| Description |
over-expression of PPDK during senescence can significantly accelerate nitrogen remobilization from leaves, and thereby increase rosette growth rate and the weight and nitrogen content of seeds |

PPDK | | Organism |
Arabidopsis thaliana | | Description |
The enzyme pyruvate,orthophosphate dikinase (PPDK) interconverts pyruvate and phosphoenolpyruvate. PPDK are up-regulated in naturally senescing leaves. The abundance of PPDK protein increases during natural senescence. |
