The role of unchelated Fe in the iron nutrition of phytoplankton (2008, methodology): “Line 1: Fe9 model (Hudson and Morel 1990); line 2: Fe(II)s model (Shaked et al. 2005); line 3: FeL model (Salmon et al.”
Adaptive strategies by Southern Ocean phytoplankton to lessen iron limitation: Uptake of organically complexed iron and reduced cellular iron requirements (2011, background): “…(1995) reported uptake of Fe from FeDFB by the coastal diatom, Phaeodactylum tricornutum, Hutchins et al. (1999) the uptake of several Fe-siderophore complexes by the coastal diatoms Skeletonema costatum and T. weissflogii, and Shaked et al. (2005) uptake of Fe from FeDFB by T. weissflogii.”
Effects of iron limitation on intracellular cadmium of cultured phytoplankton: Implications for surface dissolved cadmium to phosphate ratios (2009, background): “This suggests that Cd is interacting with a putative non-specific divalent metal transporter, and not the high-affinity Fe transport system described by Maldonado and Price (2001), Shaked et al. (2005) , Maldonado et al. (2006), and Kustka et al. (2007).”
Comprehending crystalline β-carotene accumulation by comparing engineered cell models and the natural carotenoid-rich system of citrus (2011, unknown): “Iron uptake in these related organisms has been described by the so-called Fe(II)s mechanism (Shaked et al., 2005) where reduction of free Fe(III)’ is the seminal step.”
Some thoughts on the concept of colimitation: Three definitions and the importance of bioavailability (2008, unknown): “…that the reservoir of complexed metals is available to some fraction of the phytoplankton community through specialized uptake systems such as iron reductases or metallophore (siderophore or cobalophore) acquisition pathways (Maldonado and Price 2001; Saito et al. 2002; Shaked et al. 2005).”
Dust- and mineral-iron utilization by the marine dinitrogen-fixer Trichodesmium (2011, background): “Several pathways such as thermal dissolution, mobilization by organic ligands, photoreduction and bio-reduction may be involved in the Trichodesmium -mediated dissolution of iron mineral”
Plankton copper requirements and uptake in the subarctic Northeast Pacific Ocean (2009, background): “Rigorous physiological and genomic studies on Fe acquisition have demonstrated organic Fe utilization by a number of diatom species (Maldonado and Price, 2000, 2001; Shaked et al., 2005; Maldonado et al., 2006; Kustka et al., 2007).”
Extracellular production of superoxide by marine diatoms: Contrasting effects on iron redox chemistry and bioavailability (2005, background): “Several studies with marine diatoms indicate that reduction may be a necessary step for Fe uptake from various chelates (Anderson and Morel 1980; Allnutt and Bonner 1987; Maldonado and Price 2001), and we have also found this to be the case when Fe is buffered by EDTA (Shaked et al. 2005).”
Copper‐dependent iron transport in coastal and oceanic diatoms (2006, background): “Indeed, a new kinetic model for Fe uptake by marine diatoms supports these findings and predicts that extracellular reduction of all Fe species is a necessary step for iron acquisition (Shaked et al. 2005).”
