Abscisic acid Usage And Synthesis
| Description | Abscisic Acid (ABA) is a phytohormone, a naturally occurring compound in plant. ABA is regarded as an inhibitor of plant growth and therefore usually used as a growth retardant in plant tissue culture. To date, ABA has been primarily used to promote the maturation of somatic embryos and the synthesis of storage reserves in embryos during maturation. ABA also acts as a controlling factor of germination and dormancy in somatic embryos and is generally used to induce somatic embryos into a quiescent state during plant tissue culture and synthetic seed studies. ABA stimulates the stomatal closure, thereby reducing transpirational water loss. Thus, it could be used as an anti-transpiration during the acclimatization of tissue culture-raised plants. |

| Chemical Properties | white to light yellow crystalline powder |
| Uses | abscission-accelerant; kinetin neucleotide synthesis inhibitor |
| Uses | Abscisic acid (ABA) is an isoprenoid plant hormone (phytohormone) synthesized in all parts of plants and involved in many plant developmental processes. ABA is involved in establishing dormancy and regulation of stress responses. ABA inhibits fruit ripening, seed germination, photosynthesis and kinetin biosynthesis. |
| Definition | ChEBI: 2-cis-abscisic acid is a member of the class of abscisic acids in which the double bond betweeen positions 2 and 3 has cis- (natural) geometry. It has a role as an abscisic acid receptor agonist. It is a conjugate acid of a 2-cis-abscisate. |
| Agricultural Uses | The name abscisic acid (ABA), a weak organic acid, isderived from the ability of a substance to promoteabscission. Abscission is the natural detachment ofleaves, branches, flowers, etc. from plants. Abscisic acidis a naturally occurring plant growth inhibitor, and is oneof five major plant hormones. It carries out a number ofimportant functions in the growth and development ofplants. It is a key factor controlling stomatal movements,leaf senescence and bud and seed dormancy.Abscisic acid (ABA) is present in leaves, fruits andseeds, and is distributed throughout the plant body. Thesynthesis of ABA takes place mainly in chloroplasts. Therate of synthesis of ABA increases when the plant is understress.Chemically, abscisic acid is a member of theterpenoid family. |
| Metabolic pathway | Plant growth regulators: promotion of maturationof the somatic embryo of white spruceSomatic embryo suspension cultures of white sprucecontaining (?+)-abscisic acid (ABA) metabolize (+?)-ABA almost completely to yield quantitatively phaseicacid with slight further transformation intodihydrophaseic acid within 7 days. (-)-ABA remainsessentially unchanged under the same cultureconditions, and when the cells are supplied withracemic (±)-ABA, only the (+?) enantiomer ismetabolized. |
