Nitrogen fixation is an important process connecting the vast atmospheric pool of di‐nitrogen
gas to the biosphere. Nitrogen fixation is an energy intensive process, and it is historically …

Nitrogen fixation is a widespread metabolic trait in certain types of microorganisms called
diazotrophs. Bioavailable nitrogen is limited in various habitats on land and in the sea and …

Previous studies have deciphered the genomic basis of host‐symbiont metabolic
complementarity in vestimentiferans, bathymodioline mussels, vesicomyid clams and …

Osedax, the deep-sea annelid found at sunken whalefalls, is known to host
Oceanospirillales bacterial endosymbionts intracellularly in specialized roots, which help it …

Thiotrophic symbioses between sulphur‐oxidizing bacteria and various unicellular and
metazoan eukaryotes are widespread in reducing marine environments. The giant colonial …

Less than a handful of cuboid and squared cells have been described in nature, which
makes them a rarity. Here, we show how Candidatus Thiosymbion cuboideus, a cube-like …

The mutualism between the thioautotrophic bacterial ectosymbiont Candidatus Thiobius
zoothamnicola and the giant ciliate Zoothamnium niveum thrives in a variety of shallow …

Eukaryotes may experience oxygen deprivation under both physiological and pathological
conditions. Because oxygen shortage leads to a reduction in cellular energy production, all …

Osedax, the deep-sea annelid found at sunken whalefalls, is known to host
Oceanospirillales bacterial endosymbionts intracellularly in specialized roots, that help it …

FtsZ, the bacterial tubulin-homolog, plays a central role in cell division and polymerizes into
a ring-like structure at midcell to coordinate other cell division proteins. The rod-shaped …
