Abstract in another language

Arsenic, cadmium, lead, and mercury are toxic elements that are almost ubiquitouslypresent at low levels in the environment because of anthropogenicinfluences. Dietary intake of plant-derived food represents a major fractionof potentially health-threatening human exposure, especially to arsenic andcadmium. In the interest of better food safety, it is important to reduce toxicelement accumulation in crops. A molecular understanding of the pathwaysresponsible for this accumulation can enable the development of crop varietieswith strongly reduced concentrations of toxic elements in their edibleparts. Such understanding is rapidly progressing for arsenic and cadmiumbut is in its infancy for lead and mercury. Basic discoveries have been madein Arabidopsis, rice, and other models, and most advances in crops have beenmade in rice. Proteins mediating the uptake of arsenic and cadmium havebeen identified, and the speciation and biotransformations of arsenic are nowunderstood. Factors controlling the efficiency of root-to-shoot translocationand the partitioning of toxic elements through the rice node have also beenidentified.
