Expression levels of some salt-responsive genes in wild-type and transgenic plants. (A) OsLEA3; (B) OsRab16A; (C) OsDREB2A. Total RNA was extracted from the 14-d-old rice seedlings grown under control (open columns) and salt stress (200 mM NaCl, filled columns) conditions for 24 hours. The transcript levels were measured by real-time reverse-transcription PCR. Actin was used as an internal control. Data are mean±SE of three replicates. Asterisks indicate statistically significant differences (P < 0.05) between wild-type (WT) and transgenic lines (OE and Ri).
