Relative expression patterns of the DRILs in response to abiotic stresses. Fifteen-day-old rice seedlings were exposed to drought (air-drying), salt (400 mM NaCl), ABA (100 µM abscisic acid), and cold (4 °C). Leaves from the rice plants were harvested at the indicated times after treatment. The left graph shows expression in the shoot, and the right graph shows expression in the root. OsUBIQUITIN1 (OsUbi1) was used as an internal control for normalization. Data represent the mean value and standard deviation (n = 3). Significant differences from the mock 0 h control are indicated by asterisks (unpaired Student’s t-test, *P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001)
