Stress hormone:
Abscisic acid is a plant hormone that is produced in response to stress conditions like drought, high salinity, and low temperature. It regulates various physiological processes in plants to help them cope with stress.
Functions of Abscisic acid:
1. Closing of stomata: Abscisic acid causes the stomata to close, reducing water loss through transpiration.
2. Seed dormancy: Abscisic acid maintains seed dormancy until the environmental conditions are favorable for germination.
3. Inhibition of shoot growth: Abscisic acid inhibits shoot growth, which helps plants conserve energy during stress conditions.
4. Induction of stress-responsive genes: Abscisic acid induces the expression of stress-responsive genes, which help plants cope with stress conditions.
Conclusion:
Thus, Abscisic acid is a stress hormone that plays a crucial role in helping plants cope with adverse environmental conditions.
