Dataset Information

Complete mitochondrial genomes reveal the phylogenetic relationships of Duoma with eight representative sheep breeds and two ovis species.

ABSTRACT: The Ovis aries Duoma breed is one of the most important alpine grassland-type sheep breeds in China. In this current study, we first reported the complete mitochondrial genome of Duoma sheep. Mitochondrial genome is 16,618 bp in length and exhibits the same typical structure as the other published sheep breeds. The genome contains 37 genes (22 tRNA, two rRNA, and 13 protein-coding genes (PCGs)) and a control region (D-loop region). Phylogenetic analysis shows that the Duoma sheep breed is closer to Ganjia sheep. Our findings will help the further evolution and conservation studies of Duoma sheep.

Project description:Anemonefishes (Pomacentridae Amphiprioninae) are a group of 30 valid coral reef fish species with their phylogenetic relationships still under debate. The eight available mitogenomes of anemonefishes were used to reconstruct the molecular phylogenetic tree; six were obtained from this study (Amphiprion clarkii, A. frenatus, A. percula, A. perideraion, A. polymnus and Premnas biaculeatus) and two from GenBank (A. bicinctus and A. ocellaris). The seven Amphiprion species represent all four subgenera and P. biaculeatus is the only species from Premnas. The eight mitogenomes of anemonefishes encoded 13 protein-coding genes, two rRNA genes, 22 tRNA genes and two main non-coding regions, with the gene arrangement and translation direction basically identical to other typical vertebrate mitogenomes. Among the 13 protein-coding genes, A. ocellaris (AP006017) and A. percula (KJ174497) had the same length in ND5 with 1,866 bp, which were three nucleotides less than the other six anemonefishes. Both structures of ND5, however, could translate to amino acid successfully. Only four mitogenomes had the tandem repeats in D-loop; the tandem repeats were located in downstream after Conserved Sequence Block rather than the upstream and repeated in a simply way. The phylogenetic utility was tested with Bayesian and Maximum Likelihood methods using all 13 protein-coding genes. The results strongly supported that the subfamily Amphiprioninae was monophyletic and P. biaculeatus should be assigned to the genus Amphiprion. Premnas biaculeatus with the percula complex were revealed to be the ancient anemonefish species. The tree forms of ND1, COIII, ND4, Cytb, Cytb+12S rRNA, Cytb+COI and Cytb+COI+12S rRNA were similar to that 13 protein-coding genes, therefore, we suggested that the suitable single mitochondrial gene for phylogenetic analysis of anemonefishes maybe Cytb. Additional mitogenomes of anemonefishes with a combination of nuclear markers will be useful to substantiate these conclusions in future studies.
