Endogenous Abscisic Acid Content Correlates with Photon Fluence Rate and Induced Leaf Morphology in Hippuris vulgaris.
TL;DR: A role for abscisic acid in the high light-induced heterophylly in H. vulgaris is supported and additional support is provided for the general hypothesis that absc isic acid regulates leaf development in heterophyllic aquatic plants.

The Physiological Role of Abscisic Acid in Eliciting Turion Morphogenesis
TL;DR: It is demonstrated that the exogenous concentration of ABA used to induce turions leads to tissue concentrations of A BA within the physiological range, as quantified by both enzyme-linked immunosorbent assay and high-performance liquid chromatography/gas chromatography-electron capture detection analysis.

Preparation of (±)-[1,2-13C2]Abscisic Acid for Use as a Stable and Pure Internal Standard
Tadao Asami,Katsuhiko Sekimata,Jing Ming Wang,Koichi Yoneyama,Yasutomo Takeuchi,Shigeo Yoshida +5 more
TL;DR: In this article, the Witting reaction of 1-hydroxy-4-keto-α-ionone with carbomethoxymethylenetriphenylphosphorane prepared from [1,2-13C2]bromoacetic acid followed by saponification of the product methyl [1.2]-ABA was used for GC/MS analysis.

Abscinazole-E2B, a practical and selective inhibitor of ABA 8′-hydroxylase CYP707A
Mariko Okazaki,M. Kittikorn,Kotomi Ueno,Masaharu Mizutani,Nobuhiro Hirai,Satoru Kondo,Toshiyuki Ohnishi,Yasushi Todoroki +7 more
TL;DR: The R-enantiomer of Abz-E2B was the more potent inhibitor of CYP707A, unlike UNI, whereas both enantiomers were markedly less effective than S-UNI in inhibiting CYP701A.

Movement of Abscisic Acid Across the Plasmalemma and the Tonoplast of Guard Cells of Valerianella locusta
M. Baier,W. Hartung +1 more
TL;DR: It is concluded that ABA transport across the guard cell tonoplast is catalyzed by a saturable uptake component, which is too low to explain the high vacuolar ABA concentration by trapping of ABA−, whereas the cytosol is sufficiently alkaline to act as an efficient anion trap.

Induction of dormancy during seed development by endogenous abscisic acid: studies on abscisic acid deficient genotypes of Arabidopsis thaliana (L.) Heynh.
TL;DR: Mutant lines of Arabidopsis thaliana (L.) Heynh, which are characterized by symptoms of withering and the absence of seed dormancy, showed much lower levels of endogenous abscisic acid (ABA) in developing seeds and fruits than the wild type, and it seems that limited access to water is the primary trigger for the developmental arrest in these seeds.

Biochemistry and physiology of abscisic acid.
TL;DR: This chapter discusses the localization and regulation of ABA, the mode of action of A.lJA, and the role of stomatal complexes and A.spoTf in this synthesis.

Role of ABA in Maturation of Rapeseed Embryos
TL;DR: Results are consistent with the hypothesis that in maturing rapeseeds, low water content rather than ABA prevents germination during the later stages of development.

High-affinity binding sites for abscisic acid on the plasmalemma of Vicia faba guard cells
Claudia Hornberg,Elmar W. Weiler +1 more
TL;DR: In this article, high affinity guard cell-specific ABA-binding proteins were found in the plasmalemma of the stomata of leaves with high density, and all characteristics examined, they bear the properties of ABA receptors.
Journal ArticleDOI
Rapeseed embryo development in culture on high osmoticum is similar to that in seeds.
TL;DR: Measurements of endogenous abscisic acid (ABA) levels by radioimmunoassay indicated that the osmotic effects on germination and gene expression were not mediated by elevated embryonic ABA, consistent with the hypothesis that ABA acts by inhibiting water uptake, which mechanically prevents germinating and affects gene expression in some unknown manner.
