Expression profile of OsNAC3. (A) OsNAC3 expression in the root, stem, leaf, leaf sheath, and spike of heading stage rice. (B) Dose-dependent expression level of OsNAC3 in rice roots under salt treatment. 5-day-old rice seedlings were exposed to different concentrations of NaCl (0, 25, 50, 75, 100, and 150 mM) for 12 h. (C) Time-course expression level of OsNAC3 in rice roots under 100 mM NaCl treatment. 5-day-old rice seedlings were exposed to 100 mM NaCl for different times (0, 1, 3, 6, 12, and 24 h). (D) Dose-dependent expression level of OsNAC3 in rice roots under ABA treatment. 5-day-old rice seedlings were exposed to different concentrations of ABA (0, 6, 12, 30, 50, and 100 μM) for 12 h. (E) Time-course expression level of OsNAC3 in rice roots under 50 μM ABA treatment. 5-day-old rice seedlings were exposed to 50 μM ABA at different times (0, 1, 3, 6, 12, and 24 h). Histone H3 was used as an internal standard. Data represent means ± SD (n = 3)
