Abstract We present the complete mitochondrial genome of the Trachinotus ovatus in this study. The mitochondrial genome is 16,563 bp long and consists of 13 protein-coding genes, two rRNA genes, 22 tRNA genes and a control region. The gene order and composition of T. ovatus mitochondrial genome was similar to that of most other vertebrates. The nucleotide compositions of the light strand are 29.03% of A, 28.86% of C, 26.23% of T and 15.88% of G. With the exception of ND6 and eight tRNA genes, all other mitochondrial genes are encoded on the heavy strand. Two copies of tandem repeat sequence (56 bp) was observed in the 5′ end of the control region.

Abstract Using Ion Torrent next-generation sequencing (NGS) technology, we sequenced the complete mitochondrial genome (mitogenome) of black and reddish morphs of the coral trout Plectropomus leopardus. High-throughput sequencing generated a total of 958,614 sequence reads covering 164.80 Mb of two mitogenomes with a coverage of 4800X. Thirty-seven mitochondrial genes and gene order of P. leopardus was quite similar to that of other teleostean fishes. Most genes were either abutted or overlapped, and all the protein-coding genes began with an ATG start codon except for COX1 and ATP6. The number of stop codon was different for the black and reddish P. leopardus. Comparisons between the mitochondrial sequences of the two morphs revealed a total of 74 variable sites and one indel. Nucleotide diversity across protein-coding gene varied from 0.0006 (16s rRNA) to 0.0070 (Cytochrome b). As expected, the highest level of nucleotide diversity (0.0291) was detected in the control region. Our results demonstrate the NGS technology based on Ion torrent platform can be used to assemble the mitogenome of fish species.

Insulin-like growth factor (Igf) is the key regulator for development, growth, and reproduction. In most vertebrate species, the Igf family has two forms: Igf1 and Igf2. A novel form of Igf, termed Igf3, was recently discovered in fish. In the present study, we isolated igf3 from the orange-spotted grouper (Epinephelus coioides). The orange-spotted grouper igf3 consisted of a full-length cDNA of 1014 nucleotides with an open reading frame (ORF) of 597 bp, encoding for proteins of 199 amino acid residues in length. Tissue distribution analysis showed that igf1 widely expressed with the highest expression in the pituitary and liver. igf2 was expressed highly in all the tissues except the olfactory bulb, while igf3 showed the highest expression in the ovary, and moderate expression in brain areas. The expression profiles of three igf genes during the ovarian development and growth hormone (Gh) and human chorionic gonadotropin (hCG) treatment were also investigated. Three igf genes exhibited different expression patterns during the ovarian development, and showed different responses to the Gh and hCG treatments, appearing to play distinct roles in ovarian development. The present study provides further evidence for the existence of an intraovarian Igf system in orange-spotted grouper.

Huirong Yang; Zhenzhen Xie; Shuisheng Li; Xichao Wu; Cheng Peng; Yong Zhang; Haoran Lin

Abstract We present the complete mitochondrial genome of Epinephelus coioides in this study. The mitochondrial genome is 16,458 bp in length, containing 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region. All of them are encoded on the heavy strand except ND6 and 8 tRNA genes on the light strand. The nucleotide compositions of the light strand are 28.88% of G, 28.75% of T, 26.58% of A and 15.80% of C. All the protein-coding genes share ATG initiation codon except ATP6 with CTG and COXI with GTG, and four types of inferred termination codons are T (ND2, COXII, ND3, ND4 and Cytb), TA (COXIII), TAA (ND1, ATP8, ND4L, ND5, ATP6 and COXI) and TAG (ND6). There are 10 intergenic spacers, 5 gene overlaps and no tandem repeat sequence. Gene arrangement and distribution are consistent with the typical vertebrates.
