Other claims from this paper (7)
- Mechanism GA-treated aleurone sensitivity to H2O2 results from decreased ROS metabolism.
- Intervention effect GA strongly down-regulated amounts and activities of catalase, ascorbate peroxidase and superoxide dismutase.
- Intervention effect GA rapidly reduced CAT activity, protein and Cat2 mRNA.
- Intervention effect ABA increased CAT amount and activity and Cat2 mRNA.
- Intervention effect ABA maintained high ascorbate peroxidase and superoxide dismutase amounts.
- Mechanism Loss of ROS scavenging in GA-treated cells ultimately causes oxidative damage and death.
- Intervention effect ABA-treated cells maintained ROS scavenging and remained viable.
