Application
(+)-Abscisic acid has been used:
- as a supplement for the germination of Arabidopsis thaliana seeds [1]
- as a component of buffered nodulation medium to check its effects on lateral root density (LRD) in leguminous and non-leguminous plants [2]
- as a standard to study its effects on root meristem defects in Medicago truncatula latd mutant [3]
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.

How does the storage temperature relate to shipping conditions?
1 answer-
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.
