Drought resistance assay of OsGRAS23-overexpressing transgenic rice. a Three-week-old transgenic rice plants and WT plants grown in the 96-well plates and cultivated with culture solution, and exposed to dehydration stress for one day before being transferred to the culture solution. b Survival rate of WT and transgenic lines after dehydration stress. The data represent the mean ± SD (n = 3),*P ≤ 0.05. c, d Seed setting rate and yield of transgenic rice plants under drought stress at the reproductive stage. The data represent the mean ± SD (n = 8),*P ≤ 0.05, ** P ≤ 0.01, t-test
