• Rice is more efficient in arsenite uptake and translocation than wheat and barley (2010, background): “…of uptake and translocation, coupled with arsenite mobilisation in submerged paddy soil, is an important reason why rice accumulates excessive levels of As in straw and grain, thus posing a significant health risk to animals and humans (Abedin et al. 2002a; Meharg et al. 2009; Zhu et al. 2008b).”
• Advances in Elucidating Beneficial Interactions Between Plants, Soil, and Bacteria (2013, background): “As inorganic pollutants are either nutrients themselves (e.g., nitrate, phosphate, copper, manganese, zinc) or chemically similar to nutrients (e.g., arsenate, selenate), therefore, plants naturally have transporter proteins for these pollutants (Abedin et al., 2002; Shibagaki et al., 2002).”
• Arsenic Accumulation in Rice and Probable Mitigation Approaches: A Review (2017, background): “[71] found that the bioavailability of arsenic to rice plants follows the order AsIII > MMA >AsV > DMA; all of the species are taken up by rice roots, but the rate of organic species uptake is much lower than that of inorganic arsenic [15].”
• Phytoremediation. (2005, background): “, arsenate is taken up by phosphate transporters, selenate by sulfate transporters) (1, 112).”
• Comparison of mercury, lead and arsenic with respect to genotoxic effects on plant systems and the development of genetic tolerance (2004, result): “Arsenite uptake was active, and was taken up at approximately the same rate as arsenate (Abedin et al., 2002).”
• Arsenic uptake and metabolism in arsenic resistant and nonresistant plant species (2002, background): “…hypothesis is supported, for MMA and DMA, as their uptake from hydroponic solutions has been demonstrated in a number of plant species (Marin et al., 1992, 1993; Carbonell-Barrachina et al., 1998, 1999; Abedin et al., 2002a), including the arsenic hyperaccumulator Pteris vittata (Ma et al., 2001).”
• Genetic mapping of the rice ionome in leaves and grain: identification of QTLs for 17 elements including arsenic, cadmium, iron and selenium (2010, background): “A good example of this is As, which under aerobic conditions is predominantly arsenate, and taken up via phosphate transporters (Abedin et al. 2002), while in anaerobic conditions the arsenic is mainly arsenite and enters the roots via the efficient Si transport pathway (Ma et al.”
• Arsenic uptake and toxicity in plants: integrating mycorrhizal influences (2010, background): “The suggestion that As(III) uptake into rice is active, i.e. energy-dependent, can be discounted, as it was based entirely on the fact that uptake versus concentration showed saturation kinetics (Abedin et al. 2002b).”
