Plant growth promoting rhizobacteria and endophytes accelerate phytoremediation of metalliferous soils. (2011, background): “…(Chakraborty et al., 2006; Sikora et al., 2007), improved mineral uptake (Dimkpa et al., 2009a), associative nitrogen fixation (Dobbelaere et al., 2003), tolerance to abiotic stresses (Sziderics et al., 2007; Belimov et al., 2009;Dimkpa et al., 2009a), or production of phytohormones (Vessey, 2003).”
Effect of Trichoderma asperellum strain T34 on iron, copper, manganese, and zinc uptake by wheat grown on a calcareous medium (2011, background): “Fungal siderophores have been found to increase the Fe supply to plants and to decrease the plant capacity to absorb other metals ( Dimkpa et al. 2009 ).”
CuO and ZnO nanoparticles: phytotoxicity, metal speciation, and induction of oxidative stress in sand-grown wheat (2012, methodology): “Evaluation of IAA and glutathione oxidation in roots and shoots of NP-treated plants The potential oxidation of IAA by IAA oxidase was evaluated according to previously described procedures (Dimkpa et al. 2009).”
Fortification of micronutrients for efficient agronomic production: a review (2016, background): “Here, siderophores, metal chelators produced by beneficial microbes in response to Fe scarcity, play a role in depriving pathogens of Fe, as well as in availing plants with Fe and other metallic micronutrients (Kloepper et al. 1980; Lim and Kim 1997; Vansuyt et al. 2007; Dimkpa et al. 2009, 2015a).”
Characterization of plant growth-promoting bacteria associated with rice cropped in iron-stressed soils (2014, unknown): “Dimkpa et al. (2009b) observed that the presence of metals such as Al, cadmium, and nickel, including iron, inhibited auxin production in Streptomyces sp. but that auxin production was enhanced under siderophore-producing conditions.”
A simple double-layered chrome azurol S agar (SD- CASA) plate assay to optimize the production of siderophores by a potential biocontrol agent Bacillus (2011, background): “These compounds are generically known as siderophores and they are typically found in iron-deficient cultures (Dimkpa et al., 2009).”
Perspectives of plant-associated microbes in heavy metal phytoremediation. (2012, background): “Similarly, Dimkpa et al. (2009b) found that the AC C EP TE D M AN U SC R IP T siderophores produced by Streptomyces tendae F4 significantly enhanced uptake of Cd by sunflower plant.”
