Other claims from this paper (13)
- Intervention effect SA pretreatment significantly induced freezing tolerance in wheat.
- Intervention effect SA pretreatment maintained relatively higher dark-adapted maximum photosystem II quantum yield.
- Intervention effect SA pretreatment maintained relatively higher electron transport rates.
- Intervention effect SA pretreatment was associated with less cell membrane damage.
- Intervention effect Exogenous SA induced endogenous H2O2 accumulation.
- Mechanism cell wall peroxidase triggered apoplastic endogenous H2O2 accumulation.
- Mechanism membrane-linked NADPH oxidase triggered apoplastic endogenous H2O2 accumulation.
- Intervention effect Dimethylthiourea pretreatment completely abolished SA-induced freezing tolerance.
- Intervention effect Dimethylthiourea pretreatment completely abolished ABA synthesis.
- Intervention effect Fluridone pretreatment reduced H2O2 accumulation.
- Intervention effect Fluridone pretreatment inhibited NADPH oxidase encoding genes expression.
- Intervention effect Fluridone pretreatment partially counteracted SA-induced freezing tolerance.
- Mechanism Endogenous H2O2 and ABA signaling may form a positive feedback loop mediating SA-induced freezing tolerance.
