Neoxanthin - Wikipedia
Neoxanthin is a carotenoid and xanthophyll that is an intermediate in the biosynthesis of abscisic acid in plants. It is a major xanthophyll in green leafy vegetables and has a role in protection against photooxidative stress.
Neoxanthin | Xanthophyll Carotenoid - MCE
Neoxanthin is a major xanthophyll carotenoid and a precursor of the plant hormone abscisic acid in dark green leafy vegetables. Neoxanthin is a potent antioxidant and light-harvesting pigment. Neoxanthin induces apoptosis and has anticancer actions.
Photoprotective Role of Neoxanthin in Plants and Algae - PMC
Neoxanthin is one of the key photosynthetic xanthophylls in plants and algae. In this work, structure, biosynthesis, and distribution of the molecule are reviewed, and the biological role of 9′-cis-neoxanthin (the most abundant neoxanthin isomer in chloroplasts) is described.

In all cases, expression of the algal VDL gene induced the accumulation of neoxanthin in parallel with a decrease in violaxanthin (Fig. 3A and table S3), further supporting the conclusion from the VDL-defective mutant of N. oceanica that VDL catalyzes the conversion of violaxanthin to neoxanthin in chromalveolates.
Characterization of the Role of the Neoxanthin Synthase Gene
2021年7月24日 · Neoxanthin synthase is a class of important carotenoid enzymes that participate in carotenoid biosynthesis, ABA synthesis, and photosynthesis [38,39]. Abscisic acid (ABA) is derived from the cleavage of 9-cis isomers of violaxanthin and neoxanthin and functions in embryogenesis and seed germination .
