Insights into Symbiont Population Structure among Three Vestimentiferan Tubeworm Host Species at Eastern Pacific Spreading Centers
TLDR
Pangenome composition, genome-wide comparisons of the nucleotide sequences, and pairwise comparisons of 2,313 orthologous genes indicated that “Ca. Endoriftia persephone” symbionts are structured on large geographical scales but also on smaller scales and possibly through host specificity.
Sources of epigenetic variation and their applications in natural populations
TLDR
The microbiome is proposed as an extension of the epigenotype of the host to assess the factors determining the establishment of the community of microorganisms in the applied context of conservation.
Molecular study of bacterial diversity within the trophosome of the vestimentiferan tubeworm Ridgeia piscesae
TLDR
It is concluded that the other adaptive mechanisms must be considered to explain the broad physico-chemical niche occupied by the different growth forms of R. piscesae.
Is the trophosome of Ridgeia piscesae monoclonal?
TLDR
Several lines of molecular evidence for multiple genotypes of very closely related symbionts within the trophosome of the R. piscesae are reported, and compositional and structural variations of CRISPR spacers within aCRISPR array are observed.
Diversity and characterization of bacterial communities of five co‐occurring species at a hydrothermal vent on the Tonga Arc
TLDR
It is confirmed that gill symbiont communities differ among co‐occurring vent invertebrates and indicate that hosts are closely related with their gills symbionts, while campylobacterial Sulfurovum species found across various hosts and habitats are opportunistic associates.
Shining light on a deep-sea bacterial symbiont population structure with CRISPR
TLDR
The high power of CRISPR is shown to resolve the genetic structure of uncultured bacterial populations and represents a step towards making keystone microbial species an integral part of conservation policies for upcoming mining operations on the seafloor.
Differences in cofactor, oxygen and sulfur requirements influence niche adaptation in deep-sea vesicomyid clam symbioses
TLDR
The analyses indicate that the two vesicomyid symbiont groups have a common core genome related to chemosynthetic metabolism, but differ in their potential for nitrate respiration and flexibility to environmental sulfide concentrations, which highlights the role of niche differentiation in creating divergent paths of reductive genome evolution in vertically transmitted symbionts.
Structure and Connectivity of Hydrothermal Vent Communities Along the Mid-Ocean Ridges in the West Indian Ocean: A Review
To date, 13 biologically active hydrothermal vent (HTV) fields have been described on the West Indian Ocean ridges. Knowledge of benthic communities of these vent ecosystems serves as scientific
