The ubiquity of the apo-carotenoid abscisic acid (ABA) biosynthetic pathway elucidated in water-stressed, etiolated leaves of Phaseolus vulgaris (see A.D. Parry and R. Horgan, 1991, Physiol. Plant. 82, 320-326), has been difficult to establish. Light-grown leaves contain very high carotenoid: ABA

Violaxanthin is an abscisic Acid precursor in water-stressed dark-grown bean leaves.

Ingia / Ingia

The leaves of dark-grown bean (Phaseolus vulgaris L.) seedlings accumulate considerably lower quantities of xanthophylls and carotenes than do leaves of light-grown seedlings, but they synthesize at least comparable amounts of abscisic acid (ABA) and its metabolites when water stressed. We observed

Abscisic acid biosynthesis in roots : I. The identification of potential abscisic acid precursors, and other carotenoids.

The pathway of water-stress-induced abscisic acid (ABA) biosynthesis in etiolated and light-grown leaves has been elucidated (see A.D. Parry and R. Horgan, 1991, Physiol. Plant. 82, 320-326). Roots also have the ability to synthesise ABA in response to stress and it was therefore of interest to

The 9-cis-epoxycarotenoid cleavage reaction is the key regulatory step of abscisic acid biosynthesis in water-stressed bean.

Ingia / Ingia

Abscisic acid (ABA), a cleavage product of carotenoids, is involved in stress responses in plants. A well known response of plants to water stress is accumulation of ABA, which is caused by de novo synthesis. The limiting step of ABA biosynthesis in plants is presumably the cleavage of

The role of cis-carotenoids in abscisic acid biosynthesis.

Ingia / Ingia

Evidence has been obtained which is consistent with 9'-cis-neoxanthin being a major precursor of abscisic acid (ABA) in higher plants. A mild, rapid procedure was developed for the extraction and analysis of carotenoids from a range of tissues. Once purified the carotenoids were identified from
