Comparison of chilling tolerance in wild-type and transgenic rice lines overexpressing TaGolS1 or TaGolS2. Fourteen-day-old plants of wild-type (WT) and two independent transgenic lines (GolS 1-1 and GolS 2-2: T2 generation) were subjected to cold at 5°C under continuous light for 14 days. After cold treatment, they were regrown for 14 days at 23–29°C. A. Chilling tolerance of WT, GolS 1-1 and GolS 2-2 transgenic plants. B. Survival rate of WT, GolS 1-1 and GolS 2-2 transgenic plants after chilling treatments. Each data point represents the mean ± standard deviation from three independent experiments. Bars labeled with asterisks show significant differences between WT and transgenic plants by Welch’s t-test at * P = 0.02 and ** P = 0.01.
