Sponge-derived matter is assimilated by coral holobionts [PDF]

Communications Biology, 2023
Coral reef biodiversity is maintained by a complex network of nutrient recycling among organisms. Sponges assimilate nutrients produced by other organisms like coral and algae, releasing them as particulate and dissolved matter, but to date, only a ...

Relative abundance of nitrogen cycling microbes in coral holobionts reflects environmental nitrate availability [PDF]

Royal Society Open Science, 2021
Recent research suggests that nitrogen (N) cycling microbes are important for coral holobiont functioning. In particular, coral holobionts may acquire bioavailable N via prokaryotic dinitrogen (N2) fixation or remove excess N via denitrification activity.

Elucidating gene expression adaptation of phylogenetically divergent coral holobionts under heat stress [PDF]

Nature Communications, 2021
As corals struggle to survive under climate change, it is crucial to know whether they can withstand increasing seawater temperatures. Using a controlled thermal stress experiment across three divergent coral holobionts, this study examines ...

Changes in the diversity and functionality of viruses that can bleach healthy coral [PDF]

mSphere
Coral microbiomes play a crucial role in maintaining the health and functionality of holobionts. Disruption in the equilibrium of holobionts, including bacteria, fungi, and archaea, can result in the bleaching of coral. However, little is known about the

The Host Coral Bleaching Response Viewed Through the Lens of Multi-Omics: Multi-Omics Provides the Tools to Understand the Complex Molecular Basis of Coral Bleaching, Which Can Aid Conservation Efforts. [PDF]

Bioessays
Coral bleaching is driven by multiple inputs, with heat stress and/or high irradiance being most important. The bleaching response is multifactorial with host animal species/strain and algal symbiont genotypes being critical features. Omics readout of heat stress responses includes gene expression, proteomics, metabolite, and SNP data with transcript ...

Extracellular enzymatic activities of octocorals and scleractinian corals under environmental stress [PDF]

Scientific Reports
Extracellular enzymes, released by coral holobionts (coral host, symbiotic dinoflagellates and associated microorganisms) are involved in nutrient cycling and can serve as diagnostic indicators of coral health and reef ecosystem functionality.

Coral microbiome in estuary coral community of Pearl River Estuary: insights into variation in coral holobiont adaptability to low-salinity conditions [PDF]

BMC Microbiology
Background Low salinity is a crucial environmental stressor that affects estuarine coral ecosystems considerably. However, few studies have focused on the effects of low-salinity conditions on coral-associated microorganisms and the adaptability of coral

Heatwave-driven persistent microbes threaten the resilience of Mediterranean coral holobionts [PDF]

Environmental Microbiome
Background The climate crisis poses a serious threat to octocorals in the Mediterranean Sea as marine heatwaves (MHWs) not only impair coral metabolism but also disrupt the complex symbiosis between the coral host and its microbiome. Since octocorals are

Positive Interactions Under Ocean Warming and Acidification: Crustose Coralline Algae Holobionts Enhance Gorgonian Larval Settlement Under Climate Change. [PDF]

Environ Microbiol
Crustose coralline algae (CCA) are key for the settlement of the larvae of the Mediterranean white gorgonian, Eunicella singularis, especially after treatment under future climate change conditions. CCA also influence larval microbiome development. (A) Enhanced larval settlement is driven by bacterial breakdown and utilisation of CCA polysaccharides ...

Unveiling the Microeukaryotic Landscape of the Red Coral Corallium rubrum Across the Northwestern Mediterranean Sea. [PDF]

Environ Microbiol Rep
This study demonstrates that the eukaryome of the Mediterranean octocoral Corallium rubrum exhibits high variability, and the dominance of certain taxa is influenced by spatiotemporal environmental factors. Despite this, core microeukaryotic families, such as Licnophoridae and Dino‐Group I Clade 1, were consistently present, suggesting key roles in the
