Despite advances in sequencing, lack of standardization makes comparisons across studies challenging and hampers insights into the structure function microbial communities multiple habitats on a planetary scale. Here we present multi-omics analysis diverse set 880 community samples collected for Earth Microbiome Project. We include amplicon (16S, 18S, ITS) shotgun metagenomic sequence data, untargeted metabolomics data (liquid chromatography-tandem mass spectrometry gas chromatography spectrometry). used standardized protocols analytical methods to characterize communities, focusing relationships co-occurrences microbially related metabolites taxa environments, thus allowing us explore diversity at extraordinary In addition reference database metabolomic provide framework incorporating additional studies, enabling expansion existing knowledge form an evolving resource. demonstrate utility this by testing hypothesis that every microbe metabolite is everywhere but environment selects.

Coral‐bleaching responses to climate change across biological scales

Global Change Biology, Journal Year: 2022, Volume and Issue: 28(14), P. 4229 - 4250

Published: April 27, 2022

Abstract The global impacts of climate change are evident in every marine ecosystem. On coral reefs, mass bleaching and mortality have emerged as ubiquitous responses to ocean warming, yet one the greatest challenges this epiphenomenon is linking information across scientific disciplines spatial temporal scales. Here we review some seminal recent coral‐bleaching discoveries from an ecological, physiological, molecular perspective. We also evaluate which data processes can improve predictive models provide a conceptual framework that integrates measurements biological Taking integrative approach scales, using for example hierarchical estimate major coral‐reef processes, will not only rapidly advance science but necessary guide decision‐making conservation efforts. To conserve encourage implementing mesoscale sanctuaries (thousands km 2 ) transcend national boundaries. Such networks protected reefs reef connectivity, through larval dispersal transverse thermal environments, genotypic repositories may become essential units selection environmentally diverse locations. Together, multinational be best chance corals persist change, while humanity struggles reduce emissions greenhouse gases net zero.

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.

Chemical and genomic characterization of a potential probiotic treatment for stony coral tissue loss disease

Communications Biology, Journal Year: 2023, Volume and Issue: 6(1)

Published: April 6, 2023

Abstract Considered one of the most devastating coral disease outbreaks in history, stony tissue loss (SCTLD) is currently spreading throughout Florida’s reefs and greater Caribbean. SCTLD affects at least two dozen different species has been implicated extensive losses cover. Here we show Pseudoalteromonas sp. strain McH1-7 broad-spectrum antibacterial activity against SCTLD-associated bacterial isolates. Chemical analyses indicated produces potential antibacterials, korormicin tetrabromopyrrole, while genomic analysis identified genes potentially encoding an L-amino acid oxidase multiple metalloproteases (pseudoalterins). During laboratory trials, arrested or slowed progression on 68.2% diseased Montastraea cavernosa fragments treated ( n = 22), it prevented transmission by 100% 12). chemically characterized probiotic that effective prophylactic direct treatment for destructive as well a alternative to antibiotic use.

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
