Extracellular and Mixotrophic Symbiosis in the Whale-Fall Mussel Adipicola Pacifica: a Trend in Evolution from Extra- to Intracellular Symbiosis

Such symbiotic associations have been well characterized in mussels collected from vents, seeps and sunken wood but in only a few from whale falls. Methodology/Principal Finding: Here we report symbioses in the gill tissues of two mussels, Adipicola crypta and Adipicola pacifica, collected from whale-falls on the continental shelf in the northwestern Pacific. The molecular, morphological and stable isotopic characteristics of bacterial symbionts were analyzed. A single phylotype of thioautotrophic bacteria was found in A. crypta gill tissue and two distinct phylotypes of bacteria (referred to as Symbiont A and Symbiont C) in A. pacifica. Symbiont A and the A. crypta symbiont were affiliated with thioautotrophic symbionts of bathymodiolin mussels from deep-sea reducing environments, while Symbiont C was closely related to free-living heterotrophic bacteria. -

Mussels of the subfamily Bathymodiolinae from vents and seeps belonged to 3 groups and mytilid relatives from sunken wood and whale carcasses assumed the outgroup positions to bathymodioline mussels. Shallow water mytilid mussels were positioned more distantly relative to the vent/seep mussels, indicating an evolutionary transition from shallow to deep sea via sunken wood and whale carcasses. Bathymodiolus platifrons is distributed in the seeps and vents, which are approximately 1500 km away. There was no significant genetic differentiation between the populations. There existed high gene flow between B. septemdierum and B. -

ODivision of Marine Science, Harbor Branch Oceanographic Institution, 5600 US 1 N, Fort Pierce, FL 34946, USA Reproductive cycles are determined from samples taken at regular intervals over a period of time related to the assumed periodicity of the breeding cycle. Fiscal, ship time and sampling constraints have made this almost impossible at deep-sea vents and seeps, but there is an accumulating mass of data that cast light on these processes. It is becoming apparent that most reproductive processes are phylogeneti- cally conservative, even in extreme vent and seep habitats. Reproductive patterns of species occurring at vents and seeps are not dissimilar to those of species from the same phyla found in non-chemosynthetic environments. The demographic structure of most vent and seep animals is undescribed and the maximum ages and growth rates are not known. We know little about how the gametogenic cycle is initiated, though there is a growing body of data on the size at ¢rst reproduction. -
Genomics and Transcriptomics of the Green Mussel Explain the Durability
www.nature.com/scientificreports OPEN Genomics and transcriptomics of the green mussel explain the durability of its byssus Koji Inoue1*, Yuki Yoshioka1,2, Hiroyuki Tanaka3, Azusa Kinjo1, Mieko Sassa1,2, Ikuo Ueda4,5, Chuya Shinzato1, Atsushi Toyoda6 & Takehiko Itoh3 Mussels, which occupy important positions in marine ecosystems, attach tightly to underwater substrates using a proteinaceous holdfast known as the byssus, which is tough, durable, and resistant to enzymatic degradation. Although various byssal proteins have been identifed, the mechanisms by which it achieves such durability are unknown. Here we report comprehensive identifcation of genes involved in byssus formation through whole-genome and foot-specifc transcriptomic analyses of the green mussel, Perna viridis. Interestingly, proteins encoded by highly expressed genes include proteinase inhibitors and defense proteins, including lysozyme and lectins, in addition to structural proteins and protein modifcation enzymes that probably catalyze polymerization and insolubilization. This assemblage of structural and protective molecules constitutes a multi-pronged strategy to render the byssus highly resistant to environmental insults. Mussels of the bivalve family Mytilidae occur in a variety of environments from freshwater to deep-sea. Te family incudes ecologically important taxa such as coastal species of the genera Mytilus and Perna, the freshwa- ter mussel, Limnoperna fortuneri, and deep-sea species of the genus Bathymodiolus, which constitute keystone species in their respective ecosystems 1. One of the most important characteristics of mussels is their capacity to attach to underwater substrates using a structure known as the byssus, a proteinous holdfast consisting of threads and adhesive plaques (Fig. 1)2. Using the byssus, mussels ofen form dense clusters called “mussel beds.” Te piled-up structure of mussel beds enables mussels to support large biomass per unit area, and also creates habitat for other species in these communities 3,4. -
Vent Fauna in the Mariana Trough 25 Shigeaki Kojima and Hiromi Watanabe
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Springer - Publisher Connector Vent Fauna in the Mariana Trough 25 Shigeaki Kojima and Hiromi Watanabe Abstract The Mariana Trough is a back-arc basin in the Northwestern Pacific. To date, active hydrothermal vent fields associated with the back-arc spreading center have been reported from the central to the southernmost region of the basin. In spite of a large variation of water depth, no clear segregation of vent faunas has been recognized among vent fields in the Mariana Trough and a large snail Alviniconcha hessleri dominates chemosynthesis- based communities in most fields. Although the Mariana Trough approaches the Mariana Arc at both northern and southern ends, the fauna at back-arc vents within the trough appears to differ from arc vents. In addition, a distinct chemosynthesis-based community was recently discovered in a methane seep site on the landward slope of the Mariana Trench. On the other hand, some hydrothermal vent fields in the Okinawa Trough backarc basin and the Izu-Ogasawara Arc share some faunal groups with the Mariana Trough. The Mariana Trough is a very interesting area from the zoogeographical point of view.

