Other claims from this paper (10)
- Intervention effect Water stress significantly induced OsNCED3, a key ABA biosynthesis gene, in rice.
- Association Induction of OsNCED3 under water stress preceded a rapid increase in ABA in rice.
- Intervention effect Water stress substantially enhanced expression of CATB in rice leaves.
- Intervention effect Exogenously applied ABA promoted CATB expression in rice leaves in a concentration-dependent manner.
- Intervention effect Exogenously applied ABA inhibited CATC expression in rice leaves in a concentration-dependent manner.
- Intervention effect Inhibiting ABA production with nordihydroguaiaretic acid and tungstate subdued CATB expression under water stress in rice.
- Intervention effect Inhibiting ABA production with nordihydroguaiaretic acid and tungstate enhanced CATC expression under water stress in rice.
- Intervention effect Inhibiting endogenous ABA production reduced H₂O₂ accumulation in rice leaves.
- Association H₂O₂ accumulation in rice leaves showed a correlation with total catalase activity.
- Mechanism Water stress-induced ABA appears to prevent excessive H₂O₂ accumulation in rice through induction of CATB expression.
