Transmission of obligate bacterial symbionts between generations is vital for the survival of the host. Although the larvae of certain hydrothermal vent tubeworms (Vestimentifera, Siboglinidae) are symbiont-free and possess a transient digestive system, these structures are lost during development, resulting in adult animals that are nutritionally dependent on their bacterial symbionts. Thus, each generation of tubeworms must be newly colonized with its specific symbiont. Here we present a… 
Endosymbionts escape dead hydrothermal vent tubeworms to enrich the free-living population
It is experimentally shown that symbionts rapidly escape their hosts upon death and recruit to surfaces where they proliferate, suggesting that release of large numbers of Symbionts may ensure effective dispersal to new sites followed by active larval colonization.
Genetics and Evolution of Deep-Sea Chemosynthetic Bacteria and Their Invertebrate Hosts
The prevalence of horizontal transmission systems in chemosynthetic environments suggests that the symbionts must have escape strategies that allow them to ­re-inoculate the ambient environment and contribute to their overall fitness.
Becoming symbiotic – the symbiont acquisition and the early development of bathymodiolin mussels
Symbiotic associations between animals and microorganisms are widespread and have a profound impact on the ecology, behaviour, physiology, and evolution of the host. Research on deep-sea mussels of
Previously unrecognized stages of species‐specific colonization in the mutualism between Xenorhabdus bacteria and Steinernema nematodes
It is shown that bacteria colonize the anterior intestinal cells of other nematode developmental stages in a species‐specific manner, and it is demonstrated that bacterial SR1 genes aid in colonizing nematodes epithelial surfaces.
Evolution and Maintenance of Mutualism between Tubeworms and Sulfur-Oxidizing Bacteria
The model reveals that mutualism can persist only when the host mortality rate is within an intermediate range and the generality of this evolutionary fragility in obligate mutualistic systems as well as the contrasting evolutionary robustness in host-parasite systems are discussed.
Lateral symbiont acquisition in a maternally transmitted chemosynthetic clam endosymbiosis.
Using likelihood and Bayesian model discrimination methods, the strict maternal cotransmission hypothesis is rejected by showing a significant decoupling of symbiont and host mitochondrial (COI and mt16S genes) phylogenies.
Contribution of Maternal and Paternal Transmission to Bacterial Colonization in Nematostella vectensis
This is the first study investigating bacteria transmission in N. vectensis and shed light on the consistent yet distinct maternal and paternal transfer of bacterial symbionts along the different life stages and generations of an aquatic invertebrate.
Endosymbiont genomes yield clues of tubeworm success
The comparative genomic results help elucidate potential mechanisms used to allow chemosynthetically dependent holobionts adapt to, and evolve in, different environments and find that the ability to use hydrogen, as an additional energy source, is potentially more widespread than previously recognized.
Coming together—symbiont acquisition and early development in deep-sea bathymodioline mussels
Within the Mytilidae, this morphological change appears to be specific to Bathymodiolus and Gigantidas, and is probably linked to the decrease in the importance of filter feeding when these mussels switch to gaining their nutrition largely from their symbionts.
Forever competent: deep-sea bivalves are colonized by their chemosynthetic symbionts throughout their lifetime.
Symbiotic bivalves at hydrothermal vents and cold seeps host chemosynthetic bacteria intracellularly in gill cells, indicating that colonization is shaped by the developmental stage of host cells and that gill colonization is a continuous process throughout the host's lifetime.


Molecular phylogenetics of bacterial endosymbionts and their vestimentiferan hosts.
Vestimentiferan tube worms from deep-sea hydrothermal vents and cold-water seeps rely entirely on sulfur-oxidizing bacterial endosymbionts for nutriment. We examined host-symbiont co-evolution by
Ultrastructural reinvestigation of the trophosome in adults of Riftia pachyptila (Annelida, Siboglinidae)
A mesodermal rather than endodermal origin is hypothesized for the trophosome of adults of Riftia pachyptila and its constitute bacteriocytes, which act as stem cells for a proliferating tissue produced in the center and ultimately degraded at the periphery of each lobule.
Larval development and the formation of the gut of Siboglinum poseidoni Flügel & Langhof (Pogonophora, Perviata). Evidence of protostomian affinity
Larvae of Siboglinum poseidoni were reared in the laboratory and a small tentacular bud develops about 6 weeks after recovery from the central Skagerrak, revealing a ciliated opening and tract in this transient digestive tract.
Modeling the Mutualistic Interactions between Tubeworms and Microbial Consortia
A diagenetic model in which tubeworm aggregation persistence is achieved through augmentation of the supply of sulfate to hydrocarbon seep sediments, expanding the concept of the potential benefits derived from complex interspecific relationships, in this case involving members of all three domains of life.
Characterization of chemoautotrophic bacterial symbionts in a gutless marine worm Oligochaeta, Annelida) by phylogenetic 16S rRNA sequence analysis and in situ hybridization
In phylogenetic trees inferred by both distance and parsimony methods, the oligochaete symbiont is peripherally associated with one of two clusters of chemoautotrophic symbionts that belong to the gamma subdivision of the Proteobacteria.
Genetic Variation among Endosymbionts of Widely Distributed Vestimentiferan Tubeworms
A DNA fingerprinting technique was used, repetitive-extragenic-palindrome PCR (REP-PCR), to reveal differences in the distribution of repetitive sequences in the genomes of the bacterial endosymbionts.
Pogonophora (Annelida): form and function
Pogonophora, also known as Siboglinidae, are tube-dwelling marine annelids. They rely on endosymbiotic chemoautotrophic bacteria for nutrition and their anatomy and physiology are adapted to their

The early development of vestimentiferans from cold seeps in the Gulf of Mexico is described and the implications of the findings for dispersal potential and phylogeny are discussed.
Identification and localization of bacterial endosymbionts in hydrothermal vent taxa with symbiont-specific polymerase chain reaction amplification and in situ hybridization techniques.
Testing of group-specific hybridization probes complementary to 16S ribosomal RNAs for symbionts in eggs and ovaries indicates that transovarial symbiont transmission in the vestimentiferans does not take place and that symbionT acquisition is probably a post-spawning event.
