Figure 5.

ahk mutants display Suc sensitivity. A, Seedlings were grown for 10 d in media with increasing concentrations of Suc in a range from 60 to 360 mm and scored after this time for seedling survival. Suc concentrations below 120 mm did not cause lethality in any of the genotypes tested and above 300 mm prevented seedlings survival. Genotypes used are the same as in previous figures and OE represents one 35S-AHK3 overexpressing line. Vertical bars represent sds from two replica experiments in which 40 seedlings per genotype and experiment were scored. B, Ten-day-old plants from the same genotypes grown at 275 mm Suc or mannitol.
