Abscisic Acid (ABA) is a key plant hormone, often called the "stress hormone." The (+)-Abscisic acid form, specifically (S)-(+)-ABA, is the natural, biologically active enantiomer found in plants.
What It Does (Primary Physiological Roles):
Stress Response: Its main role is to orchestrate a plant's response to environmental stresses, especially drought and salinity. It triggers stomatal closure in leaves to reduce water loss.
Seed Dormancy: Induces and maintains dormancy, preventing seeds from germinating under unfavorable conditions.
Bud Dormancy: Regulates dormancy in buds, enabling plants to survive winter.
Growth Inhibition: Generally acts as an antagonist to growth-promoting hormones (like auxins and gibberellins) under stress.
Other Functions: Involved in fruit ripening, leaf senescence, and response to pathogens.
Primary Uses & Applications:
Agricultural Biotechnology: Research focuses on modifying ABA pathways to develop drought-tolerant and stress-resilient crops.
Plant Tissue Culture: Used to induce somatic embryogenesis and maintain dormancy in cultured tissues.
Horticulture & Floriculture: Can be applied to manage stress during transplanting or to delay germination/growth commercially.
Scientific Research: A vital tool for studying plant stress signaling, dormancy, and water-use efficiency.
Note: A synthetic form of the active (S)-(+)-ABA (marketed as products like ProTone®) is used as a plant growth regulator to improve stress tolerance (e.g., in turfgrass, vineyards during transplant). It helps crops conserve water and survive temporary drought.
