Figure 3. Osmotic stress hypersensitivity of ML1:FUS3 seeds and glucose hypersensitivity of 35S:AKIN10 seeds are both partially dependent on de novo ABA synthesis. Germination (radicle protrusion) of 35S:AKIN10 and ML1:FUS3 seeds 2 d after imbibition on MS, 10 µM fluridone (FLU), 3% sorbitol (sor) ± 10 µM FLU, and 3% glucose (glc) ± 10 µM FLU. Averages from 3 experiments ± SD are shown. 100–150 seeds were used in each experiment.
