Mitochondrial genome of Sabella spallanzanii (Gmelin, 1791) (Sabellida: Sabellidae).

ABSTRACT: We report the mitochondrial genome of Sabella spallanzanii, an invasive Mediterranean sabellid introduced to Australia and New Zealand. The mitogenome is 15,581 bp long and consists of 38 genes, including 13 protein coding genes, two rRNA genes, and 23 tRNA genes. It shows deviations from the putative annelid ground pattern, such as gene order re-arrangements and regions encoding on the negative strand. It is, however, very different from the mitogenome of the closely related serpulid, Spirobranchus giganteus. Phylogenetic analyses of the mitochondrial genes support a sister relationship of Sabella spallanzanii and Spirobranchus giganteus.

The complete mitochondrial genome of Ternate False Fusus Brunneifusus ternatanus Gmelin, 1791 (Neogastropoda: Buccinoidea: Melongenidae) obtained using next-generation sequencing.

Project description:In this paper, the complete mitochondrial genome of Ternate False Fusus Brunneifusus ternatanus Gmelin, 1791 was determined and characterized for the first time from the South China Sea. Our results showed that the length of the whole mitogenome of B. ternatanus was 16,254 bp and the mitogenome consisted of 22 tRNA genes, 13 protein-coding genes (PCGs), and 2 rRNA genes. Furthermore, the nucleotide composition of this mitogenome is significantly biased with G + C contents of 31.85% (the base content was 30.38% A, 16.17% G, 37.77% T, and 15.68% C). All PCGs shared ATG as the initiation codon, and stop codon of TAA or TAG, with the exception of COX2 which ended with a single T. The phylogenetic tree showed that B. ternatanus was first clustered with Hemifusus tuba, and from a single distinct cluster. The new complete mitochondrial genome provides new insight into the phylogenetic of Melongenidae and its evolution.

Genomic and 16S metabarcoding data of Holothuria tubulosa Gmelin, 1791.

Project description:Holothuria tubulosa Gmelin, 1791 is an edible sea cucumber species widespread in the Mediterranean Sea with ecological and increasing economic importance. Genome data of holothurian species is limited and the availability of genomic data resources is crucial in understanding their biology and adaptability mechanisms. This dataset presents the raw genome sequence data of H. tubulosa sequenced on an Illumina NextSeq 2000 platform. Genome size estimation was performed based on k-mer frequency approach. Additionally, the bacterial microbiome in the stomach and intestine of H. tubulosa collected from the Strymonian Gulf (North Aegean Sea, Greece) through 16S rRNA amplicon metabarcoding sequencing is reported. Sequencing was performed on an Illumina MiSeq platform. Analysis was conducted using the QIIME2 software package, the DADA2 algorithm and a trained classifier for taxonomy assignment. The datasets presented in this work serve as valuable resources for a comprehensive investigation of H. tubulosa at the genome level and for comparative genomics and echinoderms gut microbial studies.

A new species of Claviramus (Annelida, Sabellida, Sabellidae) from the Ariake Inland Sea, Kyushu, Japan.

Project description:A new species of the sabellid polychaete genus Claviramus Fitzhugh, 2002, is described from Ariake Inland Sea, Kyushu, Japan. Claviramus is a small genus, composed of three species worldwide. Its distinctive feature is the presence of foliaceous flanges at the distal ends of the radioles. Claviramus kyushuensis sp. nov. here described is characterized by the presence of a glandular ridge on chaetiger 2, glandular shields on the abdomen, thoracic uncini bidentate, and the presence of a short, distal filament in some radioles. A key and a comparative table of diagnostic characters for species of Claviramus are provided.

Three species of Amphicorina (Annelida, Sabellida, Sabellidae) from Japan, with descriptions of two new species.

Project description:We describe two new species and redescribe one in the polychaete genus Amphicorina Claparède, 1864 (Sabellidae) from Hokkaido, Japan. Amphicorina ascidicolasp. n. differs from its 38 congeners chiefly in the reduction of the collar, but also in having three pairs of radioles, one pair of ventral radiolar appendages, a bifurcate ventral lobe on the anterior peristomial ring, six abdominal chaetigers, and a large anterior tooth on the abdominal uncini. Amphicorina ezoensissp. n. has a crenulated collar, three pairs of radioles, and more than eight (12) abdominal chaetigers; Amphicorina ezoensis shares these character states with Amphicorina anneae (Rouse, 1994), Amphicorina eimeri (Langerhans, 1880), and Amphicorina persinosa (Ben-Eliahu, 1975), but differs from them in having two pairs of ventral radiolar appendages and a non-oblique collar. Amphicorina mobilis (Rouse, 1990) was previously known only from the type locality (New South Wales, Australia), but we identify our Japanese material as conspecific on the basis of morphological and molecular similarity.

Mitochondrial genome of Pseudopotamilla reniformis (Annelida: Sabellidae).

Project description:Here, we report the complete mitochondrial genome of sabellid Pseudopotamilla reniformis (Bruguière, 1789) (16,408 bp) and comprised of two ribosomal RNAs, the ubiquitous set of 13 protein-coding sequences, and 22 tRNAs. The order of protein-coding genes is consistent with the proposed conserved pattern, which contradicts recent discovery in other members of the family (Sabella spallanzanii in Daffe et al., 2021 and Bispira melanostigma in Hornfeck et al., 2022).

