| Research Abstract |
In this project, rice and barley aquaporins were selected and analyzed form the view to elucidate the molecular mechanism of arsenite transports in Poaceae plants. Final goal of this project is to breed rice/barley lines containing low As. Using screening system with yeast cells, 5 aquaporin genes (including known 3 genes) were identified as arsenite transporters. Among these genes, temporal increase of OsNIP2 ; 1 expression in roots and decrease of OsNIP3;3 in leaves were observed in rice plants treated with arsenite.
