Fe and Zn concentrations in T2 seeds obtained from plants cultured in small pots fertilized with nutrient solution. T2 seeds from the main tillers of NT, 35S-HvNAS1 (35S), and OsActin1-HvNAS1 (AN1, AN2, and AN3) lines were harvested and subjected to metal concentration analysis. a Fe concentration in polished rice seeds. b Zn concentration in polished rice seeds. c Fe concentration in brown rice seeds. d Zn concentration in brown rice seeds. e Fe concentration in bran. f Zn concentration in bran. g Fe concentration in hulls. h Zn concentration in hulls. The data represent the mean ± standard error of six independent pots. Distinct letters above the bars indicate significant differences (p < 0.05).
