(+)-cis,trans-Abscisic acid is a natural, active isomer of a plant hormone. The compound is involved in several roles including seed germination, stress response, embryogenesis, regulation of transpiration, and acts as a signal of reduced water availability. The most effects of ABA seem to be adaptive responses that promote water conservation in plants by reducing water losses and slowing growth. (+)-cis,trans-Abscisic acid is also a plant growth regulator which has high-affinity binding sites on plasmalemma of Vicia faba guard cells. ABA regulates gene expression of hundreds of plant genes through complex interactions of intracellular signaling systems. Seed dormancy, stomatal movement, leaf abscission and plant stress responses are several physiological mechanisms this compound is also involved in.

Natural isomer of the abscission accelerating plant hormone. For research use only. Not intended for diagnostic or therapeutic use. There are several effects of Abscisic acid: 1) Antitranspirant - Induces stomatal closure, decreasing transpiration to prevent water loss. 2) Inhibits fruit ripening. 3) Responsible for seed dormancy by inhibiting cell growth – inhibits seed germination. 4) Inhibits the synthesis of Kinetin nucleotide. 5) Downregulates enzymes needed for photosynthesis. 6) Acts on endodermis to prevent growth of roots when exposed to salty conditions.
