Abstract

The complete mitochondrial genome of Chionodraco hamatus was obtained, which was 17 457 bp in length. This genome consists of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and a putative control region. Of the 37 genes, 28 were encoded by heavy strand, while 9 were encoded by light strand. Overall base composition of mitogenome is estimated to be 26.38% for A, 17.44% for G, 26.00% for T, 30.18% for C, respectively, with a slight A + T bias (52.38%). The phylogenetic analysis based on 13 concatenated protein-coding genes suggested that C. hamatus as a sister species to Chionodraco myersi was clustered in family Chionodraco. The complete mitochondrial genome sequence of C. hamatus could provide a basic data for the studies on evolution for low temperature adaptability, population structure, molecular systematic, stock evaluation and conservation genetics.

Abstract

In this study, the complete mitochondrial genome of Neopagetopsis ionah was obtained, which was 17,634 bp including two ribosomal RNAs, 13 protein-coding genes, 22 transfer RNAs, and a non-coding control region. In 13 protein-coding genes, there types of initiation codon (ATC, ATG, and GTG) and four types of stop codons (TAA, TAG, TA, and T) were identified. Among the 22 transfer RNAs, eight tRNAs were encoded by L-strand. The length of D-loop was 1519 bp and its contents of A, T, C, and G were 26.9%, 27.6%, 17.5%, and 30%, respectively. The complete mtDNA sequences of N. ionah and other 13 species were used to reconstruct the phylogenetic tree suggested that N. ionah was closest to some species of Channichthyidae. The study would provide a basic data for further research on population structure, conservation genetics and molecular evolution of N. ionah. [ABSTRACT FROM AUTHOR]

Abstract

In this study, the complete mitochondrial genome of Chionodraco rastrospinosus was obtained, which was 17598 bp including 2 ribosomal RNAs, 13 protein-coding genes, 22 transfer RNAs, and a non-coding control region. The length of D-loop was 1332 bp and its contents of A, T, C, and G were 30.3%, 27.6%, 26.8%, and 15.3%. The complete mtDNA sequences of C. rastrospinosus and other 14 species were used to reconstruct the phylogenetic tree, suggested that C. rastrospinosus was closest to two species of Chionodraco. The study would provide a basic data for further research on population structure, conservation genetics and molecular evolution of C. rastrospinosus. [ABSTRACT FROM AUTHOR]

Abstract

The complete mitochondrial genome of Electrona carlsbergi was obtained, which was 18,282 bp in size and including 13 protein-coding genes, 2 ribosomal RNAs, 23 transfer RNAs and 1 control region. The overall nucleotide composition is 27.92% for A, 24.66% for T, 30.90% for C and 16.52% for G. Among 23 tRNA genes, 8 tRNAs were encoded on the L-strand. Further, the phylogenetic tree, which based on complete mtDNA sequences, revealed that the E. carlsbergi was genetically closest to species E. antarctica and Krefftichthys anderssoni. This study could provide a basic data for the studies on evolution for low temperature adaptability, stock evaluation and conservation genetics. [ABSTRACT FROM AUTHOR]

Abstract

Gymnodraco acuticepsis is an Antarctic fish living in the Southern Ocean. Until now, studies on G. acuticeps are still limited. As an Antarctic fish, obtaining and characterization of the mitochondrial genome of G. acuticeps will be important for elucidation of the mechanism of cold-adapting evolution in mitochondrion. In this study, we first isolated and characterized the mitochondrial genome sequence of G. acuticeps with 15,987 bp in length. It contained of 34 genes (12 protein-coding genes, 20 transfer RNA genes, 2 ribosomal RNA genes) and a partial putative control region. Gene organization and nucleotide composition of obtained mito-genome were similar to those of other Antarctic fish. Twenty-eight genes were encoded by heavy strand, while six genes were encoded by light strand. Further, the phylogenetic tree, which based on 12 protein-coding genes, revealed that the G. acuticeps was genetically closest to species Parachaenichthys charcoti among 18 species. We hope this work would be helpful for the population genetics and molecular evolution studies.
