Mutation of OsNramp5 reduces the partitioning of soil-derived Cd to grains of lower-node tillers in ratoon rice.

Enhanced cadmium (Cd) uptake in lower-node tillers increases the contamination risk in ratoon rice. Using OsNramp5 mutants and seasonal Cd treatments, we quantified the contributions of stubble-redistributed Cd and newly soil-derived Cd to ratoon tillers at different nodal positions. OsNramp5 loss-of-function reduced g...
