Adaptation to deep-sea chemosynthetic environments as revealed by mussel genomes
The genomes of a deep-sea vent/seep mussel and a shallow-water mussel are reported, revealing presumed genetic adaptation of theDeep-sea mussel to the presence of its chemoautotrophic endosymbionts and wider insights into the mechanisms of symbiosis in other organisms such as deep- sea tubeworms and giant clams are given.

Genomic, transcriptomic, and proteomic insights into the symbiosis of deep-sea tubeworm holobionts
The results reveal the interdependence of the tubeworm holobiont through mutual nutrient supply, a pathogen-type regulatory mechanism, and host-symbiont cooperation in energy utilization and nutrient production, which is a key adaptation allowing the Tubeworm to thrive in deep-sea chemosynthetic environments.

Molecular analyses indicated that the cytochrome oxidase c subunit I gene and 16S RNA gene of Marphysa hongkongensa diverged from the corresponding sequence of the closest related species of MarPhysa in GenBank by 19.5% and 12.1%, respectively.
Genomic Signatures Supporting the Symbiosis and Formation of Chitinous Tube in the Deep-Sea Tubeworm Paraescarpia echinospica
The chromosome-level genome of the vestimentiferan tubeworm Paraescarpia echinospica is reported, finding that the genome has been remodelled to facilitate symbiosis through the expansion of gene families related to substrate transfer and innate immunity, suppression of apoptosis, regulation of lysosomal digestion and protection against oxidative stress.
