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. [ABSTRACT FROM AUTHOR]

In this study, the complete mitochondrial DNA genome sequence of Rastrelliger kanagurta has been determined. The mitogenome was 16,537 bp in length. It consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and 2 non-coding regions. The A+T content of the mitochondrial genome of R. kanagurta was 52.29%, and the content was 26.92% for A, 30.67% for C, 17.03% for G, and 25.37% for T. The complete mitogenome of R. kanagurta can provide an important data for the studies on molecular systematics, species identification, stock evaluation, conservation genetics, and evolutionary adaptation mechanisms.

In this study, we obtained the complete mitochondrial genome sequence ofSphyraena jelloand analyzed its phylogenetic position. The complete mitogenome ofS. jellois 16 699 bp in length, consisting of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and a control region. Among the 37 genes, 28 were encoded on heavy strand, while 9 were encoded on light strand. The overall base composition was 28.97% for A, 16.14% for G, 29.64% for C, and 25.25% for T, with a higher A + T content (54.22%). The phylogenetic analysis based on 13 concatenated protein-coding genes suggested thatS. jellois a sister species toSphyraena barracudain the family Sphyraenidae. This result should be useful for understanding the genetic structure, molecular evolution, and phylogeny ofS. jelloand related species. [ABSTRACT FROM AUTHOR]
