Down-regulation of NPP1 expression is not accompanied by enhancement of AGPase, UGPase and SuSy activities
| Enzyme activities (mU mg−1) | WT | npp1 |
|---|---|---|
| AGPPase | 95.6 ± 12.2 | 8.0 ± 1.0 |
| AGPase | 101.4 ± 10.0 | 89.5 ± 5.4 |
| UGPPase | 575.6 ± 70.3 | 216.8 ± 103.9 |
| UGPase | 587.4 ± 89.7 | 525.2 ± 68.2 |
| Sucrose synthase | 192.2 ± 24.3 | 205.1 ± 20.0 |
The shoots of WT and npp1 seedlings at 7 d after imbibition were subjected to the enzyme assays.
Values show the means ± SD (n = 10). mU mg−1, nmol min−1 (mg of protein)−1.
