Other claims from this paper (9)
- Intervention effect Short-term artificial cold treatment induced PaMYBS3 expression.
- Intervention effect Short-term artificial cold treatment improved cold resistance.
- Intervention effect Overexpression of PaMYBS3 in Arabidopsis promoted growth.
- Intervention effect Overexpression of PaMYBS3 in Arabidopsis reduced freezing tolerance.
- Intervention effect Domain-mutant and VIGS-silenced lines exhibited inhibited growth.
- Intervention effect Domain-mutant and VIGS-silenced lines exhibited enhanced cold adaptation.
- Mechanism PaMYBS3 enhances cold tolerance by modulating ROS balance, photosynthetic performance and osmotic regulators.
- Mechanism PaMYBS3 suppresses growth through downregulation of auxin- and sugar-related genes.
- Mechanism PaMYBS3 regulated cold-responsive pathways independently of the classical CBF/DREB1-COR module, suggesting a CBF-independent mechanism.
