• The elemental stoichiometry and composition of an iron‐limited diatom (2005, background): “Maldonado and Price (2000) attributed this phenomenon to an inducible Fe (III) reductase in nitrate-grown cells that increased the bioavailable pool of Fe for transport.”
• 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).”
• Marine diatom uptake of iron bound with natural colloids of different origins (2003, background): “Both photoreduction and biological reduction (such as plasma membrane ferrireductase) have been proposed to convert the organic-complexed Fe to inorganic bioavailable Fe species (Jones et al., 1987; Rich and Morel, 1990; Johnson et al., 1994; Weger, 1999; Gerringa et al., 2000; Maldonado and Price, ”
• Adaptive strategies by Southern Ocean phytoplankton to lessen iron limitation: Uptake of organically complexed iron and reduced cellular iron requirements (2011, methodology): “Although we do not have direct evidence of a reductive Fe transport pathway for Southern Ocean diatoms, we note that previous evidence of this pathway in marine phytoplankton has come exclusively from diatom isolates (SoriaDengg and Horstmann 1995; Maldonado and Price 2000, 2001).”
• Plankton copper requirements and uptake in the subarctic Northeast Pacific Ocean (2009, background): “1 nmol L 1 unbound DFB present in our experimental bottles should not have artificially induced Fe-limitation, since laboratory studies have shown that 40nmol L 1 excess DFB (400-fold higher than in our bottles) had little effect on the growth rate of one diatom species (Maldonado and Price, 2000).”
• REDUCTION AND TRANSPORT OF ORGANICALLY BOUND IRON BY THALASSIOSIRA OCEANICA (BACILLARIOPHYCEAE) (2001, methodology): “Reduction of organically bound Fe appeared to be enzymatically mediated (Maldonado and Price 2000) and thus a function of the density of the reductase, the concentration of chelated Fe, and the rate constant of reduction.”
