Arsenic uptake and toxicity in plants: integrating mycorrhizal influences (2010, background): “It is now recognised as a serious threat to human health, as a consequence of consumption of contaminated plant material (Fitz and Wenzel 2002; Meharg 2004; Meharg and Hartley-Whitaker 2002; Smith et al. 1998).”
Mechanisms of Arsenic Hyperaccumulation in Pteris vittata. Uptake Kinetics, Interactions with Phosphate, and Arsenic Speciation1 (2002, background): “Because arsenate is readily reduced intracellularly to arsenite in plant cells (Meharg and Hartley-Whitaker, 2002), the differences in extraction efficiencies may reflect differences in toxicology.”
Genetic mapping of the rice ionome in leaves and grain: identification of QTLs for 17 elements including arsenic, cadmium, iron and selenium (2010, background): “This relationship between these QTLs could be important as it has been proposed that P and As concentration are closely linked because arsenate is transported through phosphate transporters (Meharg and Hartley-Whitaker 2002).”
Transporters of arsenite in rice and their role in arsenic accumulation in rice grain (2008, background): “Plants take up arsenate, the predominant form of As in aerobic soils, through phosphate transporters (12, 13).”
