Complete mitochondrial genome and the phylogenetic position of the snaggletooth shark Hemipristis elongata (Carcharhiniformes: Hemigaleidae).

ABSTRACT: In this study, we first present the complete mitochondrial genome of Hemipristis elongata, the only member of genus Hemipristis in family Hemigaleidae. It is 16,691?bp in length with the typical gene order invertebrates. Its overall base composition is 31.7% A, 24.1% C, 12.9% G and 31.3% T. Two start codons (ATG and GTG) and three stop codons (TAG, AGA and TAA/T) are found in the protein-coding genes. The 22 tRNA genes ranged from 67?bp (tRNA-Cys, tRNA-Ser2) to 75?bp (tRNA-Leu1). The phylogenetic result showed that H. elongata was clustered to Hemigaleus microstoma and formed Hemigaleidae.

Complete mitochondrial genome and the phylogenetic position of the blackspotted catshark Halaelurus burgeri (Carcharhiniformes: Scyliorhinidae).

Project description:In this study, the mitogenome of the blackspotted catshark Halaelurus burgeri was first determined. This circle molecular was rich in A (30.7%)+T (30.4%), poor in C (25.0%)+G (13.8%) and contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a longest control region (3481 bp with lots of repeated motifs) in sharks. Two start codons (ATG and GTG) and two stop codons (TAG and TAA/T) were found in the protein-coding genes. The 22 tRNA genes ranged from 66 bp (tRNA-Ser2) to 75 bp (tRNA-Leu1). The phylogenetic result showed that H. burgeri did not cluster to the two species of Scyliorhinidae (Cephaloscyllium umbratile and Scyliorhinus canicula).

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).

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.

Characterization of the complete mitochondrial genome of the common smoothhound shark, Mustelus mustelus (Carcharhiniformes: Triakidae).

Project description:We present the complete mitochondrial genome of the common smoothhound , Mustelus mustelus,which is 16,755 bp long, contains 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and non-coding control region. All protein-coding genes begin with the ATG codon, except for the COI gene, which begins with GTG. Six protein-coding genes terminated with the TAA codon, and six with incomplete codons, T or TA. The phylogenetic reconstruction places M. mustelus within the genus Mustelus, with the closest relationship to the placental species, M. griseus. This mitogenome provides valuable information to further unravel the evolution of alternate reproductive modes within the genus.

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.
