    ABSTRACT: The complete mitochondrial genome (mitogenome) of the red-banded lobster, Metanephrops thomsoni (Decapoda, Astacidea, Nephropidae), is 19,835 bp in length and contains 13 protein-coding genes (PCGs), 2 ribosomal RNAs, 24 transfer RNAs (including additional copies of trnW and trnL1), and 2 control regions (CR). The mitogenome of M. thomsoni has 10 long intergenic sequences (71-237 bp) with a high AT content (70.0%). The two CRs show 59.6% similarity and have an identical sequence region with a length of 295 bp. The mitogenome of M. thomsoni shows a novel gene arrangement compared with the pancrustacean ground pattern and is identical to that of M. sibogae, except for the two additional tRNAs (trnW and trnL1). Phylogenetic tree from maximum likelihood analysis using the concatenated sequences of 13 PCGs depicted M. thomsoni as one of the members of the superfamily Nephropoidea within Astacidea.

    ABSTRACT: The present-day genetic structure of a species reflects both historical demography and patterns of contemporary gene flow among populations. To precisely understand how these factors shape current population structure of the northwestern (NW) Pacific marine gastropod, Thais clavigera, we determined the partial nucleotide sequences of the mitochondrial COI gene for 602 individuals sampled from 29 localities spanning almost the whole distribution of T. clavigera in the NW Pacific Ocean (~3,700 km). Results from population genetic and demographic analyses (AMOVA, ΦST-statistics, haplotype networks, Tajima's D, Fu's FS, mismatch distribution, and Bayesian skyline plots) revealed a lack of genealogical branches or geographical clusters, and a high level of genetic (haplotype) diversity within each of studied population. Nevertheless, low but significant genetic structuring was detected among some geographical populations separated by the Changjiang River, suggesting the presence of geographical barriers to larval dispersal around this region. Several lines of evidence including significant negative Tajima's D and Fu's FS statistics values, the unimodally shaped mismatch distribution, and Bayesian skyline plots suggest a population expansion at marine isotope stage 11 (MIS 11; 400 ka), the longest and warmest interglacial interval during the Pleistocene epoch. The lack of genetic structure among the great majority of the NW Pacific T. clavigera populations may be attributable to high gene flow by current-driven long-distance dispersal of prolonged planktonic larval phase of this species.

    ABSTRACT: Acanthocephala is a relatively small, but distinct obligate parasitic group that includes 4 classes Archiacanthocephala, Palaeacanthocephala, Polyacanthocephala, and Eoacanthocephala. The phylogenetic relationships of acanthocephalans are mainly based on nuclear ribosomal genes. In this study, we determined the complete mitochondrial genome sequence of Southwellina hispida (Palaeacanthocephala: Polymorphida), and used this genome sequence along with other platyzoan species (including syndermatan groups) to assess its phylogenetic position within Acanthocephala. The S. hispida mtDNA is a 14,742bp circular molecule that contains 36 genes (lacking atp8) encoded in the same direction. Phylogenetic analyses of amino acid sequences for 12 protein-coding genes suggested palaeacanthocephalan species to be monophyletic, and this group to be sister to Eoacanthocephala. These results confirm other morphological and molecular data supporting Palaeacanthocephalan monophyly. Copyright © 2015. Published by Elsevier Ireland Ltd.

    ABSTRACT: Abstract Slipper lobsters are a unique group of decapod crustaceans; they have cylindrical or flattened bodies and belong to the family Scyllaridae. The genus Ibacus (Leach, 1815) (Achelata, Scyllaridae, Ibacinae) consists of eight recognized species to date, all of which occur in the Indo-West Pacific Ocean and are commercially important seafood species. The complete mitochondrial genome of the Japanese fan lobster Ibacus ciliatus (Von Siebold, 1824) is 15,696 bp in size and consists of 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs, and a control region of 783 bp. The base composition of I. ciliatus is 35.8% A, 34.7% T, 19.0% C, and 10.5% G, with an overall AT content of 70.5%. The mitogenome of I. ciliatus was found to have gene arrangement and transcriptional polarity identical to that of the American lobster Homarus americanus, showing the pancrustacean ground pattern. Here, we present the complete mitogenome sequence of I. ciliatus; it is the first mitogenome information from the subfamily Ibacinae, and represents the second for the family Scyllaridae.

