Plant Growth Regulators in Citriculture: Factors Regulating Endogenous Levels in Citrus Tissues
TL;DR: A comprehensive overview of published information on endogenous levels of the five classes of plant growth substances plus polyamines and other endogenous substances that appear to have a role in regulating citrus growth and development is provided.

Responsiveness to abscisic acid of embryos of dormant oat (Avena sativa) seeds : involvement of ABA-inducible proteins
TL;DR: The general results suggest that the presence of ABA was necessary to maintain the synthesis of A BA-inducible proteins; on removal of Aba their synthesis ceased.

Formation of Norisoprenoid Flavor Compounds in Carrot (Daucus carota L.) Roots: Characterization of a Cyclic-Specific Carotenoid Cleavage Dioxygenase 1 Gene
Mosaab Yahyaa,Einat Bar,Neeraj Kumar Dubey,Ayala Meir,Rachel Davidovich-Rikanati,Joseph Hirschberg,Radi Aly,Dorothea Tholl,Philipp W. Simon,Yaakov Tadmor,Efraim Lewinsohn,Mwafaq Ibdah +11 more
TL;DR: A role for DcCCD1 is suggested in carrot flavor biosynthesis after a cDNA encoding a protein with carotenoid cleavage dioxygenase activity was identified in carrot and was overexpressed in Escherichia coli strains previously engineered to produce differentCarotenoids.

Nitrate does not compete with abscisic acid as a substrate of AtNPF4.6/NRT1.2/AIT1 in Arabidopsis.
TL;DR: The results do not support the idea of a physiological linkage between nitrate and ABA signals through AtNPF4.6, as an abscisic acid (ABA) transporter, AIT1.2.

Timing of kernel development in water-stressed maize: water potentials and abscisic acid concentrations.
Eric S. Ober,Tim L. Setter +1 more
TL;DR: It is plausible that the amount of ABA accumulated in kernels at the early stage may depend on the water status of maternal tissues, and imposition of water stress during this period of grain development would increase endogenous ABA concentration in kernel tissues, which may hasten the onset of storage product accumulation.

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.
