Enhanced sensitivity of CaOSR1-OX transgenic Arabidopsis lines to ABA. (A) Germination rates of CaOSR1-OX mutants and wild-type (WT) plants on 0.5 × Murashige and Skoog (MS) medium supplemented with various concentrations of ABA. (B,C) Seedling development of CaOSR1-OX mutants and wild-type plants exposed to ABA. The numbers of seedlings in each line with expanded cotyledons were counted (C) and representative photographs were taken 5 days after plating (B). Data represent the mean ± standard error of three independent experiments, each evaluating 36 seeds. (D,E) Root elongation of wild-type and transgenic lines exposed to ABA. The root lengths of each plant were measured 8 days after sowing (E) and representative images were taken (D). Data represent the mean ± standard error of three independent experiments, each evaluating 36 seeds. Different letters indicate significant differences between wild-type and transgenic lines (P < 0.05; ANOVA followed by Fisher's LSD test).
