Iron requirements of the pennate diatom Pseudo‐nitzschia: Comparison of oceanic (high‐nitrate, low‐chlorophyll waters) and coastal species (2006, background): “…cell size (Brand et al. 1983; Sunda and Huntsman 1995; Maldonado and Price 1996), replacing iron-containing enzymes and proteins with iron-free equivalents (La Roche et al. 1993), and expressing an inducible high-affinity iron transport system (Harrison and Morel 1986; Maldonado and Price 2001).”
Copper‐dependent iron transport in coastal and oceanic diatoms (2006, methodology): “2 in Maldonado and Price 2001) and determined spectrophotometrically as previously described (manual method) (Maldonado and Price 2000).”
Plankton copper requirements and uptake in the subarctic Northeast Pacific Ocean (2009, methodology): “The ability of an extracellular bound enzyme to reduce organically complexed Cu(II), as is the case for Fe(III) (Maldonado and Price, 2001), should be directly proportional to the half redox potential (E1/2) of the chelated metal species.”
Cellular iron contents of plankton during the Southern Ocean Iron Experiment (SOFeX) (2004, background): “, internalize) Fe(III) bound to both synthetic ligands and natural colloids (Hutchins et al., 1999; Maldonado and Price, 2001; Chen et al., 2003), potentially by converting externally bound organically complexed Fe to inorganic bioavailable Fe with ferrireductase enzymes embedded in the plasma membr”
Iron‐light interactions differ in Southern Ocean phytoplankton (2012, background): “…experiments of iron uptake and iron reductase activity in marine phytoplankton have been conducted in the dark to avoid photochemical reactions (Maldonado and Price 2001), recent data show that iron uptake from non-photolabile Fe-DFB complexes during short-term experiments (8–15 h) by P.…”
Adaptive strategies by Southern Ocean phytoplankton to lessen iron limitation: Uptake of organically complexed iron and reduced cellular iron requirements (2011, methodology): “Stock DFB solutions (0.1– 10 mmol L21) were prepared as previously described (Maldonado and Price 2001).”
The elemental stoichiometry and composition of an iron‐limited diatom (2005, background): “…of the photosynthetic apparatus (Greene et al. 1991; Geider et al. 1993; Moseley et al. 2002), in the amounts of cellular Fe required for growth (Sunda and Huntsman 1995; Maldonado and Price 1996), and in the pathways of Fe acquisition (Harrison and Morel 1986; Maldonado and Price 2000, 2001).”
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).”

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).”
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).”
