Concentrations of Fe and Zn in unpolished and polished grain of WT and transgenic rice.

Grain samples from WT, one transgenic line overexpressing OsNAS1 (OE-OsNAS1S), two independent transgenic lines overexpressing OsNAS2 (OE-OsNAS2B and OE-OsNAS2J) and one transgenic line overexpressing OsNAS3 (OE-OsNAS3B) were analyzed by ICP-OES. The percentage of Fe and Zn concentration in polished grain, relative to unpolished grain concentration, is presented in the last two columns of the table.
