- Intervention effect Exogenous proline promotes seed germination and seedling growth of salt-stressed alfalfa.
- Intervention effect Proline application increases photosynthetic capacity and antioxidant enzyme activities under salt stress.
- Intervention effect Proline application decreases cell membrane damage and ROS accumulation under salt stress.
- Intervention effect Proline-treated plants maintain a better K+/Na+ ratio under salt stress.
- Intervention effect Proline treatment reduces Na+ accumulation under salt stress.
- Intervention effect Proline treatment increases K+ content under salt stress.
- Intervention effect Proline induces expression of the antioxidant genes Cu/Zn-SOD and APX under salt stress.
- Intervention effect Proline induces expression of the ion homeostasis genes SOS1, HKT1 and NHX1 under salt stress.
- Mechanism Proline metabolism is mainly regulated by OAT activity and transcription, according to the authors.
- Intervention effect Proline-treated plants show an increase in proline content under salt stress.
- Intervention effect OAT activity rather than P5CS activity is strongly increased under salt stress.
- Association The OAT gene expression level increases sharply compared with P5CS1 and P5CS2.
