The complete mitogenome of Hyporhamphus quoyi was sequenced, which is a closed double-stranded circular molecule of 16,511 bp, and we analyzed the main features in terms of the genome organization, gene arrangement and codon usage. The overall base composition includes A(27.4%), T(26.0%), C(30.4%) and G(16.2%). Moreover, the 13 protein-coding genes (PCGs) encode 3804 amino acids in total, 12 of which use the initiation codon ATG except COI uses GTG, most of them have a complete stop codon, whereas Cytb ends with the incomplete stop codon represented as a single T. The phylogenetic tree based on the neighbor-Joining method was conducted to provide relationship within Beloniformes, based on 12 PCGs encoded by the heavy strand, the NJ tree demonstrated that H. quoyi has a closest relationship with Hyporhamphus intermedius , which could be a useful basis for propagation of this species.

“…The 13 protein-coding genes encode 3802 amino acids in total. All the PCGs use the initiation codon ATG except COI uses GTG, which is quite common in vertebrate mtDNA (Balakirev et al 2016;Du et al 2018;Zhu et al 2018a). Most of them have TAA or TAG as the stop codon, except COII, ND4 and Cytb shared incomplete stop codon (T), these incomplete termination codons were presumably completed as TAA by posttranscriptional polyadenylation (Ojala et al 1981).…”

Phylogenetic analysis of the complete mitochondrial genome of Hyporhamphus limbatus (Beloniformes; hemiramphidae)

The first complete mitochondrial (mt) genome of Hyporhamphus limbatus is reported herein, the gene composition and arrangement in H. limbatus mitogenome were identical to those of most vertebrates, which is 16,508 bp in length and contains 13 PCGs, two rRNA genes (12S rRNA and 16S rRNA), 22 tRNA genes, and a putative control region (CR) and one origin of replication on the light-strand (OL). Two start codon patterns and three stop codon patterns were found in protein-coding genes. Only the tRNA-Ser(AGY) could not fold into a typical cloverleaf secondary structure for lacking the dihydrouridine arm. A phylogenetic tree based on the neighbour-joining method was constructed to provide relationship within Beloniformes, which could be a useful basis for management of this species.

“…MH631014), within the range of other teleost mitogenomes. As in other vertebrate (Miya et al 2001;Du et al 2018;Zhu et al 2018a), it contains 13 PGGs, 2 ribosomal RNA genes (12S rRNA and 16S rRNA), 22 tRNA genes, and 2 main non-coding regions. The overall base composition is 28.5% A, 28.8% C, 27.1% Tand 15.6% G respectively, with a slight AT bias (55.6%).…”

Carinotetraodon travancoricus was classified as vulnerable on the IUCN Red List due to habitat loss and overharvesting for the aquarium trade. To gain its molecular information and thus contribute to help in conserving this vulnerable species, we determined the complete mitochondrial DNA of the C. travancoricus. The size of the molecule is 16,542 nucleotides, containing 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, a putative control region, and 1 origin of replication on the light-strand. The overall base composition includes C(28.8%), A(28.5%), T(27.1%), and G(15.6%). Moreover, the 13 PCGs encode 3800 amino acids in total. The result of the phylogenetic tree supports C. octofasciatus has a closest relationship with Tetraodon nigroviridis.
