Complete mitochondrial genome of the porbeagle shark, Lamna nasus (Chondrichthyes, Lamnidae).

ABSTRACT: We report for the first time, the complete mitochondrial genome sequence of the porbeagle shark, Lamna nasus, from a specimen collected from offshore waters of New England, USA in the western North Atlantic Ocean. The genome structure of this species is similar to the other reported shark mitogenomes. The genome sequence has a total length of 16,697 bases; similar in size to the mtDNA genomes reported for other lamnid species. A Bayesian phylogenetic tree was reconstructed for the Lamnidae family using mitogenome sequences available in the Genbank.

The published complete mitochondrial genome of the milk shark (Rhizoprionodon acutus) is a misidentified Pacific spadenose shark (Scoliodon macrorhynchos) (Chondrichthyes: Carcharhiniformes).

Project description:The recently published mitogenome of milk shark Rhizoprionodon acutus (MN602076/NC_046016) was fully resolved in an unexpected phylogenetic position in the original mitogenome announcement, which rendered the genus Scoliodon paraphyletic. Here, we show that this mitogenome is actually that of a misidentified Pacific spadenose shark (Scoliodon macrorhynchos). The error is documented to avoid the perpetuation of erroneous sequence information in the literature.

Complete mitochondrial genome of the nurse shark Ginglymostoma cirratum.

Project description:We determined the complete mitochondrial genome sequence of nurse shark Ginglymostoma cirratum. The circular DNA of 16692?bp comprises 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs, a non-coding control region and a non-coding origin of light strand replication with typical gene order of vertebrates. The nurse shark formed a well-supported clade that included whale shark Rhincodon typus and zebra shark Stegostoma fasciatum within the Orectolobiformes in a phylogenetic tree constructed with other published mitochondrial genomes of sharks.

Complete mitochondrial genome of the winghead shark, Eusphyra blochii (Elasmobranchii: Sphyrnidae).

Project description:The complete mitochondrial genome (16,726?bp) of the winghead shark, Eusphyra blochii is presented. This species is exploited throughout parts of its range, and is currently listed as Near Threatened by the IUCN Red List. A phylogenetic analysis placed E. blochii within the Carcharhiniformes, as a sister taxon to Sphyrna lewini and S. zygaena.

The complete mitochondrial genome of the endangered great hammerhead shark, Sphyrna mokarran.

Project description:We present the first mitochondrial genome sequence of the great hammerhead shark, Sphyrna mokarran. This species is of considerable conservation concern throughout its global distribution, and currently listed as Endangered on the IUCN Red List. The mitochondrial genome is 16,719?bp in length with 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and a non-coding control region. The gene arrangement is congruent with other shark and most vertebrate species. This S. mokarran mitogenome provides a genomic resource for assisting with population studies and conservation efforts for this highly depleted species.

Complete mitochondrial genome of the gray reef shark, Carcharhinus amblyrhynchos (Carcharhiniformes: Carcharhinidae).

Project description:We report the first mitochondrial genome sequences for the gray reef shark, Carcharhinus amblyrhynchos. Two specimens from the British Indian Ocean Territory were sequenced independently using two different next generation sequencing methods, namely short read sequencing on the Illumina HiSeq and long read sequencing on the Oxford Nanopore Technologies' MinION sequencer. The two sequences are 99.9% identical and are 16,705 base pairs (bp) and 16,706 bp in length. The mitogenome contains 22 tRNA genes, two rRNA genes, 13 protein-coding genes and two non-coding regions; the control region and the origin of light-strand replication (OL).

The complete mitochondrial genome of an Atlantic Ocean Shortfin Mako Shark, Isurus oxyrinchus.

Project description:We report the first complete mitochondrial genome of a shortfin mako shark from the Atlantic Ocean. The genome had 16,700 base pairs and contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a non-coding D-loop. There were 81 individual differences compared to the published mitochondrial genome of a shortfin mako from the Pacific Ocean, with most variability found in protein coding genes, especially ND5, ND3, and ND1. These highly variable genes may be useful population markers in future studies, and availability of a second mitogenome will assist with future, genome-scale studies of this IUCN Endangered species.

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

Project description: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 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.
