Significant Changes in Bacterial Communities Associated with Pocillopora Corals Ingestion by Crown-of-Thorns Starfish: An Important Factor Affecting the Coral’s Health

Microorganisms, 2022
Coral ingestion by crown-of-thorns starfish (COTS) is an important cause of coral reef degradation, although the impacts of COTS feeding on coral-associated microbial communities are not well understood.

Defining Coral Bleaching as a Microbial Dysbiosis within the Coral Holobiont [PDF]

Microorganisms, 2020
Coral microbiomes are critical to holobiont health and functioning, but the stability of host–microbial interactions is fragile, easily shifting from eubiosis to dysbiosis. The heat-induced breakdown of the symbiosis between the host and its dinoflagellate algae (that is, “bleaching”), is one of the most devastating outcomes for reef ecosystems.

Genomic signatures suggesting adaptation to ocean acidification in a coral holobiont from volcanic CO2 seeps

Communications Biology, 2023
Ocean acidification, caused by anthropogenic CO2 emissions, is predicted to have major consequences for reef-building corals, jeopardizing the scaffolding of the most biodiverse marine habitats.

Contrasting physiological adaptation strategies to natural environmental change in two Red Sea coral holobionts. [PDF]

ISME Commun
Coral holobionts acquire energy and nutrients from heterotrophic feeding, Symbiodiniaceae symbiosis, and additional metabolic functions (e.g. nitrogen (N) fixation) from associated bacterial communities. Since symbioses often require stable environmental

Mutualistic Interactions between Dinoflagellates and Pigmented Bacteria Mitigate Environmental Stress

Microbiology Spectrum, 2023
Scleractinian corals form symbiotic relationships with a variety of microorganisms, including endosymbiotic dinoflagellates of the family Symbiodiniaceae, and with bacteria, which are collectively termed coral holobionts.

Evidence for phosphonate usage in the coral holobiont [PDF]

The ISME Journal, 2009
Abstract Phosphonates are characterized by a stable carbon–phosphorus bond and commonly occur as lipid conjugates in invertebrate cell membranes. Phosphonoacetate hydrolase encoded by the phnA gene, catalyses the cleavage of phosphonoacetate to acetate and phosphate.

Octocorals in the Gulf of Aqaba exhibit high photosymbiont fidelity

Frontiers in Microbiology, 2022
Symbiotic associations, widespread in terrestrial and marine ecosystems, are of considerable ecological importance. Many tropical coral species are holobionts, formed by the obligate association between a cnidarian host and endosymbiotic dinoflagellates ...

Responses of Symbiodiniaceae Shuffling and Microbial Community Assembly in Thermally Stressed Acropora hyacinthus

Frontiers in Microbiology, 2022
Although the importance of coral holobionts is widely accepted, the relationship between the flexibility of the microbial structure and the coral host is very complicated.

Nitric oxide production rather than oxidative stress and cell death is associated with the onset of coral bleaching in Pocillopora acuta [PDF]

PeerJ, 2022
Elevated seawater temperatures associated with climate change lead to coral bleaching. While the ultimate causes of bleaching are well understood, the proximate physiological mechanisms underlying the bleaching response are not as well defined.
