Annual Review of Microbiology, Journal Year: 2016, Volume and Issue: 70(1), P. 317 - 340

Published: Aug. 2, 2016

Corals are fundamental ecosystem engineers, creating large, intricate reefs that support diverse and abundant marine life. At the core of a healthy coral animal is dynamic relationship with microorganisms, including mutually beneficial symbiosis photosynthetic dinoflagellates (Symbiodinium spp.) enduring partnerships an array bacterial, archaeal, fungal, protistan, viral associates, collectively termed holobiont. The combined genomes this holobiont form hologenome, genomic interactions within hologenome ultimately define phenotype. Here we integrate contemporary scientific knowledge regarding ecological, host-specific, environmental forces shaping diversity, specificity, distribution microbial symbionts holobiont, explore physiological pathways contribute to fitness, describe potential mechanisms for homeostasis. Understanding role microbiome in resilience, acclimation, adaptation new frontier reef science will require large-scale collaborative research efforts.

The coral core microbiome identifies rare bacterial taxa as ubiquitous endosymbionts

The ISME Journal, Journal Year: 2015, Volume and Issue: 9(10), P. 2261 - 2274

Published: April 17, 2015

Abstract Despite being one of the simplest metazoans, corals harbor some most highly diverse and abundant microbial communities. Differentiating core, symbiotic bacteria from this host-associated consortium is essential for characterizing functional contributions but has not been possible yet. Here we characterize coral core microbiome demonstrate clear phylogenetic divisions between micro-scale, niche habitats within host. In doing so, discover seven distinct bacterial phylotypes that are universal to species, separated by thousands kilometres oceans. The two co-localized specifically with corals’ endosymbiotic algae symbiont-containing host cells. These symbioses likely facilitate success dinoflagellate endosymbiosis in environmental regimes.

Coral-associated bacteria demonstrate phylosymbiosis and cophylogeny

Nature Communications, Journal Year: 2018, Volume and Issue: 9(1)

Published: Nov. 16, 2018

Scleractinian corals' microbial symbionts influence host health, yet how coral microbiomes assembled over evolution is not well understood. We survey bacterial and archaeal communities in phylogenetically diverse Australian corals representing more than 425 million years of diversification. show that are anatomically compartmentalized both modern ecology evolutionary assembly. Coral mucus, tissue, skeleton differ community composition, richness, response to vs. environmental drivers. also find evidence coral-microbe phylosymbiosis, which microbiome composition richness reflect phylogeny. Surprisingly, the represents most biodiverse microbiome, shows strongest phylosymbiosis. Interactions between phylogeny significantly abundance four groups bacteria-including Endozoicomonas-like bacteria, divide into host-generalist host-specific subclades. Together these results trace symbiosis across anatomy during a basal animal lineage.

The microbiome of coral surface mucus has a key role in mediating holobiont health and survival upon disturbance

The ISME Journal, Journal Year: 2016, Volume and Issue: 10(9), P. 2280 - 2292

Published: March 8, 2016

Microbes are well-recognized members of the coral holobiont. However, little is known about short-term dynamics mucus-associated microbial communities under natural conditions and after disturbances, how these relate to host's health. Here we examined variability prokaryotic (based on 16S ribosomal RNA gene amplicon sequencing) associating with surface mucus layer (SML) Porites astreoides, a species exhibiting cyclical aging shedding. Shifts in community composition during led prevalence opportunistic potentially pathogenic bacteria (Verrucomicrobiaceae Vibrionaceae) aged twofold increase abundance. After release sheets, reverted its original state, dominated by Endozoicimonaceae Oxalobacteraceae. Furthermore, followed fate holobiont upon depletion microbiome through antibiotics treatment. re-introduction reef, healthy-looking microbe-depleted corals started clear signs bleaching necrosis. Recovery versus mortality P. astreoides was related degree change abundance distribution microbiome. We conclude that inhabiting SML contributes health shedding has key role dynamics.

Microbes in the coral holobiont: partners through evolution, development, and ecological interactions

In the last two decades, genetic and genomic studies have revealed astonishing diversity ubiquity of microorganisms. Emergence expansion human microbiome project has reshaped our thinking about how microbes control host health – not only as pathogens, but also symbionts. coral reef environments, scientists begun to examine role that microorganisms play in life history. Herein we review current literature on coral-microbe interactions within context their evolution, development, ecology. We ask following questions, first posed by McFall-Ngai et al., 2013 animal with specific attention coral-microbial may be affected under future environmental conditions: 1) How do corals affect each other's genomes? 2) does development depend microbial partners? 3) is homeostasis maintained between symbionts? 4) can ecological approaches deepen understanding multiple levels interactions? Elucidating structure function holobiont essential for maintain acclimate changing conditions.

The importance of associations between microorganisms and their invertebrate hosts is becoming increasingly apparent. An emerging field, driven by the necessity to understand microbial relationships that both maximize coral health cause disease, study coral–bacteria interactions. In this article, we review our current understanding diversity, specificity, development, functions coral-associated bacteria. We also summarize what known regarding role microbiota in disease coral. conduct a meta-analysis determine whether presence unique taxa correlates with state (i.e. healthy, diseased or bleached), as well reef habitats harbor clusters distinct taxa. find healthy bleached corals similar dominant taxa, although had higher proportions Vibrio Acidobacteria. Diseased generally more Rhodobacter, Clostridia, Cyanobacteria sequences, fewer Oceanospirillum sequences. caution, however, while 16S rRNA useful for species identification, it poor predictor habitat lifestyle, care should be taken interpretation surveys identify potential pathogens amongst complex coral–microbial assemblages. Finally, highlight evidence coral–bacterial assemblages could sensitive effects climatic change. suggest relationship bacterial associates represents valuable model can applied broader discipline invertebrate–microbial
