Other claims from this paper (9)
- Intervention effect Pretreatment with 10 or 20 μM SA for more than 6 h promoted resistance of Arabidopsis seedlings to salt stress.
- Intervention effect Pretreatment with 200 μM SA reduced resistance of Arabidopsis to salt stress.
- Intervention effect SA pretreatment inhibited total respiration of Arabidopsis seedlings.
- Intervention effect SA pretreatment promoted reactive oxygen species generation in Arabidopsis seedlings.
- Intervention effect The ROS content in 10 or 20 μM SA pretreated seedlings decreased to the basal level within 6 h.
- Intervention effect High activities of antioxidant enzymes and alternative oxidase were maintained in 10 or 20 μM SA pretreated seedlings.
- Intervention effect Blocking the alternative oxidase pathway significantly impaired SA-enhanced salt stress resistance.
- Observation SA-mediated salt stress response is dose- and time-dependent.
- Mechanism The effects of SA pretreatment on salt stress tolerance were related to induction of AOX capacity and the antioxidant system.
