Constitutive expression of SsMAX2 promoted osmotic and drought stress resistance in Arabidopsis. (A) Phenotype of SsMAX2 OE lines, max2, and wild-type (WT) in half MS medium containing 150 and 300 mM mannitol; (B) Phenotype of different Arabidopsis lines after withholding water and rewatering treatment; (C) Survival rate of seedlings after drought treatment; (D) Maximum photochemical efficiency of PSII (Fv/Fm) of different lines under drought stress; (E) Water loss rate. Data are presented as means ± SD of three biological replicates. Significant differences were determined by Student’s t-test. Significance level: * p < 0.05, ** p < 0.01.
