In addition to control by major nutrient elements (nitrogen, phosphorus, and silicon) the
productivity and species composition of marine phytoplankton communities are also …

Oceanic phytoplankton species have highly efficient mechanisms of iron acquisition, as they
can take up iron from environments in which it is present at subnanomolar concentrations. In …

Nearly all iron dissolved in the ocean is complexed by strong organic ligands of unknown
composition. The effect of ligand composition on microbial iron acquisition is poorly …

Holobionts are species-specific associations between macro-and microorganisms. On coral
reefs, the benthic coverage of coral and algal holobionts varies due to natural and …

Siderophores are strong iron‐binding molecules produced and utilized by microbes to
acquire the limiting nutrient iron (Fe) from their surroundings. Despite their importance as a …

The crossing of environmental barriers poses major adaptive challenges. Rareness of
freshwater-marine transitions separates the bacterial communities, but how these are …

The bioavailability of iron to microorganisms and its underlying mechanisms have far
reaching repercussions to many natural systems and diverse fields of research, including …

Two novel Gram-negative, aerobic, asporogenous, motile, rod-shaped, orange and white
pigmented, designated as LEGU1T and G19T, were isolated from the roots of rice plants …

It is now widely accepted that siderophores play a role in marine iron biogeochemical
cycling. However, the mechanisms by which siderophores affect the availability of iron from …

Phytoplankton are often limited by iron in aquatic environments. Here we examine Fe
bioavailability to phytoplankton by analyzing iron uptake from various Fe substrates by …
