Fig. 2.

Nicotianamine (NA) and 2′-deoxymugenic acid (DMA) levels (µg g⁻¹ FW) in roots, leaves, and unpolished seeds of wild-type (WT) rice and three different T₂ transgenic lines co-expressing OsNAS1 and HvNAATb (EYI-9, EYI-89, and EYI-98). FW, fresh weight. Asterisks indicate a statistically significant difference between wild-type and transgenic plants as determined by Student’s t-test (P<0.05; n=3). Both the wild-type and transgenic lines were grown under nutrient-sufficient conditions and seeds were harvested at physiological maturity.
