Application

(+)-Abscisic acid has been used:

as a supplement for the germination of Arabidopsis thaliana seeds
as a component of buffered nodulation medium to check its effects on lateral root density (LRD) in leguminous and non-leguminous plants
as a standard to study its effects on root meristem defects in Medicago truncatula latd mutant

Biochem/physiol Actions

Plant hormone and growth regulator that is involved in several physiological mechanisms including seed dormancy, leaf abscission, stomatal movement, and plant stress responses. Through complex interactions with several intracellular signaling systems, it can regulate the expression of hundreds of plant genes.

Other Notes

Natural isomer of the abscission-accelerating plant hormone.

Malbec grape (Vitis vinifera L.) responses to the environment: Berry phenolics as influenced by solar UV-B, water deficit and sprayed abscisic acid.

Rodrigo Alonso et al.

Plant physiology and biochemistry : PPB, 109, 84-90 (2016-09-20)

High-altitude vineyards receive elevated solar ultraviolet-B (UV-B) levels so producing high quality berries for winemaking because of induction in the synthesis of phenolic compounds. Water deficit (D) after veraison, is a commonly used tool to regulate berry polyphenols concentration in

Structure and function of abscisic acid receptors.

Takuya Miyakawa et al.

Trends in plant science, 18(5), 259-266 (2012-12-26)

The phytohormone abscisic acid (ABA) plays a crucial role in adaptive responses to environmental stresses, such as drought and high salinity, as well as in plant development, such as seed maturation and dormancy. PYR/PYL/RCAR has been identified as a bona

Trait to gene analysis reveals that allelic variation in three genes determines seed vigour.

Karl Morris et al.

The New phytologist, 212(4), 964-976 (2016-07-20)

Predictable seedling establishment is essential for resource-efficient and cost-effective crop production; it is widely accepted as a critically important trait determining yield and profitability. Seed vigour is essential to this, but its genetic basis is not understood. We used natural

Ethylene responses in rice roots and coleoptiles are differentially regulated by a carotenoid isomerase-mediated abscisic acid pathway.

Cui-Cui Yin et al.

The Plant cell, 27(4), 1061-1081 (2015-04-05)

Ethylene and abscisic acid (ABA) act synergistically or antagonistically to regulate plant growth and development. ABA is derived from the carotenoid biosynthesis pathway. Here, we analyzed the interplay among ethylene, carotenoid biogenesis, and ABA in rice (Oryza sativa) using the

Abscisic acid rescues the root meristem defects of the Medicago truncatula latd mutant.

Yan Liang et al.

Developmental biology, 304(1), 297-307 (2007-01-24)

The LATD gene of the model legume, Medicago truncatula, is required for the normal function of three meristems, i.e. the primary root, lateral roots and nitrogen-fixing nodules. In latd mutants, primary root growth eventually arrests, resulting in a disorganized root
