“…While our own manuscript was in review, new results regarding the symbiosis in A. iwaotakii were published by Thubaut et al [2]. Their results confirm the findings in [1] and constitute a more appropriate reference for our purpose because they are based on clearly identified and vouchered specimens, including microbial 16S rRNA sequences, and important data regarding the biology of A. iwaotakii. We thus updated our electronic supplementary material (data S1) with data published by Thubaut et al [2], including the reference, and we have also linked names of other species for which we used literature data with specimen labels from original publications.…”

“…In 1999, a mussel collected from the Endeavor segment (~60 km from Middle Valley) was assigned to Bathymodiolus based on a mitochondrial cytochrome c oxidase (COI) phylogeny and ultrastructural evidence (McKiness et al 2005). Subsequent phylogenetic analyses of the mitochondrial data using additional taxa and new phylogenetic techniques found a conflicting phylogenetic placement for the JdF mussel (Duperron et al 2009, Kyuno et al 2009); however, further molecular analyses were not possible as tissue was no longer available.…”

Phylogenetic relationships of hydrothermal vent mussels (Bathymodiolinae) and their symbionts

Deep-sea mussels of the subfamily Bathymodiolinae (Bivalvia, Pteriomorphia, Mytilidae) are dominant members of hydrothermal vent communities across the globe and have been found within every known hydrothermal vent biogeographic province. Thus, the apparent rarity of bathymodiolines at vents of the Juan de Fuca Ridge (JdF) is a notable exception. We examined mussels collected from the JdF over a span of 18 yr to clarify the classifications of mussel hosts and their symbiotic bacteria, and the relationships between sparsely distributed individuals. Several specimens, previously classified as Bathymodiolus and Adipicola, were reassigned as Adipicola sp. JdF based on new phylogenetic evidence and previous morphological studies. Adipicola sp. JdF are the most deeply branching members of Adipicola identified to date. Ultrastructural, molecular phylogenetic, and stable carbon isotope analyses indicated that Adipicola sp. JdF mussels harbor bacterial chemoautotrophic symbionts that appear to be extracellular and that are closely related to symbionts of other bathymodioline hosts. This study demonstrates that a sparsely distributed, yet cohesive, population of Adipicola has inhabited JdF vents for at least the past 18 yr. Moreover, the presence of extracellular symbionts in Adipicola sp. JdF at hydrothermal vents stands in contrast to the evolutionary patterns proposed for bathymodiolines in general. Adipicola sp. JdF represents an exception to the trend of bathymodiolines harboring extracellular symbionts living exclusively in shallow marine wood and bone habitats (<1000 m), indicating that bathymodiolines are more flexible with regard to habitat and symbiont characteristics than previously considered.

“…Chemosynthetic-based ecosystems are built around the deep-sea hydrothermal vents and support large microbial communities (Teske, 2009) and symbioses between dominant fauna and intracellular bacteria permitting the existence of animals and microbes under such extreme environments (Duperron et al, 2009).…”

Finding immune gene expression differences induced by marine bacterial pathogens in the Deep-sea hydrothermal vent mussel <i>Bathymodiolus azoricus</i>

Abstract. The deep-sea hydrothermal vent mussel Bathymodiolus azoricus lives in a natural environment characterised by extreme conditions of hydrostatic pressure, temperature, pH, high concentrations of heavy metals, methane and hydrogen sulphide. The deep-sea vent biological systems represent thus the opportunity to study and provide new insights into the basic physiological principles that govern the defense mechanisms in vent animals and to understand how they cope with microbial infections. Hence, the importance of understanding this animal's innate defense mechanisms, by examining its differential immune gene expressions toward different pathogenic agents. In the present study, B. azoricus mussels were infected with single suspensions of marine bacterial pathogens, consisting of Vibrio splendidus, Vibrio alginolyticus, or Vibrio anguillarum, and a pool of these Vibrio bacteria. Flavobacterium suspensions were also used as a non-pathogenic bacterium. Gene expression analyses were carried out using gill samples from infected animals by means of quantitative-Polymerase Chain Reaction aimed at targeting several immune genes. We also performed SDS-PAGE protein analyses from the same gill tissues.We concluded that there are different levels of immune gene expression between the 12 h to 24 h exposure times to various bacterial suspensions. Our results from qPCR demonstrated a general pattern of gene expression, decreasing from 12 h over 24 h post-infection. Among the bacteria tested, Flavobacterium is the bacterium inducing the highest gene expression level in 12 h post-infections animals. The 24 h infected animals revealed, however, greater gene expression levels, using V. splendidus as the infectious agent. The SDS-PAGE analysis also pointed at protein profile differences between 12 h and 24 h, particularly evident for proteins of 18-20 KDa molecular mass, where most dissimilarity was found. Multivariate analyses demonstrated that immune genes, as well as experimental infections, clustered in discrete groups in accordance with the gene expression patterns induced by bacterial pathogens.
