Abscisic acid Chemical Properties,Usage,Production
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.

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, is derived from the ability of a substance to promote abscission. Abscission is the natural detachment of leaves, branches, flowers, etc. from plants. Abscisic acid is a naturally occurring plant growth inhibitor, and is one of five major plant hormones. It carries out a number of important functions in the growth and development of plants. It is a key factor controlling stomatal movements, leaf senescence and bud and seed dormancy. Abscisic acid (ABA) is present in leaves, fruits and seeds, and is distributed throughout the plant body. The synthesis of ABA takes place mainly in chloroplasts. The rate of synthesis of ABA increases when the plant is under stress. Chemically, abscisic acid is a member of the terpenoid family.
Metabolic pathway
Plant growth regulators: promotion of maturation of the somatic embryo of white spruce Somatic embryo suspension cultures of white spruce containing (?+)-abscisic acid (ABA) metabolize (+?)- ABA almost completely to yield quantitatively phaseic acid with slight further transformation into dihydrophaseic acid within 7 days. (-)-ABA remains essentially unchanged under the same culture conditions, and when the cells are supplied with racemic (±)-ABA, only the (+?) enantiomer is metabolized.
