Plant carotenoid cleavage oxygenases and their apocarotenoid products
Abstract
The oxidative cleavage of carotenoids leads to the production of apocarotenoids and is catalyzed by a family of carotenoid cleavage dioxygenases (CCDs). CCDs often exhibit substrate promiscuity, which probably contributes to the diversity of apocarotenoids found in nature. Biologically and commercially important apocarotenoids include the phytohormone abscisic acid, the visual and signaling molecules retinal and retinoic acid, and the aromatic volatile beta-ionone. Unexpected properties associated with the CCD catalytic products emphasize their role in many aspects of plant growth and development. For instance, CCD7 and CCD8 produce a novel, graft-transmissible hormone that controls axillary shoot growth in plants. Here, CCDs are discussed according to their roles in the biosynthesis of these products. Recent studies regarding their mechanism of action are also addressed.

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.
