Abscisic Acid Signalling as a Target for Enhancing Drought Tolerance

Abscisic acid (ABA) is a vital hormone that confers abiotic stress tolerance in plants. The identification of PYR/PYL/RCAR proteins as bona fide ABA recep‐ tors and the subsequent elucidation of the structural mechanisms of the core ABA signalling pathway in recent years has provided new and powerful in‐ sights in targeting ABA signalling to enhance abiotic stress tolerance in agri‐ culture. Th...

Abscisic acid and sucrose regulate tomato and strawberry fruit ripening through the abscisic acid‐stress‐ripening transcription factor

Although great progress has been made towards understanding the role of abscisic acid (ABA) and sucrose in fruit ripening, the mechanisms underlying the ABA and sucrose signalling pathways remain elusive. In this study, transcription factor ABA-stress-ripening (ASR), which is involved in the transduction of ABA and sucrose signalling pathways, was isolated and analysed in the nonclimacteric fru...

Phosphonamide pyrabactin analogues as abscisic acid agonists.

A four step synthesis towards novel phosphonic pyrabactin analogues is presented. Via a stomatal closure and germination assay, the ability of the analogues to selectively induce the ABA-signaling pathway was demonstrated.

Biosynthesis of abscisic acid: incorporation of radioactivity from [2-14C]mevalonic acid by intact fruit.

A Quick Release Mechanism for Abscisic Acid

The hormone abscisic acid regulates development and survival of plants in response to environmental stresses. now demonstrate that in response to stress, abscisic acid can be made available via polymerization of a beta-glucosidase enzyme. This enzyme is reported to hydrolyze glucose-conjugated abscisic acid, thus increasing active abscisic acid concentrations.
