Abstract

Ferritin's role in the oceans The non-haem protein ferritin is used by many plants, animals and microorganisms to store iron in a non-toxic soluble form that can be readily mobilized when required. Ferritin has now been found in the two diatoms, Pseudo-nitzschia and Fragilariopsis, that dominate phytoplankton blooms induced by both natural and artificial oceanic iron supplementation. This is the first report of ferritin in any member of the Stramenopila, the eukaryote lineage that includes many plankton components including unicellular algae, diatoms and macroalgae. Phylogenetic analysis suggests that ferritin arose in this small subset of diatoms via lateral gene transfer, and it may be key to their success in the 30–40% of ocean waters in which iron availability is the factor limiting primary productivity.
