Coral holobionts and biotechnology: from Blue Economy to coral reef conservation

Current Opinion in Biotechnology, 2022
Corals are of ecological and economic importance, providing habitat for species and contributing to coastal protection, fisheries, and tourism. Their biotechnological potential is also increasingly recognized. Particularly, the production of pharmaceutically interesting compounds by corals and their microbial associates stimulated natural product-based

Generating viral metagenomes from the coral holobiont [PDF]

Frontiers in Microbiology, 2014
Reef-building corals comprise multipartite symbioses where the cnidarian animal is host to an array of eukaryotic and prokaryotic organisms, and the viruses that infect them. These viruses are critical elements of the coral holobiont, serving not only as agents of mortality, but also as potential vectors for lateral gene flow, and as elements encoding ...

Presence of algal symbionts affects denitrifying bacterial communities in the sea anemone Aiptasia coral model

ISME Communications, 2022
The coral-algal symbiosis is maintained by a constant and limited nitrogen availability in the holobiont. Denitrifiers, i.e., prokaryotes reducing nitrate/nitrite to dinitrogen, could contribute to maintaining the nitrogen limitation in the coral ...

Fungal Host Affects Photosynthesis in a Lichen Holobiont

Journal of Fungi, 2022
Corals and lichens are iconic examples of photosynthetic holobionts, i.e., ecological and evolutionary units resulting from the tightly integrated association of algae and prokaryotic microbiota with animal or fungal hosts, respectively.

The hologenome theory disregards the coral holobiont [PDF]

Nature Reviews Microbiology, 2007
The ‘hologenome theory of evolution’, proposed by Rosenberg and colleagues1, suggests that reef corals, and by extrapolation other multicellular organisms, adapt to environmental stress by alterations in their resident microbial communities. Although this is an interesting idea, we strongly disagree with aspects of this theory, specifically those ...

Organic Carbon and Nitrogen Isoscapes of Reef Corals and Algal Symbionts: Relative Influences of Environmental Gradients and Heterotrophy

Microorganisms, 2020
The elemental (C/N) and stable isotopic (δ13C, δ15N) compositions and compound-specific δ15N values of amino acids (δ15NAA) were evaluated for coral holobionts as diagnostic tools to detect spatiotemporal environmental heterogeneity and its effects on ...

Nitrogen Fixation Aligns with nifH Abundance and Expression in Two Coral Trophic Functional Groups

Frontiers in Microbiology, 2017
Microbial nitrogen fixation (diazotrophy) is a functional trait widely associated with tropical reef-building (scleractinian) corals. While the integral role of nitrogen fixation in coral nutrient dynamics is recognized, its ecological significance ...

Coral holobiont cues prime Endozoicomonas for a symbiotic lifestyle

The ISME Journal, 2022
Abstract Endozoicomonas are prevalent, abundant bacterial associates of marine animals, including corals. Their role in holobiont health and functioning, however, remains poorly understood. To identify potential interactions within the coral holobiont, we characterized the novel isolate Endozoicomonas marisrubri sp. nov.

First insight into the viral community of the cnidarian model metaorganism Aiptasia using RNA-Seq data [PDF]

PeerJ, 2018
Current research posits that all multicellular organisms live in symbioses with associated microorganisms and form so-called metaorganisms or holobionts.

Nitrogen cycling in corals: the key to understanding holobiont functioning? [PDF]

Trends in Microbiology, 2015
Corals are animals that form close mutualistic associations with endosymbiotic photosynthetic algae of the genus Symbiodinium. Together they provide the calcium carbonate framework of coral reef ecosystems. The importance of the microbiome (i.e., bacteria, archaea, fungi, and viruses) to holobiont functioning has only recently been recognized.
