Contrasting Fate of Thallium and Cadmium in the Soil-Rice System: Convergent Rhizosphere Bioavailability Responses Yet Divergent Translocation and Grain Partitioning.
Combined contamination of soils with thallium (Tl) and cadmium (Cd) is widespread. Despite comparable accumulation of Tl and Cd by rice plants, the mechanisms underlying significantly lower Tl concentrations than Cd in grains remain unclear. Here, pot experiments, rhizotron observations and field sampling were combined...
