Their … Webnism underlying the uptake and translo-cation of Cd in plants is not completely understood, some iron (Fe) transporters reported to take up Cd as well as Fe.1 Fe deficiency in plants induces expression of Fe transporters that enhance uptake and translocation. As a result, Cd uptake and translocation are also enhanced in rice during Fe acquisition.
