Key properties

• Triggers stomatal closure via H₂O₂ transport
• Modulates TIP and PIP expression in germination
• Involved in pH and ion-dependent gating

^[1]

• Regulates seed development, dormancy, and stress response
• Influences fatty acid biosynthesis and accumulation

^[2]

• Antagonistic to ethylene in many processes (e.g., germination)
• Synergistic with ethylene in some contexts (e.g., coleoptile/root growth in rice)
• Regulates stomatal closure and stress tolerance

^[3]

• Regulates water loss and hydraulic conductance
• Enhances drought and salinity tolerance
• Coordinates with ROS signaling

^[1]

• Exogenous application to increase unsaturated fatty acid content in rapeseeds
• Molecular regulator of lipid metabolism during seed development

^[2]

• Mediates seed dormancy and germination inhibition
• Regulates drought and cold stress responses
• Interacts with ethylene signaling for root and coleoptile growth
