Figure 6.

Quantitative comparison of labeled sucrose movement within wild-type and mutant plants. Bar graphs with standard deviation indicate distribution of radioactive label in fed wild-type and homozygous mutant plants 5 h after feeding. y axis values are the ratio of radioactivity detected by liquid scintillation counting in indicated organs to the total radioactivity detected for that plant. The organ groupings are as follows: FL, fed rosette leaf; R, roots; I, inflorescences; and R-FL, rosette without fed leaf, i.e., all other rosette leaves.
