Specific Oxidative Cleavage of Carotenoids by VP14 of Maize

Schwartz, Steven H., Tan, Bao Cai, Gage, Douglas A., Zeevaart, Jan A. D., McCarty, Donald R.·1997·Science

Abstract

The plant growth regulator abscisic acid (ABA) is formed by the oxidative cleavage of an epoxy-carotenoid. The synthesis of other apocarotenoids, such as vitamin A in animals, may occur by a similar mechanism. In ABA biosynthesis, oxidative cleavage is the first committed reaction and is believed to be the key regulatory step. A new ABA-deficient mutant of maize has been identified and the corresponding gene, Vp14 , has been cloned. The recombinant VP14 protein catalyzes the cleavage of 9- cis -epoxy-carotenoids to form C 25 apo-aldehydes and xanthoxin, a precursor of ABA in higher plants.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
