Harnessing the Power of Model Organisms To Unravel Microbial Functions in the Coral Holobiont. [PDF]

Microbiol Mol Biol Rev, 2022
Stony corals build the framework of coral reefs, ecosystems of immense ecological and economic importance. The existence of these ecosystems is threatened by climate change and other anthropogenic stressors that manifest in microbial dysbiosis such as ...

Divergent responses of the coral holobiont to deoxygenation and prior environmental stress

Frontiers in Marine Science, 2023
Ocean deoxygenation is intensifying globally due to human activities – and is emerging as a grave threat to coral reef ecosystems where it can cause coral bleaching and mass mortality.

Holo-2bRAD: A Hologenomic Method for High-Resolution Analysis of Coral Microbiomes During Bleaching [PDF]

Microorganisms
Coral reefs are biodiversity hotspots increasingly threatened by climate-induced bleaching, yet profiling the coral holobiont—the host and its associated microbiota—remains technically challenging due to high host-DNA contamination (often >95%) and the ...

Heat stress reduces the contribution of diazotrophs to coral holobiont nitrogen cycling. [PDF]

ISME J, 2022
Efficient nutrient cycling in the coral-algal symbiosis requires constant but limited nitrogen availability. Coral-associated diazotrophs, i.e., prokaryotes capable of fixing dinitrogen, may thus support productivity in a stable coral-algal symbiosis but

Heterotrophic feeding and symbiotic state shape the chemical microenvironment, microbiome composition, and activity in the coral gastrovascular cavity [PDF]

Applied and Environmental Microbiology
Coral gastrovascular cavities (GVCs) host diverse microorganisms and, as semi-closed compartments, are characterized by elevated nutrient concentrations and pronounced diel fluctuations in oxygen (O2) and pH.

Diel transcriptional responses of coral-Symbiodiniaceae holobiont to elevated temperature

Communications Biology
Coral exhibits diel rhythms in behavior and gene transcription. However, the influence of elevated temperature, a key factor causing coral bleaching, on these rhythms remains poorly understood.

Peeling back the layers of coral holobiont multi-omics data. [PDF]

iScience, 2023
The integration of multiple 'omics' datasets is a promising avenue for answering many important and challenging questions in biology, particularly those relating to complex ecological systems. Although multi-omics was developed using data from model organisms with significant prior knowledge and resources, its application to non-model organisms, such ...

Localization and symbiotic status of probiotics in the coral holobiont. [PDF]

mSystems
ABSTRACT Corals establish symbiotic relationships with microorganisms, especially endosymbiotic photosynthetic algae. Although other microbes have been commonly detected in coral tissues, their identity and beneficial functions for their host are unclear. Here, we confirm the beneficial outcomes of the

The coral Oculina patagonica holobiont and its response to confinement, temperature, and Vibrio infections

Microbiome
Background Extensive research on the diversity and functional roles of the microorganisms associated with reef-building corals has been promoted as a consequence of the rapid global decline of coral reefs attributed to climate change.