Significant genetic differentiation among populations of Anomalocardia brasiliana (Gmelin, 1791): A bivalve with planktonic larval dispersion.

Project description:Four Brazilian populations of Anomalocardia brasiliana were tested for mutual genetic homogeneity, using data from 123 sequences of the mtDNA cytochrome oxidase c subunit I gene. A total of 36 haplotypes were identified, those shared being H3 (Canela Island, Prainha and Acupe) and both H5 and H9 (Prainha and Acupe). Haplotype diversity values were high, except for the Camurupim population, whereas nucleotide values were low in all the populations, except for that of Acupe. Only the Prainha population showed a deviation from neutrality and the SSD test did not reject the demographic expansion hypothesis. Fst values showed that the Prainha and Acupe populations represent a single stock, whereas in both the Canela Island and Camurupim stocks, population structures are different and independent. The observed structure at Canela Island may be due to the geographic distance between this population and the remainder. The Camurupim population does not share any haplotype with the remaining populations in northeastern Brazil. The apparent isolation could be due to the rocky barrier located facing the mouth of the Mamanguape River. The results highlight the importance of wide-scale studies to identify and conserve local genetic diversity, especially where migration is restricted.

Phylogeography and genetic differentiation among populations of the Moon Turban Snail Lunella granulata Gmelin, 1791 (Gastropoda: Turbinidae).

Project description:We examined the genetic variation and phylogeographic relationships among 10 populations of Lunella granulata from mainland China, Penghu Archipelago, Taiwan Island, and Japan using mitochondrial COI and 16S markers. A total of 45 haplotypes were obtained in 112 specimens, and relatively high levels of haplotype diversity (h = 0.903) and low levels of nucleotide diversity (? = 0.0046) were detected. Four major phylogenetic lineage clusters were revealed and were concordant with their geographic distribution, agreeing with the haplotype network. These results suggested that geographic barrier isolating effects were occurring among the populations. This hypothesis was also supported by a significant genetic differentiation index (FST = 0.709) and by a spatial analysis of molecular variance (SAMOVA) analysis. A mismatch distribution analysis, neutrality tests and Bayesian skyline plots found a single significant population expansion. This expansion occurred on the coast of mainland China before 20-17 ka. Consequently, although the dispersal ability of the planktonic stage and the circulation of ocean currents generally promote genetic exchanges among populations, L. granulata has tended to maintain distinct genetic groups that reflect the respective geographic origins of the constituent lineages. Although the circulation of ocean currents, in principle, may still play a role in determining the genetic composition of populations, long-distance migration between regions is difficult even at the planktonic stage.

Identification and Characterization of Three New Antimicrobial Peptides from the Marine Mollusk Nerita versicolor (Gmelin, 1791).

Project description:Mollusks have been widely investigated for antimicrobial peptides because their humoral defense against pathogens is mainly based on these small biomolecules. In this report, we describe the identification of three novel antimicrobial peptides from the marine mollusk Nerita versicolor. A pool of N. versicolor peptides was analyzed with nanoLC-ESI-MS-MS technology, and three potential antimicrobial peptides (Nv-p1, Nv-p2 and Nv-p3) were identified with bioinformatical predictions and selected for chemical synthesis and evaluation of their biological activity. Database searches showed that two of them show partial identity to histone H4 peptide fragments from other invertebrate species. Structural predictions revealed that they all adopt a random coil structure even when placed near a lipid bilayer patch. Nv-p1, Nv-p2 and Nv-p3 exhibited activity against Pseudomonas aeruginosa. The most active peptide was Nv-p3 with an inhibitory activity starting at 1.5 µg/mL in the radial diffusion assays. The peptides were ineffective against Klebsiella pneumoniae, Listeria monocytogenes and Mycobacterium tuberculosis. On the other hand, these peptides demonstrated effective antibiofilm action against Candida albicans, Candida parapsilosis and Candida auris but not against the planktonic cells. None of the peptides had significant toxicity on primary human macrophages and fetal lung fibroblasts at effective antimicrobial concentrations. Our results indicate that N. versicolor-derived peptides represent new AMP sequences and have the potential to be optimized and developed into antibiotic alternatives against bacterial and fungal infections.

The complete mitochondrial genome of pronghorn spiny lobster Panulirus penicillatus (Olivier, 1791).

Project description:In this paper, we determined and characterized the complete mitochondrial genome of Pronghorn spiny lobster Panulirus penicillatus for the first time from South China Sea. The P. penicillatus mitogenome is 15,671 bp long, and consists of 22 tRNA genes, 2 rRNA genes, 13 protein-coding genes (PCGs), and 1 control region. The nucleotide composition of P. penicillatus mitogenome is significantly biased (A, G, T, and C was 33.62, 13.32, 32.31, and 20.75%, respectively) with A + T contents of 65.93%. Almost PCGs used a standard initiation codon or stop codon, except COX2, ND3, ND4 and ND1 were terminated with an incomplete stop codon T and ND5 ended with TA. One microsatellite (C)12 was identified in the control region of P. penicillatus mitogenome sequences. Phylogenetic tree showed that P. penicillatus was first clustered with P. polyphagus and P. versicolor.
