Project description:Recent studies have unveiled the deep sea as a rich biosphere, populated by species descended from shallow-water ancestors post-mass extinctions. Research on genomic evolution and microbial symbiosis has shed light on how these species thrive in extreme deep-sea conditions. However, early adaptation stages, particularly the roles of conserved genes and symbiotic microbes, remain inadequately understood. This study examined transcriptomic and microbiome changes in shallow-water mussels Mytilus galloprovincialis exposed to deep-sea conditions at the Site-F cold seep in the South China Sea. Results reveal complex gene expression adjustments in stress response, immune defense, homeostasis, and energy metabolism pathways during adaptation. After 10 days of deep-sea exposure, shallow-water mussels and their microbial communities closely resembled those of native deep-sea mussels, demonstrating host and microbiome convergence in response to adaptive shifts. Notably, methanotrophic bacteria, key symbionts in native deep-sea mussels, emerged as a dominant group in the exposed mussels. Host genes involved in immune recognition and endocytosis correlated significantly with the abundance of these bacteria. Overall, our analyses provide insights into adaptive transcriptional regulation and microbiome dynamics of mussels in deep-sea environments, highlighting the roles of conserved genes and microbial community shifts in adapting to extreme environments.

Project description:Marine microorganisms inhabiting the bathypelagic zone (1000 m - 4000 m) are pivotal to biogeochemical cycling. However, a comprehensive understanding of microbial community structure and their metabolic activities adaptations to the extreme deep-sea conditions remains elusive. In this study, we employed a metaproteomic approach to investigate the protein profiles of microbial communities spanning the surface and bathypelagic layers of the South China Sea (SCS) and performed a comparative analysis with metagenomic data. The metaproteome and metagenome showed low correlation in functional expression but a high correlation at the phylum level. High-abundance genes were more likely to be translated into proteins, with protein over-representation observed in energy conversion and matter transport processes. Short-chain amide porins facilitate substance exchange and maintain cellular homeostasis, enabling Methylococcales to adapt to deep-sea conditions and actively oxidize methane. Flexible energy utilization strategies, such as CO oxidation, enable Propionibacteriales to thrive in deep-sea environments. This study highlights the significance of microbial enzyme resources and offers valuable insights into the adaptations of deep-sea microorganisms, emphasizing their considerable application potential.

Project description:Microbially influenced corrosion (MIC) poses a major threat to metal structures across various industries, resulting in substantial economic losses and environmental risks. As deep-sea exploration expands, understanding MIC under high hydrostatic pressure becomes increasingly critical. Microorganisms in these extreme environments undergo distinct structural and metabolic adaptations to survive and thrive. In this study, we employed a proteomic approach to examine the lifestyle and corrosive potential of two sulfate-reducing bacteria (SRB) species with different pressure optima under simulated depths ranging from the sea surface to 3000 meters. Species-specific corrosion mechanisms and unique proteomic signatures associated with pressure adaptation were identified, correlating with opposing trends in corrosion rates. Our findings emphasize the need to characterize microbial physiology in relation to environmental conditions to better predict corrosion risks in extreme deep-sea settings.

Project description:We designed an experimental setup to investigate the transcriptomic and proteomic responses of the hyperthermophilic archaeon Pyrococcus furiosus to heat and cold shock. P. furiosus is a model organism for studying microbial adaptation to extreme environments, including deep-sea hydrothermal vents with temperature gradients ranging from 1°C to 400°C. We aimed to simulate critical conditions where P. furiosus cannot grow and to examine the immediate response to thermal stress as well as the recovery process.

Project description:The existence of light in various deep-sea environments has been well established. Our previous research found blue light promotes zero-valent sulfur (ZVS) production in Erythrobacter flavus 21-3, a bacterium isolated from the deep-sea cold seep. E. flavus 21-3 can convert thiosulfate to ZVS through a novel thiosulfate oxidation pathway comprising a thiosulfate dehydrogenase (TsdA) and two thiosulfohydrolases (SoxB). Using proteomic analysis, bacterial two-hybrid system and heterologous expression assays, we found that infrared light also promotes zero-valent sulfur (ZVS) production in E. flavus 21-3. The bacteriophytochrome (bphp) Ef2bphp-15570 autophosphorylated and activated GGDEF domain-containing protein D0Y83_RS00450 to produce c-di-GMP. Subsequently, the PilZ protein mPilZ-1753 bound to c-di-GMP and activated downstream sulfur oxidation pathways. During this process, polyphosphate kinase 2 (PPK2) affects the content of c-di-GMP by competing for GTP, thereby together c-di-GMP regulating ZVS production, as well as other metabolic processes in E. flavus 21-3. This study provides a novel insight into a deep-sea non-photosynthetic bacterium which sensing infrared light to regulate sulfur metabolism through a bacteriophytochrome photoreceptor, thus offering new understandings perspectives on microbial utilization of light energy.

Project description:Iron-sulfur minerals such as pyrite are found in many marine benthic habitats. At deep-sea hydrothermal vent sites they occur as massive sulfide chimneys. Hydrothermal chimneys formed by mineral precipitation from reduced vent fluids upon mixing with cold oxygenated sea water. While microorganisms inhabiting actively venting chimneys and utilizing reduced compounds dissolved in the fluids for energy generation are well studied, only little is known about the microorganisms inhabiting inactive sulfide chimneys. We performed a comprehensive meta-proteogenomic analysis combined with radiometric dating to investigate the diversity and function of microbial communities found on inactive sulfide chimneys of different ages from the Manus Basin (SW Pacific). Our study sheds light on potential lifestyles and ecological niches of yet poorly described bacterial clades dominating inactive chimney communities.

Project description:Sulfur metabolism in the deep-sea cold seep has been mentioned to have an important contribution to the biogeochemical cycle of sulfur in previous studies. And sulfate reducing bacteria have also been considered to be a dominant microbial population in the deep-sea cold seep and play a crucial role in this process. However, most of sulfate reducing bacteria from cold seep still cannot be purely cultured under laboratory conditions, therefore the actual sulfur metabolism pathways in sulfate reducing bacteria from the deep-sea cold seep have remained unclear. Here, we isolate and pure culture a typical sulfate reducing bacterium Desulfovibrio marinus CS1 from the sediment sample of the deep-sea cold seep in the South China Sea, which provides a probability to understand the sulfur metabolism in the cold seep.

Project description:Vestimentiferan tubeworms are representative inhabitants of deep-sea chemosynthetic ecosystems. The plume serves as the primary organ in these invertebrates without mouths and guts, facilitating direct metabolic exchange with their surrounding environments. In this study, we present a single-cell transcriptome atlas of Paraescarpia echinospica plume and this study is the initial single-cell transcriptome sequencing for the plume of the deep-sea tubeworm. We annotated six cell clusters including hemocytes, proliferative cells, muscle cells, epithelial cells, nerve1 cells, nerve2 cells and profiled genes involved in immunity and transport. This work will provide a foundation for further studies of tubeworm at the single-cell level.
