The iU1 plants increased the ABA contents under salt treatments. (A) Inhibition of seed germination by exogenous ABA. (B) Seed germination rate. Seeds were sown on agar plates supplemented with or without ABA. Data are presented as the means ± SD of at least 12 biological replicates. Each replicate contained ~40 seeds. (C) ABA contents of germinating seeds. Seeds germinated on MS or 200 mM NaCl medium for 1, 3, 5, or 14 days were harvested, and ABA was extracted and analyzed by LC/MS. The ABA-deficient mutant gin1-3 (also known as aba2) was used as an internal control. Data represent the means ± SD of three or four biological replicates. ^*p < 0.05, Student’s t-test.
