Abscisic Acid Function In Plants Abstract. abscisic acid (aba) is an important phytohormone regulating plant growth, development, and stress responses. it has an essential role in multiple physiological processes of plants, such as stomatal closure, cuticular wax accumulation, leaf senescence, bud dormancy, seed germination, osmotic regulation, and growth inhibition among many. Abscisic acid (aba or abscisin ii [5]) is a plant hormone. aba functions in many plant developmental processes, including seed and bud dormancy , the control of organ size and stomatal closure. it is especially important for plants in the response to environmental stresses , including drought , soil salinity , cold tolerance, freezing tolerance.
Role Of Abscisic Acid Aba In Plant Development And Stress Response Abscisic acid (aba), a stress hormone in plants and animals 2 cis, 4 trans abscisic acid (aba) is a 15 carbon weak acid (pka 4.8) terpenoid hormone ( figure 1 ) that regulates several pivotal physiological functions in plants, mainly involved in the response to abiotic and biotic stress (water and nutrient availability, uv irradiation; pathogen. Abscisic acid is a small sesquiterpene molecule with many crucial functions in plant phenological and developmental processes, including seed dormancy and development, vegetative growth, flowering, stomatal movement, lipid and storage protein synthesis, and leaf senescence (chen et al., 2020). 16.5a: abscisic acid (aba) unlike animals, plants cannot flee from potentially harmful conditions like drought, freezing, exposure to salt water or salinated soil. they must adapt or die. the plant hormone abscisic acid (aba) is the major player in mediating the adaptation of the plant to stress. here are a few examples. Abscisic acid (aba) is an important phytohormone regulating plant growth, development and stress responses. it has an essential role in multiple physiological processes of plants, such as stomatal closure, cuticular wax accumulation, leaf senescence, bud dormancy, seed germination, osmotic regulation and growth inhibition among many others.

Gain of function and loss of function phenotypes of the protein phosphatase 2c hab1 reveal its role as a negative regulator of abscisic acid signalling. plant j 2004; 37 : 354–69. Abscisic acid (aba) is a vital hormone that regulates plant growth, leaf abscission, seed and bud dormancy, and stress responses 1,2,3.a central question in the investigation of aba signaling is.
