The unicellular picocyanobacterium Prochlorococcus is the most abundant photoautotroph
and contributes substantially to global CO 2 fixation. In the vast euphotic zones of the open …

Lipids are structurally diverse biomolecules that serve multiple roles in cells. As such, they
are used as biomarkers in the modern ocean and as paleoproxies to explore the geological …

The ocean–atmosphere exchange of CO2 largely depends on the balance between marine
microbial photosynthesis and respiration. Despite vast taxonomic and metabolic diversity …

In the nitrogen-limited subtropical gyres, diazotrophic cyanobacteria, including
Crocosphaera, provide an essential ecosystem service by converting dinitrogen (N2) gas …

Common culturing techniques and priorities bias our discovery towards specific traits that
may not be representative of microbial diversity in nature. So far, these biases have not been …

Photosynthesis fuels primary production at the base of marine food webs. Yet, in many
surface ocean ecosystems, diel-driven primary production is tightly coupled to daily loss …

Cyanobacteria, the most abundant photosynthetic organisms in oceans, are tightly
associated with diverse microbiota. However, the relationships between heterotrophic …

Cross-feeding involves microbes consuming exudates of other surrounding microbes,
mediating elemental cycling. Characterizing the diversity of cross-feeding pathways in …

Background Marine heterotrophic flagellates (HF) are dominant bacterivores in the ocean,
where they represent the trophic link between bacteria and higher trophic levels and …

Marine phytoplankton are a diverse group of photoautotrophic organisms and key mediators
in the global carbon cycle. Phytoplankton physiology and biomass accumulation are closely …
