Over-expression of LeNCED1 in tomato (Solanum lycopersicum L.) with the rbcS3C promoter allows recovery of lines that accumulate very high levels of abscisic acid and exhibit severe phenotypes.
Swee Ang Tung,Rachel C. Smeeton,Charlotte A. White,Colin R. Black,Ian Taylor,Howard W. Hilton,Andrew J. Thompson +6 more
TL;DR: The rbcS3C promoter is reported, from a gene encoding the small subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), to drive LeNCED1 transgene expression in tomato in a light-responsive and circadian manner, and allows the generation of transgenic plants with much higher levels of ABA accumulation in leaves and sap.

Characterization of BspA, a major boiling-stable, water-stress-responsive protein in aspen (Populus tremula).
TL;DR: A novel 66 kDa boiling-stable protein (BspA) was identified in cultured shoots of aspen which was highly expressed in response to gradual water stress and cross-reacted with antibodies raised against a water-stress-responsive protein isolated from the African resurrection plant Craterostigma plantagineum Hochst.

Pea dehydrins: identification, characterisation and expression
TL;DR: A comparison of the pea dehydrin sequence with sequences from other species revealed conserved amino acid regions: an N-terminal DEYGNP and a lysine-rich block (KIKEKLPG), both of which are present in two copies.

Abscisic acid controls dormancy development and bulb formation in lily plantlets regenerated in vitro
TL;DR: The data indicate that the level of endogenous ABA and an unknown additional factor play major roles in the development of dormancy.
Journal ArticleDOI
The development of dormancy in bulblets of Lilium speciosum generated in vitro. 1. The effects of culture conditions.
TL;DR: Temperature had a strong effect on the induction of dormancy of bulblets generated on scale explants of Lilium speciosum Thunb.

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.
