Microbiome Stability Is Linked to Acropora Coral Thermotolerance in Northwestern Philippines

Environmental Microbiology, Год журнала: 2025, Номер 27(2)

Опубликована: Янв. 31, 2025

Corals associate with a diverse community of prokaryotic symbionts that provide nutrition, antioxidants and other protective compounds to their host. However, the influence microbes on coral thermotolerance remains understudied. Here, we examined microbial communities associated colonies Acropora cf. tenuis exhibit high or low upon exposure 33°C (heated) relative 29°C (control). Using 16S rRNA sequencing, show structure all A. was similar each at control temperature. Thermotolerant colonies, however, had relatively greater abundance Endozoicomonas, Arcobacter, Bifidobacterium Lactobacillus. At elevated temperature, only thermosensitive showed distinct shift in microbiome, an increase Flavobacteriales, Rhodobacteraceae Vibrio, accompanying marked bleaching response. Functional prediction indicated thermotolerant corals were enriched for genes related metabolism, while microbiomes cell motility antibiotic compound synthesis. These differences may contribute variable performance under thermal stress. Identification taxa correlated provides insights into beneficial bacterial groups could be used microbiome engineering support reef health changing climate.

Evidence for microbially-mediated tradeoffs between growth and defense throughout coral evolution

Animal Microbiome, Год журнала: 2025, Номер 7(1)

Опубликована: Янв. 3, 2025

Abstract Background Evolutionary tradeoffs between life-history strategies are important in animal evolution. Because microbes can influence multiple aspects of host physiology, including growth rate and susceptibility to disease or stress, changes animal-microbial symbioses have the potential mediate tradeoffs. Scleractinian corals provide a biodiverse, data-rich, ecologically-relevant system explore this idea. Results Using comparative approach, we tested if coral microbiomes correlate with across 425 million years evolution by conducting cross-species microbiome survey (the “Global Coral Microbiome Project”) combining results long-term global prevalence trait data. Interpreting these data their phylogenetic context, show that microbial dominance predicts susceptibility, traced dominance-disease association single putatively beneficial symbiont genus, Endozoicomonas. Endozoicomonas relative abundance tissue explained 30% variation 60% 40 genera, while also correlating strongly high rates. Conclusions These demonstrate symbiosis correlates both rate, suggest mediating role. Exploration mechanistic basis for findings will be our understanding how

Unusual Ecofunctional Traits ofEndozoicomonas: A Pan-Genomic Perspective

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2025, Номер unknown

Опубликована: Март 11, 2025

Abstract Background Endozoicomonas is a widely distributed genus of marine bacteria, associated with various organisms, and recognized for its ecological importance in host health, nutrient cycling, disease dynamics. Despite significance, genomic features remain poorly characterized due to limited availability high-quality genome assemblies. Results In this study, we sequenced 5 novel strains re-sequenced 1 known strain improve resolution. By integrating these 6 genomes 31 others that were publicly available, identified distinct, coral-associated clade not by the previous two-clade classification. Pan-genomic analysis revealed significant variation genetic trait distribution among clades. Notably, lacks quorum sensing capabilities, suggesting resistance quenching mechanisms. It also ability synthesize transport vitamin B12, indicating it primary source holobionts. A remarkable feature abundance giant proteins, ranging from 15 65 kbp. We 92 such which clustered into three major groups based on amino acid similarity, each specialized functions, as antimicrobial synthesis, exotoxin production, cell adhesion. Additionally, explored prophages CRISPR-Cas systems. found acquired diverse sources via infection or other types gene transfer. sequences suggest independent evolutionary trajectories both prophage acquisition phylogenetic lineage, implying potential influence geographic environmental pressures. Conclusions This study provides new insights diversity adaptation hosts. Identification features, including deficiencies B12 synthesis sensing, presence prophages, systems, underscores roles These findings open avenues research interactions.

Phototrophic bacteria as potential probiotics for corals

npj Biodiversity, Год журнала: 2025, Номер 4(1)

Опубликована: Апрель 29, 2025

Coral-associated microorganisms provide crucial nutritional, protective, and developmental benefits, yet many functional traits remain unexplored. Phototrophic bacteria may enhance coral nutrition reduce oxidative stress during bleaching via photosynthesis antioxidant production. Despite this potential, their role in the holobiont's energy budget heat resilience is understudied. This review explores potential of phototrophic to health under environmental stress.
