Complete mitochondrial genome of the fish leech Zeylanicobdella arugamensis.

ABSTRACT: The complete mitochondrial genome of the fish leech Zeylanicobdella arugamensis from China has been determined for the first time in this study. It was 16,161?bp in length and consisted of 22 tRNA genes, two rRNA genes, 13 protein-coding genes (PCGs), and one control region. The nucleotide base content of Z. arugamensis mitogenome was 35.5% A, 10.4% C, 10.4% G, and 43.7% T. Start codon ATG was used in PCGs, while most of the termination codons are incomplete T or TA. The tRNA genes were ranged from 59?bp (tRNA-Arg and tRNA-Glu) to 69?bp (tRNA-Gln and tRNA-Cys) in length. The phylogenetic tree was constructed and suggested that Z. arugamensis has closer relationship to the Poecilobdella manillensis, Erpobdella octoculata, Hirudo hipponia, Whitmania acranulata, Whitmania pigra, Whitmania Laevis, Hirudo verbaba, and Hirudo medicinalis, and that they constitute a sister group.

The complete mitochondrial genome of Luehdorfia chinensis Leech (Lepidoptera: Papilionidae) from China.

Project description:The complete mitochondrial genome of Luehdorfia chinensis that is endemic to China is determined. The circular genome is 15 550 bp in length and comprises 13 protein-coding genes (PCGs), 22 tRNAs, two rRNA gene and a control region. Gene order is identical to that of the putative ancestral arrangement of insects. The nucleotide composition of heavy strand is A (40.3%), C (11.2%), T (41.1%) and G (7.3%). All PCGs start with a typical ATN codon except for the gene COI that uses AAC as the start codon. Bayesian analyses support the monophyly of genus Papilio and the sister relationship of Luehdorfia chinensis and L. taibai.

The complete mitochondrial genome of Eastern paradise fish (Polynemus dubius).

Project description:Eastern paradise fish, Polynemus dubius (also called P. longipectoralis), lives in rivers of the Southeastern Asia. Although its whole genome is not available, we first obtained its complete mitochondrial genome through next-generation sequencing. The length of its mitochondrial genome is 16 568 bp with 13 protein-coding genes, two rRNA genes, 22 tRNA genes and one control region. The distribution and arrangement of genes in the mitochondrial genome are similar to those of other vertebrates. The GC content is 43.08%, similar to the reported P. paradiseus. A phylogenetic tree was constructed to compare with nine related species by using MEGA 6.0. Through phylogenetic analysis, the relationship of species within the Polynemus genus is determined.

Complete mitochondrial genome of the freshwater fish, Carassioides acuminatus (Cypriniformes, cyprinidae).

Project description:In this study, the complete mitochondrial genome of Carassioides acuminatus was first sequenced and annotated. The entire mitogenome is 16,579bp in length, which consists of 13 protein-coding genes (PCGs), 22 transfer RNA genes, 2 ribosomal RNA genes, and a control region (D-loop). The overall nucleotide composition of the C. acuminatus mitochondrial genome shows an obvious anti-G bias. The accuracy of the fresh sequences was verified by phylogenetic analysis. The complete mitochondrial genome of C. acuminatus is useful to population genetics and molecular systematics.

Complete mitochondrial genome of Mekong fighting fish, Betta smaragdina (Teleostei: Osphronemidae).

Project description:Mekong fighting fish (Betta smaragdina) are found in Northeast Thailand. A complete mitochondrial genome (mitogenome) of B. smaragdina was assembled and annotated. Mitogenome sequences were 16,372 bp in length, with slight AT bias (59.8%), containing 37 genes with identical order to most teleost mitogenomes. Phylogenetic analysis of B. smaragdina showed closer relationship with B. splendens and B. mahachaiensis as the bubble-nesting group, compared to the mouthbrooder group (B. apollon, B. simplex, and B. pi). Results will allow the creation of a reference annotated genome that can be utilized to sustain biodiversity and eco-management of betta bioresources to improve conservation programs.

The complete mitochondrial genome of golden yellow snakehead fish, Channa argus.

Project description:We sequenced and characterized the complete mitochondrial genome of golden yellow snakehead fish, Channa argus. The mitogenomes contained the typical complement of 13 protein-coding genes, 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs), and a non-coding control region. They share the same gene arrangement pattern that was identical with most vertebrates. The entire mitochondrial DNA molecule of golden yellow snakehead fish was 16,558 bp long. All information reported in this article will be a useful source of sequence information for general molecular and evolutionary studies of the family Channidae.

Complete mitochondrial genome of near threatened fish species Osteobrama belangeri (Cypriniformes: Cyprinidae).

Project description:The complete mitochondrial genome of Osteobrama belangeri was obtained, using Illumina high-throughput NextSeq 500 with 2 × 150 bp sequencing of mitochondrial DNA. The mitochondrial genome of O. belangeri was 16,602 bp in length (GenBank Accession No. KY887473), comprised of 13 protein coding genes, 22 tRNA genes, 2 rRNA genes and a control region, i.e. D-loop. In present mitogenome, 11 short sequence repeats were identified and validated in silico. The arrangement of genes was found identical to other Cypriniformes fish mitogenomes, available in NCBI database. Phylogenetic relationship established in the present study also supported that genus Osteobrama is member of subfamily Cyprininae (tribe: smiliogastrini) not Cultrinae, which provide useful insights into taxonomic status of the genus.
