Chemical biology of abscisic acid
Journal of Plant Research, 2011Chemical biology is a discipline that utilizes chemicals to elucidate biological mechanisms and physiological functions. Various abscisic acid (ABA) derivatives have revealed the structural requirement for the perception by ABA receptors while biotin or caged derivatives of ABA have disclosed the localization of several ABA-binding proteins.

Helvetica Chimica Acta, 1976
AbstractA stereoselective synthesis of (±)‐abscisic acid (7) is described in which 2‐cis 3‐methylpent‐2‐en‐4‐yn‐1‐ol (2) is used to introduce the 2‐cis, 4‐trans geometry.

Journal of Plant Growth Regulation, 2005
The name ‘‘abscisic acid’’ (ABA) was proposed in 1968 for the sesquiterpenoid hormone previously known as ‘‘dormin’’ or ‘‘abscisin II,’’ which had been isolated from several higher plants (Addicott and others 1968). In early studies its functions appeared mostly negative inasmuch as ABA treatments reduced growth and inhibited germination.

Current Opinion in Cell Biology, 1995
The plant hormone abscisic acid (ABA) regulates the development and germination of seeds, as well as the adaptation of vegetative tissues to conditions of environmental stress. During the past year, considerable insights have been gained into the molecular nature of the complex signaling network that mediates the actions of ABA.

The classical plant hormone abscisic acid (ABA) was discovered over 50 years ago. ABA accumulates rapidly in plants in response to environmental stresses, such as drought, cold, or high salinity, and plays important roles in the adaptation to and survival of these stresses.

ABSCISIC ACID SIGNAL TRANSDUCTION
Annual Review of Plant Physiology and Plant Molecular Biology, 1998▪ Abstract The plant hormone abscisic acid (ABA) plays a major role in seed maturation and germination, as well as in adaptation to abiotic environmental stresses. ABA promotes stomatal closure by rapidly altering ion fluxes in guard cells. Other ABA actions involve modifications of gene expression, and the analysis of ABA-responsive promoters has ...

A radioimmunoassay for abscisic acid
Journal of Immunological Methods, 1984Abstract We have developed a radioimmunoassay for abscisic acid (ABA) in the 0.04 pmole to 48 pmoles range. It utilizes an iodinated derivative of (+) ABA-Gly Tyr as a tracer. A study of the cross-reactivities of structurally related compounds showed the specific binding of (+) BA, when the acid function was free, esterified or linked by amide ...

Abscisic acid in Penicillium italicum
Planta, 1969Abscisic acid (ABA) was found in Penicillium italicum Wehmer collected from the surface of infected oranges. After growth and subculturing 6 times on Czapek's medium, the fungus did not contain any detectable ABA.
