RD29A:LUC Luminescence Is Hyper-Induced by Osmotic Stress in hos3-1.
(A) Seedlings on plates (bottom frames) and respective luminescence images (top frames) were treated with 300 mM NaCl, 100 μM ABA or 24 h cold treatment at 0°C from left to right. hos15 was used as a positive control.
(B) Sensitivity to stress of hos3-1 was determined by comparing the luminescence of the mutant seedlings (grey bars) with that of the wild-type C24 (RD29A:LUC) (open bars) after treatment with 300 mM NaCl, 100 μM ABA or 24 h cold treatment at 0°C. Means and standard errors were determined by ANOVA with a confidence interval of α = 0.05. Error bars represent ±1 SE.
