Levels of Cd (unpolished seeds and endosperm), Fe and Zn (endosperm) in wild-type (WT) rice and T₃ transgenic lines co-expressing OsNAS1 and HvNAATb (EYI-9, EYI-89, and EYI-98) grown in the presence of 100 µM FeCl₃ and 10 µM CdCl₂. Asterisks indicate a statistically significant difference between wild-type and transgenic plants as determined by Student’s t-test (P<0.05; n=6). The Cd content of the unpolished seeds and endosperm was significantly different in the wild-type and transgenic lines. Transgenic line EYI-9 did not produce enough seeds for analysis in the presence of Cd, so Fe and Zn levels were not measured in the endosperm. Seeds from the wild-type and transgenic lines were harvested at physiological maturity. (This figure is available in color at JXB online.)
