文摘
- •
Drought-induced increase in total G6PDH activity results from enhanced cytosolic G6PDH.
- •
ABA and H2O2 are required for drought-induced increase in cytosolic G6PDH activity.
- •
H2O2 acts downstream of ABA in inducing cytosolic G6PDH activity under drought stress.
- •
Enhanced cytosolic G6PDH activity plays an important role in regulating AsA-GSH cycle.
