In vitro study | In Arabidopsis cell cultures, Abscisic acid ((S)-(+)-Abscisic acid; 10 μM) simultaneously induces rapid alkalinization of the medium and plasma membrane depolarization. Abscisic acid (10 μM) increases Ca 2+ in cytosol of Arabidopsis cell suspension. Abscisic acid does not inhibit proton pumping directly but through an increase in cytosolic Ca 2+ . Lanthionine synthetase C-like 2 (LANCL2) is the natural receptor for Abscisic acid. Abscisic acid, both at the organism levels and in specific muscle cells ex vivo, increases both glucose and fatty acid metabolism in the mitochondria, increases glycogen synthesis, activates PI3K independently of insulin and promotes GLUT4 translocation to the cell membrane. |

Uses | Abscisic acid can stimulate the production of ethylene and promote fruit ripening. It inhibits the synthesis of DNA and protein. The physiological functions of abscisic acid are as follows: 1. Inhibit and promote growth. External application of abscisic acid concentration inhibits the growth of stems, hypocotyls, roots, coleoptiles or leaves. When the concentration is low, it promotes the rooting and hypocotyl elongation of isolated cucumber cotyledons, accelerates the reproduction of duckweed, and stimulates the development of parthenocarpy seeds. 2. Maintain bud and seed dormancy. Dormancy is related to the balance of gibberellin and abscisic acid in vivo. 3. Promote the shedding of fruits and leaves. 4. Promote stomatal closure. Abscisic acid can quickly close the stomata and is non-toxic to plants. It is a good anti-transpiration agent. A biological test method to test the concentration of abscisic acid is to float the outer leaf epidermis on the surface of various concentrations of abscisic acid solution. Within a certain range, the degree of stomatal opening and closing is inversely proportional to the concentration of abscisic acid. 5. Affect flowering. Under long-day conditions, abscisic acid can dormant the terminal buds of strawberries and blackberries and promote flowering. 6. Affect sexual differentiation. Gibberellin can make female hemp plants form male flowers. This effect can be reversed by abscisic acid, but abscisic acid cannot make male plants form female flowers. The natural isomer of abscisic acid. A plant growth regulator with a high affinity binding site for abscisic acid on the plasma membrane of faba faba cells. It is related to various physiological mechanisms such as seed dormancy, leaf shedding, stomatal movement and plant stress response. Through complex interactions with a variety of intracellular signaling systems, shedding isomers can regulate the expression of hundreds of plant genes. |
