Other claims from this paper (12)
- Intervention effect Salinity-alkalinity stress disrupted chlorophyll metabolism.
- Intervention effect Salinity-alkalinity stress hindered conversion of uroorphyrinogen III to protoporphyrin IX.
- Intervention effect Spermidine alleviated declines in total chlorophyll and chlorophyll a and b after four days of stress.
- Intervention effect With extended stress, spermidine reduced three chlorophyll precursors.
- Intervention effect With extended stress, spermidine increased protoporphyrin IX, Mg-protoporphyrin IX and protochlorophyllide.
- Observation The spermidine effect occurred earlier in Jinpengchaoguan than Zhongza No. 9.
- Intervention effect Spermidine alleviated stress-induced increases in malondialdehyde, superoxide generation and chlorophyllase activity.
- Intervention effect Spermidine alleviated stress-induced chlorophyllase gene expression.
- Intervention effect Spermidine alleviated stress-induced decreases in antioxidant enzyme activity and antioxidants.
- Intervention effect Spermidine alleviated decreased expression of the porphobilinogen deaminase gene.
- Intervention effect Spermidine stabilized chloroplast ultrastructure under stress.
- Mechanism The authors propose chloroplast structure, oxidative damage and chlorophyll and antioxidant regulation as mechanisms of spermidine protection.