    ABSTRACT: Abstract The violet-spotted reef lobster Enoplometopus debelius Holthuis, 1983 (Decapoda, Astacidea, Enoplometopidae) is found in the tropical reef areas of the Indo-Pacific region, and is a highly prized and very popular species in the aquarium trade industry. The complete mitochondrial genome of E. debelius has 15,641 base pairs consisting of 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs, and a control region of 746 bp. The base composition of E. debelius is 36.4% A, 35.3% T, 18.1% C, 10.3% G, and the species has an AT content of 71.7%. The E. debelius mitogenome was found to have a gene arrangement and transcriptional polarity identical to that of the Homarus americanus mitogenome, a representative of the arthropod ground pattern. Here, we present the complete mitogenome sequence of E. debelius, which is the first in the superfamily Enoplometopoidea. These data will provide a useful molecular resource for the phylogenetic study of the infraorder Astacidea/order Decapoda.

    ABSTRACT: The Federated States of Micronesia consists of four states of Yap, Chuuk, Pohnpei and Kosrae, which are located in the West Pacific Ocean. In order to investigate molluscan fauna of Kosrae Island, field survey was made twice from 21st to 30th of January, 2011 and from 6th to 17th of January, 2012 for four localities including 10 intertidal and 14 subtidal zones of Kosrae Island. The mollusk samples collected were identified based on their morphological characteristics, comprising a total of 120 species from 30 families through this survey. In this study, we provided species list and illustrations for 120 species identified, and combined these with the previous record, resulting in a total of 208 species from 47 families in Kosrae Island.

    ABSTRACT: We determined the complete mitochondrial genome sequences for Bursaphelenchus mucronatus, one species of pinewood nematode. The genome is a circular-DNA molecule of 14,583bp (195bp smaller than its congener Bursaphelenchus xylophilus) and contains 12 protein-coding genes (lacking atp8), 22 tRNA genes, and 2 rRNA genes encoded in the same direction, consistent with most other nematodes. Based on sequence comparison of mtDNA genomes, we developed a PCR-based molecular assay to differentiate B. xylophilus (highly pathogenic) and B. mucronatus (relatively less virulent) using species-specific primers. The molecular identification system employs multiplex-PCR and is very effective and reliable for discriminating these Bursaphelenchus species, which are economically important, but difficult to distinguish based on morphology. The comparison of the mitochondrial genomes and molecular identification system of the two species of Bursaphelenchus spp. should provide a rich source of genetic information to support the effective control and management (quarantine) of the pine wilt disease caused by pinewood nematodes.

    ABSTRACT: The southern coast of Australia is composed of three distinct biogeographic provinces distinguished primarily by intertidal community composition. Several ecological mechanisms have been proposed to explain their formation and persistence, but no consensus has been reached. The marine clam Lasaea australis is arguably the most common bivalve on southern Australian rocky shores and occurs in all three provinces. Here, we tested if this species exhibits cryptic genetic structuring corresponding to the provinces and if so, what mechanisms potentially drove its divergence. Variation in two mitochondrial genes (16S and COIII) and one nuclear gene (ITS2) was assayed to test for genetic structuring and to reconstruct the clam's phylogenetic history. Our results showed that L. australis is comprised of three cryptic mitochondrial clades, each corresponding almost perfectly to one of the three biogeographic provinces. Divergence time estimates place their cladogenesis in the Neogene. The trident-like topology and Neogene time frame of L. australis cladogenesis are incongruent with Quaternary vicariance predictions: a two-clade topology produced by Pleistocene Bass Strait land bridge formation. We hypothesize that the interaction of the Middle Miocene Climate Transition with the specific geography of the southern coastline of Australia was the primary cladogenic driver in this clam lineage. Additional in-depth studies of the endemic southern Australian marine biota across all three provinces are needed to establish the generality of this proposed older framework for regional cladogenesis.

