Intracellular distribution of DMAPP in illuminated leaves of cottonwood
| Sample No. | Total DMAPP in Gradient Fractions | Distribution of DMAPP

|---|---|---|---|
| Chloroplast | Cytosol | ||
| nmol | % | ||
| 1 | 12.49 | 65 | 35 |
| 2 | 10.21 | 71 | 29 |
Values are presented from two separate experiments. For each experiment, fully exposed leaves were sampled directly into liquid nitrogen at midday, incident PPFD = 1,500 μE. Distributions were calculated according to a two-compartment model as described in “Materials and Methods.”
