Overexpression of OsGRAS23 improved tolerance to oxidative stress. a Overexpression and WT rice plants were grown with MV. Total H₂O₂ content (b), relative SOD activity (c), and relative POD activity (d) in the leaves of the transgenic and WT rice plants were measured before MV treatment and after the plants were treated with 30 μM MV for 24 h. Overexpression and WT rice seeds were grown with 3 μM MV (e) and the total chlorophyll contents were measured in the leaves (f). The data represent the mean ± SD (n = 4 or 5), *P ≤ 0.05, ** P ≤ 0.01, t-test, FW: fresh weight
