The micronutrient iron is essential for phytoplankton growth due to its central role in a wide
variety of key metabolic processes including photosynthesis and nitrate assimilation. As a …

Photosynthetic carbon (C) fixation by phytoplankton in the Southern Ocean (SO) plays a
critical role in regulating air–sea exchange of carbon dioxide and thus global climate. In the …

Primary production in the Southern Ocean highly depends on phytoplankton and has been
reported to be limited by the availability of the micronutrient iron. The aim of this review is to …

Marine microeukaryotes play a fundamental role in biogeochemical cycling through the
transfer of energy to higher trophic levels and vertical carbon transport. Despite their global …

Predicting responses of plankton to variations in essential nutrients is hampered by limited
in situ measurements, a poor understanding of community composition, and the lack of …

Releases of crude oil and other types of oil from numerous sources can impose catastrophic
physical, chemical, and biological effects on aquatic ecosystems. While currently-used oil …

Numerous cellular functions including respiration require iron. Plants and phytoplankton
must also maintain the iron-rich photosynthetic electron transport chain, which most likely …

Iron uptake by diatoms is a biochemical process with global biogeochemical implications. In
large regions of the surface ocean diatoms are both responsible for the majority of primary …

Transcriptional coordination is a fundamental component of prokaryotic and eukaryotic cell
biology, underpinning the cell cycle, physiological transitions, and facilitating holistic …

Iron is one of the most abundant elements on Earth, and it is essential for life. Despite the
abundance of iron, its chemistry leads to very limited bioavailability, which has resulted in …
