Figure 2.abc- mutant is hypersensitive to ABA during germination. (A) Sterilized and stratified WT, abc-, abc- +c and ein3-1 seeds were plated on ATS agar medium supplemented with the indicated concentrations of ABA and incubated in the growth chamber. (B) Sterilized and stratified WT, abc- and abc- +c seeds were plated on ATS agar supplemented with ABA, ACC or the combination of both as indicated. In (A) and (B) the percentage of germination was scored after 24 h. Approximately, 100 seeds were processed per line in each experiment. Data are mean values (± SE) of five independent experiments. Different letters indicate a significant difference at p < 0.05 (Tukey's test).
