Complete mitochondrial genome and the phylogenetic position of the zebra shark (Stegostoma fasciatum).

ABSTRACT: The complete mitochondrial genome of the zebra shark (Stegostoma fasciatum) was first determined in this study. The total length of this circle DNA was 16 658 bp, consisted of 37 genes with typical gene order in vertebrate mitogenome. Its nucleotide content was 34.1% A, 25.9% C, 12.5% G and 27.5% T. This mitogenome had 23 bp short intergenic spaces located in 10 gene junctions and 54 bp overlaps located in 11 gene junctions. In the protein-coding genes, two start codons (GTG and ATG) and two stop codons (TAG and TAA/T) were found. The 22 tRNA genes ranged from 66 bp (tRNA-Cys) to 75 bp (tRNA-Leu1). The phylogenetic result showed that S. fasciatum was clustered with the whale shark Rhincodon typus.

Complete mitochondrial genome and phylogenetic position of Chaenodraco wilsoni.

Project description:Chaenodraco wilsoni, a species of Channichthyidae, inhabits in southern ocean. The total length of complete mitochondrial genome of C. wilsoni is 17,432?bp, which encoded 37 genes. Similar to most Antarctic fishes, the ND6/tRNA (glu) translocation and an additional non-coding region linked with ND6 have also occurred in C. wilsoni. The ML tree supports that C. wilsoni has closer relationship with Chionodraco species. Our research will provide more molecular biology information about C. wilsoni and deepen the understanding of Antarctic fishes.

The complete mitochondrial genome of Aquila nipalensis and its phylogenetic position.

Project description:Mitochondrial genome sequences are valuable resources for systematics and conservation biology studies. In this paper, we present the complete mitogenome of Aquila nipalensis which was 18,450?bp in length. The gene content and arrangement were typical for avian mtDNA. The overall A?+?T content of was 54.1%, and the AT skew was calculated as 0.12 for the complete mitogenome of A. nipalensis. The maximum-likelihood (ML) tree based on the concatenated 12 protein-coding genes (PCGs) revealed the basal phylogenetic position of A. nipalensis in Aquila.

The complete mitochondrial genome sequence and phylogenetic position of Gobio coriparoides.

Project description:In this paper, we determined the complete mitochondrial DNA (mtDNA) sequence of Gobio coriparoides and analyzed its phylogenetic position. The complete mitogenome is 16,604 bp in length. It consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and 1 control region. Among the 37 genes, 28 were encoded on the heavy strand, while 9 were encoded on the light strand. The overall base composition was 28.97% for A, 18.06% for G, 26.54% for T, and 26.43% for C, with a higher A + T content (55.51%). There are some overlaps existing in G. coriparoides mitochondrial genome. The neighbor-joining (NJ) phylogenetic tree based on whole mitogenome sequences supported that G. coriparoides is the closest to G. cynocephalus. This result will provide a basic reference for understanding the genetic structure, molecular evolution, and phylogeny of G. coriparoides and related species.

Complete mitochondrial genome and phylogenetic analysis of the copper shark Carcharhinus brachyurus (Gunther, 1870).

Project description:Copper shark (Carcharhinus brachyurus Günther, 1870) is one of the most widely distributed but least known species in the family Carcharhinidae. Herein, we report the first complete mitogenome of C. brachyurus. The overall structure of the 16,704 bp C. brachyurus mitogenome was similar to that of other Carcharhinus species and showed the highest average nucleotide identity (97.1%) with the spinner shark (Carcharhinus brevipinna). Multigene phylogeny using 13 protein-coding genes (PCGs) in the mitogenome resolved C. brachyurus clustered with other species within the genus; the overall tree topology was congruent with recent phylogenetic studies of this species. These results provide important information for conservation genetics and further evolutionary studies of sharks.
