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.

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.

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 ...

Planta, 1972
The (+)-abscisic acid content of pea shoots has been determined using gas-liquid chromatography. In both tall and dwarf cultivars no significant difference was observed between plants grown in the dark or under red light. Nor was the difference between the tall and dwarf cultivars themselves significant.

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.

Cuticular penetration of abscisic acid
Planta, 1972Penetration of 2-(14)C abscisic acid (ABA) through enzymatically isolated cuticles from tomato fruit and from the upper epidermis of apricot, pear and orange leaves was assessed. Penetration was linear with time, greater as the undissociated than the dissociated ion, and greater through dewaxed than non-dewaxed cuticles. Significantly less (3-6 times) (

The immunohistochemical technique enables us to visualize phytohormones, for example, abscisic acid (ABA) in plant cells. The distributions and levels of ABA would fluctuate dramatically in organs or tissues in response to environmental changes or developmental stages.

The dual effect of abscisic acid on stomata
New Phytologist, 2012Summary The classical view that the drought‐related hormone ABA simply acts locally at the guard cell level to induce stomatal closure is questioned by differences between isolated epidermis and intact leaves in stomatal response to several stimuli. We tested the hypothesis that ABA mediates, in addition to a local effect, a remote effect in planta ...
