- Intervention effect Overexpression of SbASR4 in Arabidopsis reduced germination rate under salt stress.
- Intervention effect Overexpression of SbASR4 in Arabidopsis increased Na⁺ accumulation under salt stress.
- Intervention effect Overexpression of SbASR4 in Arabidopsis elevated H2O2 levels under salt stress.
- Intervention effect Silencing SbASR4 in sorghum markedly enhanced plant salt tolerance.
- Intervention effect SbASR4 was significantly downregulated under salt stress and natural water deficit in sorghum.
- Observation SbASR4 localized to the nucleus and plasma membrane in sorghum.
- Observation SbASR4 undergoes rapid degradation under salt stress.
- Intervention effect Silenced SbASR4 lines showed significant upregulation of SOS pathway-related genes, CAT, and SnRK1.1 under salt stress.
- Observation PP2C family gene expression changed in SbASR4-silenced sorghum lines under salt stress.
- Observation SbASR4 interacts with SbSOS2 in sorghum.
- Mechanism SbASR4 negatively regulates plant salt tolerance, potentially through the antioxidant system, ABA signaling pathway and Na⁺ homeostasis.
