Dc3-driven GUS expression in tobacco seedlings exposed to dehydration, in the presence (+) or absence (0) of fluridone
| Plant Part and Treatment | GUS Expression
|
|
|---|---|---|
| 0 h Dehydration | 24 h Dehydration | |
| pmol mg−1 protein min−1 | ||
| Roots | ||
| 0 Fluridone | 2.1 (0.56) | 53.7 (4.3) |
| + Fluridone | 1.4 (0.18) | 2.0 (0.30) |
| Shoots | ||
| 0 Fluridone | 3.0 (0.95) | 61.6 (6.4) |
| + Fluridone | 2.3 (0.46) | 1.9 (0.11) |
Values are means from three independent experiments with the −599 line; se values are in parentheses. Zero time corresponds to the end of the pretreatment with fluridone, immediately before the start of dehydration.
