Biochemical Characterization of the aba2 and aba3 Mutants in Arabidopsis thaliana
TL;DR: The biochemical characterization of mutants at two new loci, aba2 and aba3, isolated in Arabidopsis thaliana, indicates that the aba 2 mutant is blocked in the conversion of xanthoxin to ABA-aldehyde and that aba 3 is impaired in the Conversion of A BA-aldehyde to A BA.

Role of abscisic acid in cadmium tolerance of rice (Oryza sativa L.) seedlings
Y. T. Hsu,Ching Huei Kao +1 more
TL;DR: Exogenous application of the ABA biosynthesis inhibitor, fluridone, reduced ABA accumulation, increased transpiration rate and Cd content, and decreased Cd tolerance of TNG67 seedlings was reversed by the application of ABA.
Journal ArticleDOI
Abscisic Acid biosynthesis and response
TL;DR: As a weak acid, ABA is mostly uncharged when present in the relatively acidic apoplastic compartment of plants and can easily enter cells across the plasma membrane, and the major control of ABA distribution among plant cell compartments follows the “anion trap” concept.

Genome-wide transcriptional analysis of grapevine berry ripening reveals a set of genes similarly modulated during three seasons and the occurrence of an oxidative burst at vèraison

TL;DR: The time-course gene expression analysis of grapevine berry development has identified the occurrence of two well distinct phases along the process, including a reprogramming stage of the cellular metabolism and the onset of a ripening-specialized metabolism responsible for the phenotypic traits of the ripe berry.

Salt stress response in tomato beyond the salinity tolerance threshold
TL;DR: Based on biomass production, water relations, leaf ions accumulation, leaf and root abscisic acid and stomatal conductance measurements, a specific EC value was identified at which a sharp increase of the shoot and root ABA levels coincided with a decreased sensitivity ofStomatal response to ABA.

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.

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.
