SAR11 is a group of small, carbon-oxidizing bacteria that reach a global estimated
population size of 2.4× 1028 cells—approximately 25% of all plankton. They are found …

Viruses are by far the most abundant'lifeforms' in the oceans and are the reservoir of most of
the genetic diversity in the sea. The estimated 1030 viruses in the ocean, if stretched end to …

The SAR11 clade consists of very small, heterotrophic marine α-proteobacteria that are
found throughout the oceans, where they account for about 25% of all microbial cells …

Microorganisms often form symbiotic relationships with eukaryotes, and the complexity of
these relationships can range from those with one single dominant symbiont to associations …

The compatible solute dimethylsulphoniopropionate (DMSP) has important roles in marine
environments. It is an anti-stress compound made by many single-celled plankton, some …

A microbe's growth rate helps to set its ecological success and its contribution to food web
dynamics and biogeochemical processes. Growth rates at the community level are …

The history of microbial evolution in the oceans is probably as old as the history of life itself.
In contrast to terrestrial ecosystems, microorganisms are the main form of biomass in the …

The oceans contribute significantly to the global emissions of a number of atmospherically
important volatile gases, notably those containing sulfur, nitrogen and halogens. Such gases …

Metagenomic sequencing provides a window into microbial community structure and
metabolic potential; however, linking these data to exogenous metabolites that …

Sulphur is a universally required cell nutrient found in two amino acids and other small
organic molecules. All aerobic marine bacteria are known to use assimilatory sulphate …