Since these environments are seemingly highly different, it is likely that vent and seep populations must be genetically differentiated by adapting to their respective environments. In order to elucidate dispersal ability and envi- ronmental adaptability of deep-sea mussels, we determined mitochondrial ND4 sequences of Bathymodiolus platifrons and B. japonicus obtained from seeps in the Sagami Bay and vents in the Okinawa Trough. Among more than 20 spe- cies of deep-sea mussels, only three species in the Japanese waters including the above species can inhabit both vents and seeps. We examined phylogenetic relationships, genetic divergences (Fst), gene flow (Nm), and genetic population structures to compare the seep and vent populations. Our results showed no genetic differentiation and extensive gene flow between the seep and vent populations, indicating high dispersal ability of the two species, which favors coloniza- tion in patchy and ephemeral habitats. -

Dead Mussels As Food-Stepping Stone Habitats for Deep-Sea Hydrothermal Fauna
Dead mussels as food-stepping stone habitats for deep-sea hydrothermal fauna. Fergus De Faoite (6456340) Master’s Thesis A collaborative project between Utrecht University (UU) and the Royal Netherlands Institute for Sea Research (NIOZ). First Supervisor: Dr. Sabine Gollner (NIOZ) Second Supervisor: Dr. Jack Middelburg (UU) Abstract Hydrothermal vents are patchy ephemeral habitats which are hotspots of productivity in the deep sea. Vent endemic fauna may require intermediate stepping stone habitats to travel from vent to vent with these stepping stones typically comprising of decaying organic matter. Dead Bathymodiolus and Mytilus mussels were placed in ~2200 meters water depth at approximately 4 km distance from the Rainbow Vent Field for one year in order to measure the propensity for vent fauna to use dead mussels as stepping stone habitats. The vent endemic Dirivultidae copepods, Bathymodiolus mussels and generalist Hesionidae and Capillidae polychaetes settled among the mussels. Species richness and evenness was very low among the meiofauna with generalist Tisbe copepods accounting for almost all of the copepods. Macrofaunal samples were much richer and more even in comparison. The meat from the vent endemic Bathymodiolus mussels was consumed after one year while there was still some meat and a sulphurous smell present in the shallow water Mytilus mussels, indicating that decomposition was still taking place. This study indicates that dead mussels could act as a stepping stone habitat for some symbiotic and non-symbiotic vent fauna as such animals were found in the samples. Juvenile Bathymodiolus mussels settled among the dead mussels indicating that conditions were suitable for settlement for symbiotic fauna.
