Abstract It is largely unknown how living organisms—especially vertebrates—survive and thrive in the coldness, darkness high pressures of hadal zone. Here, we describe unique morphology genome Pseudoliparis swirei —a recently described snailfish species below a depth 6,000 m Mariana Trench. Unlike closely related shallow sea species, P. has transparent, unpigmented skin scales, thin incompletely ossified bones, an inflated stomach non-closed skull. Phylogenetic analyses show that diverged...
<p>Deep-sea chemosynthetic communities, including hydrothermal vents and cold seeps, harbour hundreds of endemic species currently threatened by deep-sea mining hydrocarbon extraction. The South China Sea (SCS), a semi-enclosed marginal sea with two well-investigated active seeps (Haima in the west Site F east), provides an opportunity to understand biogeography ecosystems. Here, we conducted extensive field surveys using Remotely Operated Vehicles (ROVs) collected specimens for...
Polycyclic aromatic hydrocarbons (PAHs) are priority environmental pollutants that cause adverse health effects. PAHs belong to endocrine signaling disruptors which children sensitive to. Recent evidence suggests PAH pollution alters the abundance of bacteria is associated with outcomes. The alteration and commensal microbiota by has never been connected pathways. To estimate risk disruption in daycare children, we measured from soil air eleven urban centres Finland. We analyzed yards'...
Vestimentiferan tubeworms that thrive in deep-sea chemosynthetic ecosystems rely on a single species of sulfide-oxidizing gammaproteobacterial endosymbionts housed specialized symbiotic organ called trophosome as their primary carbon source. While this simple symbiosis is remarkably productive, the host-symbiont molecular interactions remain unelucidated. Here, we applied an approach for situ single-cell fixation cold-seep tubeworm,
Hadal trenches are characterized by not only high hydrostatic pressure but also scarcity of nutrients and diversity viruses. Snailfishes, as the dominant vertebrates, play an important role in hadal ecology. Although studies have suggested possible reasons for tolerance snailfish to pressure, little is known about strategies employed cope with low-nutrient virus-rich conditions. In this study, gut microbiota was investigated. A novel bacterium named "Candidatus Mycoplasma liparidae" guts...
Abstract It is increasingly being recognized that tree species diversity has positive effects on forest ecosystem carbon (C) stock. However, at broad spatial scales, this relationship may depend climate conditions and mycorrhizal associations. Here, observations from 667 plots in subtropical China were used to investigate the of diversity, mean annual precipitation (MAP), temperature (MAT) type (arbuscular or ectomycorrhizal) C stock its components (tree stock, shrub layer herb litter root...
The gut microbiota is contributable to the adaptation and health of deep-sea organisms has been revealed be affected by many factors, especially host species diet. Here, we employed high-throughput sequencing 16S rDNA compare microbial composition diversity two hadal amphipod species, Hirondellea gigas Halice sp. MT-2017, which are predominant inhabitants in Challenger Deep. Results showed that Tenericutes Proteobacteria were most abundant phyla, occupying more than 50% total across all...
Precise gene expression reflects the molecular response of deep-sea organisms to their harsh living environments. However, changes in environmental factors during lifting samples from deep sea a research vessel can also affect expression. By using transcriptomic approach, we compared profiles onboard fixed with situ limpet Bathyacmaea lactea. Our results revealed that concomitant stress conventional sampling without RNA fixation greatly influenced Various biological activities, such as cell...
Small amphipods (Halice sp. MT-2017) with body length <1 cm were collected from the Challenger Deep (~10,920 m below sea level). The divergence time of their lineage was approximately 109 Mya, making this group ancient compared to others under study. mitochondrial genome Halice shared usual gene components metazoans, comprising 13 protein coding genes (PCGs), 22 transfer RNAs (tRNAs), and 2 ribosomal (rRNAs). arrangement these genes, however, differed greatly that other amphipods. Of 15...
Diffusing fluid at a deep-sea hydrothermal vent creates rapid, acute physico-chemical gradients that correlate strongly with the distribution of fauna. Two alvinocaridid shrimps, Alvinocaris longirostris and Shinkaicaris leurokolos occupy distinct microhabitats around these vents exhibit different thermal preferences. S. inhabits central area closer to active chimney, while A. peripheral area. In this study, we screened candidate genes might be involved in niche separation microhabitat...
Barnacles represent one of the model organisms used for antifouling research, however, knowledge regarding molecular mechanisms underlying barnacle cyprid cementation is relatively scarce. Here, RNA-seq was to obtain transcriptomes cement glands where adhesive generated and remaining carcasses Megabalanus volcano cyprids. Comparative transcriptomic analysis identified 9060 differentially expressed genes, with 4383 upregulated in glands. Four proteins, named Mvcp113k, Mvcp130k, Mvcp52k...
Megabalanus barnacle is one of the model organisms for marine biofouling research. However, further elucidation molecular mechanisms underlying larval settlement has been hindered due to lack genomic information thus far. In present study, cDNA libraries were constructed cyprids, key stage settlement, and adults volcano. After high-throughput sequencing de novo assembly, 42,620 unigenes obtained with a N50 value 1532 bp. These annotated by blasting against NCBI non-redundant (nr),...
No sunlight can reach the hadal trench, but some fishes dwelling there still have apparent eye morphology. However, whether they are capable of sensing light remains unknown. In this study, eyes dominant endemic snailfish Pseudoliparis swirei from Mariana Trench were analyzed using liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS). A total 2088 proteins identified in proteome, most which had at least one hit against public databases and could be mapped to 316 metabolic...
Abstract Settlement-inducing protein complex (SIPC) is a pheromone that triggers conspecific larval settlement in the barnacle Amphibalanus amphitrite . In present study, immunostaining and scanning electron microscopy of SIPC revealed signals frontal horn pores secretions from carapace pores, suggesting might be directly secreted these organs A. cyprids. Further observations showed could contact surfaces while cyprids were “walking”. Immunostaining for on contacted displayed signals. These...
Many deep-sea invertebrates largely depend on chemoautotrophic symbionts for energy and nutrition, some of them have reduced functional digestive tracts. By contrast, mussels a complete system although in their gills play vital roles nutrient supply. This remains can utilise available resources, but the associations among gut microbiomes these remain unknown. Specifically, how microbiome reacts to environmental change is unclear.The meta-pathway analysis showed nutritional metabolic mussel...
ABSTRACT Energy metabolism is a key process in larval settlement of barnacles, but the underlying molecular mechanisms remain ambiguous. Arginine kinase (AK) mainly participates energy invertebrates. So far, its roles barnacles have not been studied. In present study, we raised an antibody against AK from Amphibalanus amphitrite Darwin to characterize process. Among developmental stages, was highly expressed during cypris stage. Along with aging cyprids, level decreased. The immunostaining...
