Exaiptasia is a laboratory sea anemone model system for stony corals. Two clonal strains are commonly used, referred to as H2 and CC7, that originate from two genetically distinct lineages and that differ in their Symbiodinium specificity. However, little is known about their other microbial associations. Here, we examined and compared the taxonomic composition of the bacterial assemblages of these two symbiotic Exaiptasia strains, both of which have been cultured in the laboratory long-term… Expand

Microbiome characterization of defensive tissues in the model anemone Exaiptasia diaphana
TLDR
This study provides insight into potential bacterial involvement in cnidarian defense tissues and highlights the need to study bacterial communities in individual compartments within a holobiont. Expand
Microbiota characterization of Exaiptasia diaphana from the Great Barrier Reef
TLDR
The bacterial and Symbiodiniaceae associates of four Great Barrier Reef (GBR)-sourced E. diaphana genotypes established in laboratory aquaria and designated AIMS1–4 are investigated and make an important contribution to the establishment of a GBR-sourced coral model organism. Expand
Short-Term Exposure to Sterile Seawater Reduces Bacterial Community Diversity in the Sea Anemone, Exaiptasia diaphana
The global decline of coral reefs heightens the need to understand how corals may persist under changing environmental conditions. Restructuring of the coral-associated bacterial community, eitherExpand
Metagenomic assessment of body surface bacterial communities of the sea urchin, Tripneustes gratilla.
TLDR
The putative metabolic functions assigned to the bacterial communities showed that heterotrophic bacteria appear to be responsible for tissue lysis of degrading animal matter, suggesting that complex bacterial agents, rather than a specific pathogenic agent, are likely causing this balding disease. Expand
Long-Term Temperature Stress in the Coral Model Aiptasia Supports the “Anna Karenina Principle” for Bacterial Microbiomes
TLDR
Investigating the bacterial communities of different Aiptasia host-symbiont combinations under long-term heat stress in laboratory conditions found a higher number of taxa, and consequently increased α-diversity and β-dispersion, were observed in the microbiomes of heat-stressed individuals across all host strains and experimental batches. Expand
Local Conditions Influence the Prokaryotic Communities Associated With the Mesophotic Black Coral Antipathella subpinnata
TLDR
Ass assessments of black coral-microbe symbioses are provided by investigating the spatial and temporal stability of these associations, and suggesting that this coral holobiont possesses a high degree of microbiome flexibility, which may be a mechanism to acclimate to environmental change. Expand
Corals and Sponges Under the Light of the Holobiont Concept: How Microbiomes Underpin Our Understanding of Marine Ecosystems
In the past 20 years, a new concept has slowly emerged and expanded to various domains of marine biology research: the holobiont. A holobiont describes the consortium formed by a eukaryotic host andExpand
First insight into the viral community of the cnidarian model metaorganism Aiptasia using RNA-Seq data
TLDR
It is found that some viral taxa exhibited significant changes in their relative abundance when Aiptasia engaged in a symbiotic relationship with Symbiodinium, suggesting a role of viruses in the algal endosymbiosis, but the functional significance of this remains to be determined. Expand
Surface Topography, Bacterial Carrying Capacity, and the Prospect of Microbiome Manipulation in the Sea Anemone Coral Model Aiptasia
TLDR
The results shed light on the putative difficulties of transplanting microbiomes between cnidarians in a manner that consistently changes microbial host association at large and provides an avenue to identify bacterial taxa that exhibit broad ability to colonize different hosts as a starting point for cross-species microbiome manipulation. Expand
Temperature transcends partner specificity in the symbiosis establishment of a cnidarian
TLDR
The role of temperature and partner fidelity in the establishment and performance of symbiosis is highlighted and the importance of heterotrophy for symbiotic cnidarians to endure and recover from stress is demonstrated. Expand

Isolation of clonal axenic strains of the symbiotic dinoflagellate Symbiodinium and their growth and host specificity1
TLDR
The Aiptasia‐Symbiodinium association represents an important model system for dissecting aspects of the physiology and cellular and molecular biology of cnidarian‐dinoflagellate mutualism and exploring issues that bear directly on coral bleaching. Expand
Long-term maintenance of species-specific bacterial microbiota in the basal metazoan Hydra
  • S. Fraune, T. Bosch
  • Biology, Medicine
  • Proceedings of the National Academy of Sciences
  • 2007
TLDR
The analysis suggests that the Hydra epithelium actively selects and shapes its microbial community, and strongly indicates distinct selective pressures imposed on and within the epithelia. Expand
Microbiome structure of the fungid coral Ctenactis echinata aligns with environmental differences
TLDR
It is demonstrated that the content and structure of the coral microbiome aligns with environmental differences and denotes habitat adequacy, and availability of a range of coral host habitats might be important for the conservation of distinct microbiome structures and diversity. Expand
Distinct Bacterial Communities Associated with the Coral Model Aiptasia in Aposymbiotic and Symbiotic States with Symbiodinium
TLDR
It is suggested that bacteria play an important role in the symbiosis of Aiptasia with Symbiodinium, a finding that underlines the power of the AiptAsia model system where cnidarian hosts can be analyzed in aposymbiotic and symbiotic states. Expand
Endozoicomonas genomes reveal functional adaptation and plasticity in bacterial strains symbiotically associated with diverse marine hosts
TLDR
Novel Endozoicomonas genomes generated from single cells and metagenomes obtained directly from the corals showed evidence for differential functional specificity and diversification, including genes for the production of amino acids, suggesting that different genotypes play disparate roles and have diversified in concert with their hosts.

Sponge-Associated Bacteria Are Strictly Maintained in Two Closely Related but Geographically Distant Sponge Hosts
TLDR
Comparing the bacterial communities associated with closely related but geographically distant sponge hosts, gives new insight into the intimate relationships between marine sponges and some of their bacterial symbionts. Expand
Molecular Evidence for a Uniform Microbial Community in Sponges from Different Oceans
TLDR
A picture emerges where sponges can be viewed as highly concentrated reservoirs of so far uncultured and elusive marine microorganisms. Expand
Habitat-specific environmental conditions primarily control the microbiomes of the coral Seriatopora hystrix
TLDR
This study suggests that the control of microbial communities associated with the scleractinian coral S. hystrix is driven primarily by external environmental conditions rather than by those directlyassociated with the coral holobiont. Expand
Coral-Associated Bacterial Diversity Is Conserved across Two Deep-Sea Anthothela Species
TLDR
Overall, many of the bacterial associates identified in this study have the potential to contribute to the acquisition and cycling of nutrients within the coral holobiont. Expand
The coral core microbiome identifies rare bacterial taxa as ubiquitous endosymbionts
TLDR
The coral core microbiome is characterized and clear phylogenetic and functional divisions between the micro-scale, niche habitats within the coral host are demonstrated, discovering seven distinct bacterial phylotypes that are universal to the core microbiome of coral species, separated by thousands of kilometres of oceans.