    ABSTRACT: We determined the complete mitochondrial (mt) genome sequence of the red king crab, Paralithodes camtschaticus (Decapoda, Anomura). P. camtschaticus is one of the largest arthropods and the most expensive commercially available gourmet seafood. The genome sequence of P. camtschaticus is 16,720 bp in size and its gene content, gene order, and transcriptional polarity are almost identical to those of the hermit crab Pagurus longicarpus, which is thought to be derived from a common ancestor. However, P. camtschaticus mtDNA showed tRNA translocation in two blocks compared to that of P. longicarpus. Prior to this study, complete mt genomes of only two species of Anomura have been reported. Thus, our genomic data will provide additional information for constructing the decapod phylogeny.

    ABSTRACT: Background The nematode infraorder Tylenchomorpha (Class Chromadorea) includes plant parasites that are of agricultural and economic importance, as well as insect-associates and fungal feeding species. Among tylenchomorph plant parasites, members of the superfamily Tylenchoidea, such as root-knot nematodes, have great impact on agriculture. Of the five superfamilies within Tylenchomorpha, one (Aphelenchoidea) includes mainly fungal-feeding species, but also some damaging plant pathogens, including certain Bursaphelenchus spp. The evolutionary relationships of tylenchoid and aphelenchoid nematodes have been disputed based on classical morphological features and molecular data. For example, similarities in the structure of the stomatostylet suggested a common evolutionary origin. In contrast, phylogenetic hypotheses based on nuclear SSU ribosomal DNA sequences have revealed paraphyly of Aphelenchoidea, with, for example, fungal-feeding Aphelenchus spp. within Tylenchomorpha, but Bursaphelenchus and Aphelenchoides spp. more closely related to infraorder Panagrolaimomorpha. We investigated phylogenetic relationships of plant-parasitic tylenchoid and aphelenchoid species in the context of other chromadorean nematodes based on comparative analysis of complete mitochondrial genome data, including two newly sequenced genomes from Bursaphelenchus xylophilus (Aphelenchoidea) and Pratylenchus vulnus (Tylenchoidea). Results The complete mitochondrial genomes of B. xylophilus and P. vulnus are 14,778 bp and 21,656 bp, respectively, and identical to all other chromadorean nematode mtDNAs in that they contain 36 genes (lacking atp8) encoded in the same direction. Their mitochondrial protein-coding genes are biased toward use of amino acids encoded by T-rich codons, resulting in high A+T richness. Phylogenetic analyses of both nucleotide and amino acid sequence datasets using maximum likelihood and Bayesian methods did not support B. xylophilus as most closely related to Tylenchomorpha (Tylenchoidea). Instead, B. xylophilus, was nested within a strongly supported clade consisting of species from infraorders Rhabditomorpha, Panagrolaimomorpha, Diplogasteromorpha, and Ascaridomorpha. The clade containing sampled Tylenchoidea (P. vulnus, H. glycines, and R. similis) was sister to all analyzed chromadoreans. Comparison of gene arrangement data was also consistent with the phylogenetic relationships as inferred from sequence data. Alternative tree topologies depicting a monophyletic grouping of B. xylophilus (Aphelenchoidea) plus Tylenchoidea, Tylenchoidea plus Diplogasteromorpha (Pristionchus pacificus), or B. xylophilus plus Diplogasteromorpha were significantly worse interpretations of the mtDNA data. Conclusions Phylogenetic trees inferred from nucleotide and amino acid sequences of mtDNA coding genes are in agreement that B. xylophilus (the single representative of Aphelenchoidea) is not closely related to Tylenchoidea, indicating that these two groups of plant parasites do not share an exclusive most recent common ancestor, and that certain morphological similarities between these stylet-bearing nematodes must result from convergent evolution. In addition, the exceptionally large mtDNA genome size of P. vulnus, which is the largest among chromadorean nematode mtDNAs sequenced to date, results from lengthy repeated segments in non-coding regions.

