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 ...

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 ...

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

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

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 ...

Revealing novelty from the southwestern Atlantic, Yemanjia gen. nov. and Olokunococcus gen. nov. from the coral cyanobiome of the Abrolhos Bank. [PDF]

J Phycol
Abstract Cyanobacteria comprise over 6000 species and inhabit diverse environments, including marine invertebrates such as sponges and corals. High‐throughput sequencing has indicated an abundance of Cyanobacteria communities in these hosts, yet taxonomic resolution has remained low below the phylum level.

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
