Expression analysis of cold stress-inducible genes in wild-type and OsDIRP1-overexpressing transgenic rice plants. Light-grown, 10-day-old wild-type and Ubi:OsDIRP1-sGFP transgenic plants were exposed to cold (4°C) stress for 0 or 24 h. The induction patterns of five stress-responsive genes, OsDREB1A, OsDREB1B, OsDREB1D, GAD, and MRP4, were analyzed by real-time qRT-PCR. The relative expression of each gene was normalized to that of OsActin. Data are means ± SE (P < 0.05, ∗∗P < 0.01, Student’s t-test) of three independent experiments.
