From protists to humans, all animals and plants are inhabited by microbial organisms. There
is an increasing appreciation that these resident microbes influence the fitness of their plant …

Chemosynthetic symbioses between bacteria and marine invertebrates were discovered 30
years ago at hydrothermal vents on the Galapagos Rift. Remarkably, it took the discovery of …

Viruses are ubiquitous in the oceans, exhibiting high abundance and diversity. Here, we
systematically analyze existing genomic sequences of marine prokaryotes to compile a …

Nitrogen cycling is normally thought to dominate the biogeochemistry and microbial ecology
of oxygen-minimum zones in marine environments. Through a combination of molecular …

Our understanding of prokaryote–eukaryote symbioses as a source of evolutionary
innovation has been rapidly increased by the advent of genomics, which has made possible …

Simultaneous characterization of taxonomic composition, metabolic gene content and gene
expression in marine oxygen minimum zones (OMZs) has potential to broaden perspectives …

Oxygen minimum zones, also known as oceanic “dead zones,” are widespread
oceanographic features currently expanding because of global warming. Although …

Deep-sea vents support productive ecosystems driven primarily by chemoautotrophs.
Chemoautotrophs are organisms that are able to fix inorganic carbon using a chemical …

Bacteria of the SAR11 clade constitute up to one half of all microbial cells in the oxygen-rich
surface ocean. SAR11 bacteria are also abundant in oxygen minimum zones (OMZs), where …

Possibly the last discovery of a previously unknown major ecosystem on Earth was made
just over half a century ago, when researchers found teaming communities of animals …
