Cyanobacteria are the only prokaryotes to have evolved oxygenic photosynthesis,
transforming the biology and chemistry of our planet. Genomic and evolutionary studies …

BACKGROUND Biological dinitrogen (N2) fixation, the reduction of atmospheric N2 to
ammonia, is important for maintaining the fertility of the oceans by providing biologically …

Nitrogen (N) is used in many of life's fundamental biomolecules, and it is also a participant in
environmental redox chemistry. Biogeochemical processes control the amount and form of N …

Nitrogen (N2) fixation in oligotrophic surface waters is the main source of new nitrogen to the
ocean and has a key role in fuelling the biological carbon pump. Oceanic N2 fixation has …

Marine diazotrophs convert dinitrogen (N 2) gas into bioavailable nitrogen (N), supporting
life in the global ocean. In 2012, the first version of the global oceanic diazotroph database …

By controlling nutrient cycling and biomass production at the base of the food web,
interactions between phytoplankton and bacteria represent a fundamental ecological …

In the global effort to reduce CO 2 emissions, the concurrent enhancement of pollutant
degradation and reductions in fossil fuel consumption are pivotal aspects of microalgae …

Nitrogen fixing symbioses between plants and bacteria are ancient and, while not
numerous, are formed in diverse lineages of plants ranging from microalgae to …

Literature covered: early 2000s to late 2017 Bacteria frequently exchange metabolites with
other micro-and macro-organisms. In these often obligate cross-feeding interactions, primary …

Biological dinitrogen (N 2) fixation is a key metabolic process exclusively performed by
prokaryotes, some of which are symbiotic with eukaryotes. Species of the marine haptophyte …
