Man represses germination of wild-type Arabidopsis seeds in a concentration-dependent manner. Seeds were plated in the absence of sugar (control) and on 2, 5, 7.5, and 15 mm Man. Fifteen millimolar mannitol (15 Mtl) was taken as an osmotic control. Approximately 200 seeds were used for each data point in each experiment. Values presented are the average of three independent experiments. Germination was scored at d 8.