    ABSTRACT: We determined the complete mitochondrial (mt) genome sequence of the Japanese ghost shrimp Nihonotrypaea japonica (Ortmann 1891) (Crustacea, Decapoda, Axiidea). The N. japonica mt genome is first represented in infraorder Axiidea, which, together with infraorder Gebiidea, belonged to infraorder Thalassinidea until recently. The genome sequence of N. japonica is 15,274 bp in size, and the gene arrangement and transcriptional polarity are partially different from that of the Japanese mud shrimp, Upogebia major, which belongs to the infraorder Gebiidea. We present the mt genome of N. japonica, which could provide useful molecular information to construct a stable classification for infraorder Thalassinidea and to better understand the phylogenetic relationship of Thalassinidea with other decapod groups.

    ABSTRACT: Despite recent advance in mass sequencing technologies such as pyrosequencing, assessment of culture-independent microbial eukaryote community structures using universal primers remains very difficult due to the tremendous richness and complexity of organisms in these communities. Use of a specific PCR marker targeting a particular group would provide enhanced sensitivity and more in-depth evaluation of microbial eukaryote communities compared to what can be achieved with universal primers. We discovered that many phylum-or groupspecific single-nucleotide polymorphisms (SNPs) exist in small subunit ribosomal RNA (SSU rRNA) genes from diverse eukaryote groups. By applying this discovery to a known simple allele-discriminating (SAP) PCR method, we developed a technique that enables the identification of organisms belonging to a specific higher taxonomic group (or phylum) among diverse types of eukaryotes. We performed an assay using two complementary methods, pyrosequencing and clone library screening. In doing this, specificities for the group (ciliates) targeted in this study in bulked environmental samples were 94.6% for the clone library and 99.2% for pyrosequencing, respectively. In particular, our novel technique showed high selectivity for rare species, a feature that may be more important than the ability to identify quantitatively predominant species in community structure analyses. Additionally, our data revealed that a target-specific library (or ciliate-specific one for the present study) can better explain the ecological features of a sampling locality than a universal library.

    ABSTRACT: The Cymatium Roding, 1798 is a small- to large-sized marine gastropod genus. Three species has been reported thus far for Cymatium in the Korean waters. In general, Cymatium encausticum (Reeve, 1844) is known to occur in tropical seawaters including the Philippine Islands along with its congeners C. gutturnium, C. springsteeni, and C. exile. A single individual of the species was collected from Jejudo Island by SCUBA diving and morphological features were observed using a stereomicroscope. This is the first study to report the occurrence of Cymatium encausticum (Reeve, 1844) from the Korean waters, providing a detailed description of the species with the illustration for the shell morphology.

    ABSTRACT: An exponential growth of mitochondrial genome information has brought significant progress in understanding the organismal phylogeny and mitochondrial genome evolution for many metazoans including platyhelminth groups. In this study, we determined the complete mitochondrial genome sequence for Benedenia hoshinai, an ectoparasitic monogenean species, and compared it with its congener Benedenia seriolae. The complete mitochondrial genome is 13,554 bp in length and contains 12 protein-coding genes (lacking the atp8 gene), 2 rRNA genes, and 22 tRNA genes, all encoded in the same direction as found in all other platyhelminth species sequenced to date. The gene arrangement of B. hoshinai mtDNA is almost identical to B. seriolae, differing only by the translocation of trnT between cox1 and rrnL. It is unclear whether the shared position of trnT between B. hoshinai and Gyrodactylus represents evidence for their phylogenetic affinity; testing this hypothesis requires further mitogenomic evidence.

    ABSTRACT: A major concern regarding the collection and storage of biodiversity information is the inefficiency of conventional taxonomic approaches in dealing with a large number of species. This inefficiency has increased the demand for automated, rapid, and reliable molecular identification systems and large-scale biological databases. DNA-based taxonomic approaches are now arguably a necessity in biodiversity studies. In particular, DNA barcoding using short DNA sequences provides an effective molecular tool for species identification. We constructed a large-scale database system that holds a collection of 5531 barcode sequences from 2429 Korean species. The Korea Barcode of Life database (KBOL, http://koreabarcode.org) is a web-based database system that is used for compiling a high volume of DNA barcode data and identifying unknown biological specimens. With the KBOL system, users can not only link DNA barcodes and biological information but can also undertake conservation activities, including environmental management, monitoring, and detecting significant organisms.
