OsbZIP62V enhanced the tolerance of rice to drought and oxidative stress. a, OsbZIP62V transgenic rice plants and WT plants were cultured in 96-well plates and treated with 20% PEG for 3 days, after which they recovered for 4 days. b, Survival rate of OsbZIP62V transgenic plants and WT plants after PEG-simulated drought stress. The error bars indicate SEs based on three replicates, **P < 0.01 according to Student’s t test. c, Phenotype of OsbZIP62V under oxidative stress. OsbZIP62V lines and WT plants were cultured in 96-well plates and treated with 60 mM H₂O₂ for 5 days, after which they recovered for 3 days. d, Survival rate of OsbZIP62V transgenic plants and control plants after oxidative stress. The error bars indicate SEs based on three replicates. e, Total chlorophyll content in rice leaves. f, Total H₂O₂ content. g, Total MDA content. The data represent the means ± SDs (n = 4 or 5), *P < 0.05, **P < 0.01 according to Student’s t test. FW: fresh weight
