Short-term acidification promotes diverse iron acquisition and conservation mechanisms in upwelling-associated phytoplankton

Coastal upwelling regions are among the most productive marine ecosystems but may be threatened by amplified ocean acidification. Here the authors show from community to molecular levels that phytoplankton in an upwelling region respond to short-term acidification exposure with iron uptake pathways and strategies that reduce cellular iron demand.

Evolution and regulation of nitrogen flux through compartmentalized metabolic networks in a marine diatom

Here, using the diatom Phaeodactylum tricornutum as a model organism, the authors combine functional genomics, phylogenetics, and metabolic modeling to describe how diatoms might have functionally integrated nitrogen metabolism during evolution and how metabolic flux is regulated across cellular compartments

Carbonate-sensitive phytotransferrin controls high-affinity iron uptake in diatoms

Phytotransferrin, a functional analogue of transferrin, has an obligate requirement for carbonate to bind iron, which suggests that acidification-driven declines in the concentration of seawater carbonate ions may negatively affect diatom iron acquisition.
