Decreasing arsenic accumulation in rice by overexpressing OsNIP1;1 and OsNIP3;3 through disrupting arsenite radial transport in roots

What is it about?

Rice roots take up arsenite efficiently through the highly expressed silicon uptake pathway. Here, we show that overexpression of genes encoding arsenite-permeable aquaporin channels reduces arsenic accumulation in rice shoots and grain by restricting arsenite loading into the xylem for translocation.
