Table 1. Concentrations of Fe and Zn in unpolished and polished grain of WT and transgenic rice.
| Genotype | Unpolished (µg g−1) | Polished (µg g−1) | % Fe in polished | % Zn in polished | ||
| Fe | Zn | Fe | Zn | |||
| WT | 22 | 42 | 4.5 | 34 | 21 | 81 |
| OE- OsNAS1S | 47 | 63 | 9.7 | 48 | 21 | 76 |
| OE- OsNAS2B | 64 | 91 | 19 | 76 | 30 | 84 |
| OE- OsNAS2J | 54 | 68 | 14 | 52 | 26 | 77 |
| OE- OsNAS3B | 51 | 65 | 9.9 | 49 | 19 | 75 |
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.
