Quantitative RT-PCR analysis of OsNRAMP1. (A) Total RNA was extracted from roots or shoots of Sasanishiki (Sa) and Habataki (Ha) grown in the absence (control) or presence of 0.2 or 1 μM CdCl₂ for 1 week. (B) Total RNA was extracted from the roots or the shoots of Sasanishiki (Sa), Nipponbare (Ni), Tsukinohikari (Ts), Habataki (Ha), Jarjan (Ja), Anjana Dhan (An), and Cho-ko-koku (Ch) grown without Cd. (C) Total RNA was extracted from the roots or shoots of Sasanishiki (Sa) and Habataki (Ha) grown for 1 week under Fe-deficient conditions. The results are presented as the means ±SD of triplicate samples. Different letters indicate significant differences at P <0.01 by the Tukey–Kramer test.
