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.

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

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
