Coral holobiont cues prime Endozoicomonas for a symbiotic lifestyle

The ISME Journal, Journal Year: 2022, Volume and Issue: 16(8), P. 1883 - 1895

Published: April 20, 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 novel isolate marisrubri sp. nov. 6c assessed its transcriptomic proteomic response to tissue extracts native host, Red Sea Acropora humilis. We show that stimulated differential expression genes putatively involved symbiosis establishment via modulation host immune by E. 6c, such as for flagellar assembly, ankyrins, ephrins, serpins. Proteome analyses revealed upregulated vitamin B1 B6 biosynthesis glycolytic processes cues. Our results suggest priming a symbiotic lifestyle involves immunity exchange essential metabolites with other members. Consequently, may play an important nutrient cycling therefore contribute health, acclimatization, adaptation.

The coral microbiome: towards an understanding of the molecular mechanisms of coral–microbiota interactions

FEMS Microbiology Reviews, Journal Year: 2023, Volume and Issue: 47(2)

Published: March 1, 2023

Corals live in a complex, multipartite symbiosis with diverse microbes across kingdoms, some of which are implicated vital functions, such as those related to resilience against climate change. However, knowledge gaps and technical challenges limit our understanding the nature functional significance complex symbiotic relationships within corals. Here, we provide an overview complexity coral microbiome focusing on taxonomic diversity functions well-studied cryptic microbes. Mining literature indicate that while corals collectively harbour third all marine bacterial phyla, known symbionts antagonists represent minute fraction this these taxa cluster into select genera, suggesting selective evolutionary mechanisms enabled bacteria gain niche holobiont. Recent advances research aimed at leveraging manipulation increase coral's fitness help mitigate heat stress-related mortality discussed. Then, insights potential through microbiota can communicate modify host responses examined by describing recognition patterns, microbially derived epigenome effector proteins gene regulation. Finally, power omics tools used study highlighted emphasis integrated host-microbiota multiomics framework understand underlying during change-driven dysbiosis.

Building consensus around the assessment and interpretation of Symbiodiniaceae diversity

PeerJ, Journal Year: 2023, Volume and Issue: 11, P. e15023 - e15023

Published: May 2, 2023

Within microeukaryotes, genetic variation and functional sometimes accumulate more quickly than morphological differences. To understand the evolutionary history ecology of such lineages, it is key to examine diversity at multiple levels organization. In dinoflagellate family Symbiodiniaceae, which can form endosymbioses with cnidarians ( e.g ., corals, octocorals, sea anemones, jellyfish), other marine invertebrates e.g. , sponges, molluscs, flatworms), protists foraminifera), molecular data have been used extensively over past three decades describe phenotypes make ecological inferences. Despite advances in Symbiodiniaceae genomics, a lack consensus among researchers respect interpreting has slowed progress field acted as barrier reconciling observations. Here, we identify challenges regarding assessment interpretation across levels: species, populations, communities. We summarize areas agreement highlight techniques approaches that are broadly accepted. where debate remains, unresolved issues discuss technologies help fill knowledge gaps related phenotypic diversity. also ways stimulate progress, particular by fostering inclusive collaborative research community. hope this perspective will inspire accelerate coral reef science serving resource those designing experiments, publishing research, applying for funding their symbiotic partnerships.

Probiotics reshape the coral microbiome in situ without detectable off-target effects in the surrounding environment

Communications Biology, Journal Year: 2024, Volume and Issue: 7(1)

Published: April 9, 2024

Beneficial microorganisms for corals (BMCs), or probiotics, can enhance coral resilience against stressors in laboratory trials. However, the ability of probiotics to restructure microbiome situ is yet be determined. As a first step elucidate this, we inoculated putative probiotic bacteria (pBMCs) on healthy colonies Pocillopora verrucosa Red Sea, three times per week, during 3 months. pBMCs significantly influenced microbiome, while surrounding seawater and sediment remained unchanged. The genera Halomonas, Pseudoalteromonas, Bacillus were enriched probiotic-treated corals. Furthermore, treatment also correlated with an increase other beneficial groups (e.g., Ruegeria Limosilactobacillus), decrease potential pathogens, such as Vibrio. all (treated non-treated) throughout experiment, could not track health improvements protection stress. Our data indicate that healthy, therefore stable, microbiomes restructured situ, although repeated continuous inoculations may required these cases. Further, our study provides supporting evidence that, at studied scale, have no detectable off-target effects near

Inherent differential microbial assemblages and functions associated with corals exhibiting different thermal phenotypes

Science Advances, Journal Year: 2025, Volume and Issue: 11(3)

Published: Jan. 17, 2025

Certain coral individuals exhibit enhanced resistance to thermal bleaching, yet the specific microbial assemblages and their roles in these phenotypes remain unclear. We compared communities of bleaching–resistant (TBR) bleaching–sensitive (TBS) corals using metabarcoding metagenomics. Our multidomain approach revealed stable distinct compositions between phenotypes. Notably, TBR were inherently enriched with eukaryotes, particularly Symbiodiniaceae, linked photosynthesis, biosynthesis antibiotic antitumor compounds glycosylphosphatidylinositol-anchor proteins, crucial for cell wall regulation metabolite exchange. In contrast, TBS dominated by bacterial metabolic genes related nitrogen, amino acid, lipid metabolism. The inherent microbiome differences corals, already observed before stress, point holobiont associated bleaching resistance, offering insights into mechanisms underlying response climate-induced stress.

High-resolution spatial and genomic characterization of coral-associated microbial aggregates in the coral Stylophora pistillata

Science Advances, Journal Year: 2022, Volume and Issue: 8(27)

Published: July 6, 2022

Bacteria commonly form aggregates in a range of coral species [termed coral-associated microbial (CAMAs)], although these structures remain poorly characterized despite extensive efforts studying the microbiome. Here, we comprehensively characterize CAMAs associated with Stylophora pistillata and quantify their cell abundance. Our analysis reveals that multiple Endozoicomonas phylotypes coexist inside single CAMA. Nanoscale secondary ion mass spectrometry imaging revealed cells were enriched phosphorus, elemental compositions different from tissues endosymbiotic Symbiodiniaceae, highlighting role sequestering cycling phosphate between holobiont partners. Consensus metagenome-assembled genomes two dominant confirmed metabolic potential for polyphosphate accumulation along genomic signatures including type VI secretion systems allowing host association. findings provide unprecedented insights into Endozoicomonas-dominated first direct physiological linked evidence biological holobiont.
