ABA Sensitivity of pub19 Plants.
(A) ABA dose-response analysis of germination in different genotypes of plants. Seeds were germinated for 72 h on plates containing a range of ABA concentrations (0, 0.5, 1, and 1.5 μM). Germination rates represented by the chart are based on three repeated experiments (n = 90).
(B) Growth of different genotypes of plants on ½MS medium containing 0.5 μM ABA. Seeds were germinated and grown for 11 d. Bar = 0.5 cm.
(C) Quantitative analysis of root growth. The experiment was performed in triplicate (n = 12) and repeated three times. Bars indicate standard errors.
(D) Phenotypic comparison of root length in the MS medium with or without ABA (Bar = 1 cm).
