The complete mitochondrial genome of the Antarctic marbled rockcod, Notothenia rossii (Perciformes, Nototheniidae).

ABSTRACT: The complete mitochondrial genome of Notothenia rossii was obtained using PacBio Sequel long-read sequencing platform. The mitogenome of N. rossii was circular form and 18,274 bp long, which consists of 13 protein-coding genes, 24 tRNAs, 2 rRNAs, and non-coding control region. Particularly, we found duplicated tRNA^Thr and tRNA^Pro in addition to the typical 22 tRNAs. The phylogenetic tree revealed that N. rossii was most closely related to N. coriiceps among species in the Nototheniidae clade within the suborder Notothenioidei.

The complete mitochondrial genome of Trematomus loennbergii (Perciformes, Nototheniidae).

Project description:The complete mitochondrial genome of Trematomus loennbergii was studied using NGS technology with PacBio platform. The mitochondrial genome size was 19,374bp and it had 13 protein-coding genes, 22 tRNAs and 2 rRNAs. There were 4 types of stop codons which were TAA, TAG, AGG and T(AA) but start codon type was only one (ATG). The contents of GC were 44.09% and AT contents were 55.91%. To conduct phylogenetic analysis, 12 species in 3 families were used. The result suggested that T. loennbergii was close to Pagothenia borchgrevinki in Nototheniidae.

The complete mitochondrial genome of Gobionotothen gibberifrons (Perciformes, Nototheniidae).

Project description:The humped rockcod, Gobionotothen gibberifrons, is an Antarctic fish of the genus Gobionotothen in the family Nototheniidae and order Perciformes. To date, little biological information has been recorded about the genus Gobionotothen. Here, we report the first complete mitogenome of the genus Gobionotothen. The mitochondrial genome of G. gibberifrons is 18,631 bp in length, comprising 13 protein-coding genes, 24 tRNA genes (trnP-UGG and trnT-UGU were duplicated), 2 rRNA genes, and non-coding control regions. The base composition was 53.74% for A + T and 46.26% for G + C. This new mitochondrial genome of G. gibberifrons provides basic information for further phylogenetic analysis, suggesting the necessity to exploit a variety of newly discovered mitogenome sequences to infer inconclusive evolutionary relationships in Antarctic fishes.

The complete mitochondrial genome of a marbled eelpout Lycodes raridens (Perciformes: Zoarcidae).

Project description:In this study, the complete mitochondrial genome of the marbled eelpout, Lycodes raridens Taranetz & Andriashev, 1937 was sequenced using the primer walking method. The mitogenome was 16,569 bp in length and encoded with 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and one Non-Coding Region. The overall nucleotide composition of L. raridens is 25.5%, 25.3%, 18.7%, and 30.5% for A, T, G, and C, respectively. Phylogenetic analysis using the ML method showed that L. raridens was clustered into one branch with L. ygreknotatus and L. toyamensis.

The complete mitochondrial genome sequence and gene organization of Trematomus bernacchii (Perciformes: Nototheniidae) with phylogenetic consideration.

Project description:In this study, the complete mitochondrial DNA sequence was obtained from Trematomus bernacchii. The full length of mitogenome was 16 018 bp, including 20 transfer RNA genes, a 16S ribosomal RNA genes and an incomplete 12S rRNA, 12 protein-coding genes and an incomplete ND6 protein-coding gene, and 2 non-coding regions: control region (D-loop) and origin of light-strand (L-strand) replication (OL). Most genes were located on the heavy-strand (H-strand), while ND6 and seven tRNA genes were located on the L-strand. T. bernacchii's mitogenome was comprised of 24.52% for A, 25.44% for C, 20.38% for G and 29.66% for T, with a higher A + T content (54.18%). From the NJ phylogenetic tree, it revealed that T. bernacchii's was genetically closest to species Dissostichus eleginoides among seven species within suborder Notothenioidei. This study could lay the foundation for the future studies in species identification, taxonomic status, molecular systematics, stock evaluation and conservation genetics for T. bernacchii's.

Comparison of Fatty Acid Contents and MMP-1 Inhibitory Effects of the Two Antarctic Fish, Notothenia rossii and Champsocephalus gunnari

Project description:Total fatty-acid (FA) contents of different organs (stomach, liver, brain, and skin) of two Antarctic fish, marbled rockcod (Notothenia rossii) and mackerel icefish (Champsocephalus gunnari), were examined using gas chromatography–mass spectrometry (GC–MS). N. rossii possessed higher contents of total omega-3, where eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), the most represented omega-3 FAs, were distributed throughout all parts of the fish. The highest level of EPA was observed in the skin and that of DHA was observed in the brain of N. rossii. C. gunnari showed organ peculiarity in that most of the omega-3 FAs were found in stomach and skin. Specifically, the highest levels of EPA and DHA were both observed in the stomach. Although N. rossii and C. gunnari both inhabit the Antarctic Southern Oceans, their characteristics in terms of the composition of fatty acids were shown to vary. The extracts were also evaluated for matrix metalloproteinase-1 (MMP-1)-inhibitory activities in UVB-induced human dermal fibroblasts, where extracts of the skin and liver of N. rossii showed the most significant inhibition upon MMP-1 production. These findings provide experimental evidence that the extracts of the Antarctic fish could be utilized as bioactive nutrients, particularly in the enhancement of skin health.
