Complete sequence of mitochondrial DNA of a deep-sea holothurian species of the genus Synallactes (Synallactida: Synallactidae).

ABSTRACT: One complete mitochondrial genome (mitogenome) was determined for a deep-sea holothurian species of the genus Synallactes (Synallactida: Synallactidae). The mitochondrial genome size of the sea cucumber was 15,920 bp. The sequence contains 2 ribosomal RNA genes (12S and 16S), 22 transfer RNA genes, and 13 protein-coding genes, as found in most previously determined holothurian mitogenomes. The A + T content of the complete mitochondrial genome sequence was 64.45%. The base composition showed a tendency of AT. The resulted maximum likelihood (ML) tree of Holothuroidea supported that Synallactes sp. is a species of Synallactida.

The complete mitochondrial genome of a deep sea ophiuroid of the genus Amphiura (Ophiuroidea: Amphiuridae).

Project description:Amphiura is a widely distributed genus of Ophiuroidea from various environment, play an important role in evolution. Here, we reported a complete mitochondrial genome of Amphiura sp. which was collected from a deep sea seamount in the West Pacific. The mitogenome is 15,457 in length, including 13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes. All genes are arranged in the same order of published mitogenomes in the same genus. The phylogenetic analysis support monophyly of the family Amphiuridae but not for the genus Amphiura.

Genomic Characterization of a Novel Tenericutes Bacterium from Deep-Sea Holothurian Intestine.

Project description:Intestinal bacterial communities are highly relevant to the digestion, nutrition, growth, reproduction, and immunity of animals, but little is known about the composition and function of intestinal microbiota in deep-sea invertebrates. In this study, the intestinal microbiota of six holothurian Molpadia musculus were investigated, showing that their midguts were predominantly occupied by Izemoplasmatales bacteria. Using metagenomic sequencing, a draft genome of 1,822,181 bp was successfully recovered. After comparison with phylogenetically related bacteria, genes involved in saccharide usage and de novo nucleotide biosynthesis were reduced. However, a set of genes responsible for extracellular nucleoside utilization and 14 of 20 amino acid synthesis pathways were completely retained. Under oligotrophic condition, the gut-associated bacterium may make use of extracellular DNA for carbon and energy supplement, and may provide essential amino acids to the host. The clustered regularly interspaced short palindromic repeat (CRISPR) and restriction-modification (RM) systems presented in the genome may provide protection against invading viruses. A linear azol(in)e-containing peptide gene cluster for bacteriocin synthesize was also identified, which may inhibit the colonization and growth of harmful bacteria. Known virulence factors were not found by database searching. On the basis of its phylogenetic position and metabolic characteristics, we proposed that the bacterium represented a novel genus and a novel family within the Izemoplasmatales order and suggested it be named "Candidatus Bathyoplasma sp. NZ". This was the first time describing host-associated Izemoplasmatales.

Complete Genome Sequence of the Deep-Sea Bacterium Psychromonas Strain CNPT3.

Project description:Members of the genus Psychromonas are commonly found in polar and deep-sea environments. Here we present the genome of Psychromonas strain CNPT3. Historically, it was the first bacterium shown to piezoregulate the composition of its membrane lipids and to have a higher growth rate at 57 megapascals (MPa) than at 0.1 MPa.

Complete mitochondrial genome sequence of Labriocimbex sinicus, a new genus and new species of Cimbicidae (Hymenoptera) from China.

Project description:Labriocimbex sinicus Yan & Wei gen. et sp. nov. of Cimbicidae is described. The new genus is similar to Praia Andre and Trichiosoma Leach. A key to extant Holarctic genera of Cimbicinae is provided. To identify the phylogenetic placement of Cimbicidae, the mitochondrial genome of L. sinicus was annotated and characterized using high-throughput sequencing data. The complete mitochondrial genome of L. sinicus was obtained with a length of 15,405 bp (GenBank: MH136623; SRA: SRR8270383) and a typical set of 37 genes (22 tRNAs, 13 PCGs, and two rRNAs). The results demonstrated that all PCGs were initiated by ATN codon, and ended with TAA or T stop codons. The study reveals that all tRNA genes have a typical clover-leaf secondary structure, except for trnS1. Remarkably, the secondary structures of the rrnS and rrnL of L. sinicus were much different from those of Corynis lateralis. Phylogenetic analyses verified the monophyly and positions of the three Cimbicidae species within the superfamily Tenthredinoidea and demonstrated a relationship as (Tenthredinidae + Cimbicidae) + (Argidae + Pergidae) with strong nodal supports. Furthermore, we found that the generic relationships of Cimbicidae revealed by the phylogenetic analyses based on COI genes agree quite closely with the systematic arrangement of the genera based on the morphological characters. Phylogenetic tree based on two methods shows that L. sinicus is the sister group of Praia with high support values. We suggest that Labriocimbex belongs to the tribe Trichiosomini of Cimbicinae based on adult morphology and molecular data. Besides, we suggest to promote the subgenus Asitrichiosoma to be a valid genus.

Complete Mitochondrial Genome of Three Species of the Genus Microtus (Arvicolinae, Rodentia).

Project description:The 65 species of the genus Microtus have unusual sex-related genetic features and a high rate of karyotype variation. However, only nine complete mitogenomes for these species are currently available. We describe the complete mitogenome sequences of three Microtus, which vary in length from 16,295 bp to 16,331 bp, contain 13 protein-coding genes (PCGs), two ribosomal RNA genes, 22 transfer RNA genes and a control region. The length of the 13 PCGs and the coded proteins is the same in all three species, and the start and stop codons are conserved. The non-coding regions include the L-strand origin of replication, with the same sequence of 35 bp, and the control region, which varies between 896 bp and 930 bp in length. The control region includes three domains (Domains I, II and III) with extended termination-associated sequences (ETAS-1 and ETAS-2) in Domain I. Domain II and Domain III include five (CSB-B, C, D, E and F) and three (CSB-1, CSB-2, and CSB-3) conserved sequence blocks, respectively. Phylogenetic reconstructions using the mitochondrial genomes of all the available Microtus species and one representative species from another genus of the Arvicolinae subfamily reproduced the established phylogenetic relationships for all the Arvicolinae genera that were analyzed.
