Endosymbiosis with chemosynthetic bacteria has enabled many deep-sea invertebrates to thrive at hydrothermal vents and cold seeps, but most previous studies on this mutualism have focused on the bacteria only. Vesicomyid clams dominate global deep-sea chemosynthesis-based ecosystems. They differ from most deep-sea symbiotic animals in passing their symbionts from parent to offspring, enabling intricate co-evolution between the host and the symbiont. Here, we sequenced the genomes of the clam Archivesica marissinica (Bivalvia: Vesicomyidae) and its bacterial symbiont to understand the genomic/metabolic integration behind this symbiosis. At 1.52 gigabases, the clam genome encodes 28 genes horizontally transferred from bacteria, a large number of pseudogenes and transposable elements whose massive expansion corresponded to the timing of the rise and subsequent divergence of symbiont-bearing vesicomyids. The genome exhibits gene family expansion in cellular processes that likely facilitate chemoautotrophy, including gas delivery to support energy and carbon production, metabolite exchange with the symbiont, and regulation of the bacteriocyte population. Contraction in cellulase genes is likely adaptive to the shift from phytoplankton-derived to bacteria-based food. It also shows contraction in bacterial recognition gene familie, indicative of suppressed immune response to the endosymbiont. The gammaproteobacterium endosymbiont has a reduced genome of 1.03 megabases but retains complete pathways for sulfur oxidation, carbon fixation, and biosynthesis of 20 common amino acids, indicating the host’s high dependence on the symbiont for nutrition. Overall, the host-symbiont genomes show not only tight metabolic complementarity, but also distinct signatures of co-evolution allowing the vesicomyids to thrive in chemosynthesis-based ecosystems.

“…Metal amide-hydride materials have been extensively investigated in recent years for use in energy storage applications and specifically for storage applications in hydrogen technology (e.g., LiNH 2 -LiH, − Mg(NH 2 ) 2 -2LiH, − Mg(NH 2 ) 2 -KH, and Mg(NH 2 ) 2 -RbH)) and as solid electrolytes − for all solid-state batteries. In hydrogen storage applications, amide-hydride systems prove promising candidates especially due to their high hydrogen storage capacity and tunable thermodynamics, which allows hydrogen desorption/absorption to occur at temperatures below 150 °C .…”

Mixed solid solutions have played an important role in improving the kinetics and performance of hydrogen storage materials, as reported for the Li−Mg−N−H, K−Mg−N−H, and Rb−Mg−N−H systems. Besides, the formation of a homogeneous solid solution, mostly due to partial ionic substitution, is known to be an effective approach to improve the ionic conductivity of a material, which is an important property in electrochemical applications. We have reported a series of solid solutions based on mixed amide-hydride materials of the Group 1 elements, e.g., K(NH 2 ) x H 1−x , Rb(NH 2 ) x H 1−x , and Cs(NH 2 ) x H 1−x , via the exchange of NH 2 − /H − anions with the change of the lattice cell of the solid solution. Extending the research in this direction, we study the M− N−H solid solution in the MNH 2 −MH systems (M = K, Rb, Cs, and their combinations), i.e., KNH 2 −RbH, RbNH 2 −KH, RbNH 2 −CsH, and CsNH 2 −RbH via ex situ/in situ XRD, IR, and 1 H 2D solid-state NMR. The results obtained confirm the formation of mixed metal amide-hydride solid solutions associated with an exchange between both anionic (NH 2− and H − ) and cationic species (K + , Rb + , and Cs + ). With this study, we aim to create an accessible library of M−N−H solid solutions for further studies as additives for hydrogen storage materials or ionic conductors.

“…Among them, magnesium hydride (MgH 2 ), which has high hydrogen storage capacity, excellent reversibility and abundant availability, is regarded as one of the most marvelous candidates for potential hydrogen storage. [9][10][11][12] Unfortunately, the widespread practical application of MgH 2 is retarded by the sluggish dynamic performance and high thermodynamics operation temperature.…”
