Description

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.
