Disassembling Iron Availability to Phytoplankton
The bioavailability of iron to microorganisms and its underlying mechanisms have far reaching repercussions to many natural systems and diverse fields of research, including ocean biogeochemistry, carbon cycling and climate, harmful algal blooms, soil and plant research, bioremediation, pathogenesis, and medicine. Within the framework of ocean sciences, short supply and restricted bioavailabili...
متن کاملAvailability of iron from iron-storage proteins to marine phytoplankton
We examined the bioavailability of iron-storage proteins—including representatives of maxiand miniferritins—to various species of marine phytoplankton. Both eukaryotic and prokaryotic species were able to grow rapidly with horse spleen ferritin (HoSF) or deoxyribonucleic acid (DNA)-binding proteins from starved cells (Dps) from Trichodesmium erythraeum as the sole Fe source in the medium. In th...
متن کاملEffect of ocean acidification on iron availability to marine phytoplankton.
The acidification caused by the dissolution of anthropogenic carbon dioxide (CO2) in the ocean changes the chemistry and hence the bioavailability of iron (Fe), a limiting nutrient in large oceanic regions. Here, we show that the bioavailability of dissolved Fe may decline because of ocean acidification. Acidification of media containing various Fe compounds decreases the Fe uptake rate of diat...
متن کاملComparative metatranscriptomics identifies molecular bases for the physiological responses of phytoplankton to varying iron availability.
In vast expanses of the oceans, growth of large phytoplankton such as diatoms is limited by iron availability. Diatoms respond almost immediately to the delivery of iron and rapidly compose the majority of phytoplankton biomass. The molecular bases underlying the subsistence of diatoms in iron-poor waters and the plankton community dynamics that follow iron resupply remain largely unknown. Here...
متن کاملAvailability of iron and major nutrients for phytoplankton in the northeast Atlantic Ocean
Because of recent findings that Fe is a limiting factor for phytoplankton activity even at relatively high dissolved iron (DFe) concentrations, the potential importance of Fe limitation was revisited in the northeast Atlantic Ocean (39–458N, 17–218W). We report data gathered during deck incubation experiments performed at three stations in February–March 2001 with surface seawater containing DF...
