, C, D, and E). Overall, the result of the present study indicates that Douhua chicken may have originated from Gallus gallus, and this process was influenced by Gallus gallus spadiceus, Gallus gallus murghi, and Gallus gallus bankiva. This study provides novel mitogenome data to support further phylogenetic and taxonomic studies on Douhua chicken. Additionally, the findings of this study will provide deeper insights for identifying the genetic relationships among populations and tracing maternal origins based on phylogenetic considerations for use in studies on the geographic conservation, utilization, and molecular genetics of poultry species.

Complete mitochondrial genome of the Thai Red Junglefowl (Gallus gallus) and phylogenetic analysis.

Project description:In this study, we sequenced the complete mitochondrial genome (mitogenome) of the Thai Red Junglefowl (RJF; Gallus gallus) using the next-generation sequencing (NGS) platform of the Ion Torrent PGM. Samples were taken from Mae Wang District, Chiang Mai Province, northern Thailand. Our data showed the complete mitogenome to be 16 785 bp in length, composed by 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and one control region. The genome nucleotide composition was 30.3% A, 23.7% T, 32.5% C, and 13.5% G, resulting in a high percentage of A+T (50.4%). Phylogenetic analysis revealed that the mitogenome belonged to haplogroup X, whereas those of all domestic chickens belong to haplogroups A to G. This newly released mitogenome sequence will advance further evolutionary and population genetics study of the RJF and domestic chicken. The availability of the G. gallus mitogenome will also contribute to further conservation genetics research of a unique species, listed as 'data deficient' in Thailand.

Phylogenetic Studies on Red Junglefowl (Gallus gallus) and Native Chicken (Gallus gallus domesticus) in Samar Island, Philippines using the Mitochondrial DNA D-Loop Region.

Project description:A study was conducted to provide genetic information on the matrilineal phylogeny and genetic diversity of Red junglefowl (RJF) and native chickens in Samar Island, Philippines and to identify the genetic distance between Philippine junglefowls and other RJF species in Southeast Asia using complete mitochondrial DNA D-loop sequences. A total of 5 RJFs and 43 native chickens from Samar Island were included in this study. The results showed that Samar RJFs had a nucleotide diversity of 0.0050±0.0016, which was lower than those of three subspecies of Gallus gallus: G. g. gallus, G. g. spadiceus, and G. g. jabouillei. Meanwhile, Samar native chickens showed lower nucleotide diversity (0.0056±0.0004) than domestic fowls in some neighboring Southeast Asian countries, but higher than those in African and European countries. Phylogenetic analysis showed that 3 haplotypes of Samar RJFs clustered to haplogroup D1, and that 2 haplotypes clustered to haplogroup D2. Chickens native to Samar Island showed 100% resemblance to those in the haplogroup shared by domestic chickens and RJFs. Haplogroups A and B and sub-haplogroups D1 and E1 were the more widely distributed matrilineal lineages in Samar Island. Phylogenetic analysis of Samar RJFs showed that they were closely related to Myanmar RJFs (99.6%), Indonesia RJFs (99.5%), and Thailand RJFs (99.1%). This study is an initial investigation estimating the matrilineal phylogeny and genetic diversity of chicken populations in Samar Island, Philippines for developing strategies aimed at the future conservation and improvement of valuable genetic resources.
