PP2A-type protein phosphatase subunit single mutants exhibit a reduced ABA sensitivity during seed germination. A and B, Time-dependent seed germination of Col-0 and indicated pp2a single mutants in the presence of 0 (A) or 1 μm ABA (B). C and D, Seed germination on day 4 after stratification (C) and cotyledon expansion on day 7 after stratification (D) in the presence of 0 (blue bars) or1 μm ABA (red bars). Means ± sem (n = 4) with 49 seeds per n normalized to the seed count. Statistical values for differences between the Col-0 wild type and the pp2a single-mutant lines were calculated using two-way ANOVA. *, P < 0.05; **, P < 0.01.
