Some diatoms of the genera Pseudo-nitzschia and Nitzschia produce the neurotoxin domoic
acid (DA), a compound that caused amnesic shellfish poisoning (ASP) in humans just over …

Diatoms are one of the most successful group of photosynthetic eukaryotes in the
contemporary ocean. They are ubiquitously distributed and are the most abundant primary …

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 …

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 …

Micronutrients control phytoplankton growth in the ocean, influencing carbon export and
fisheries. It is currently unclear how micronutrient scarcity affects cellular processes and how …

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 …

Phytoplankton have evolved a capability to acquire phosphorus (P) from dissolved organic
phosphorus (DOP) since the preferred form, dissolved inorganic phosphate (DIP, or Pi), is …

Diatoms account for∼ 20% of global primary production, often limited by the availability of
Fe and other trace nutrients such as Cu. The present study examined the role of both metals …

Cyanobacteria use a series of adaptation strategies and a complicated regulatory network to
maintain intracellular iron (Fe) homeostasis. Here, a global activator named IutR has been …

The Southern Ocean (SO) harbors some of the most intense phytoplankton blooms on Earth.
Changes in temperature and iron availability are expected to alter the intensity of SO …
