Characterization and functional analysis of phytoene synthase gene family in tobacco [PDF]

BMC Plant Biology, 2021
Background Carotenoids play important roles in photosynthesis, hormone signaling, and secondary metabolism. Phytoene synthase (PSY) catalyzes the first step of the carotenoid biosynthetic pathway.

Perturbations in the Carotenoid Biosynthesis Pathway in Tomato Fruit Reactivate the Leaf-Specific Phytoene Synthase 2 [PDF]

Frontiers in Plant Science, 2022
The accumulation of the red carotenoid pigment lycopene in tomato (Solanum lycopersicum) fruit is achieved by increased carotenoid synthesis during ripening.

Molecular evolution and diversification of phytoene synthase (PSY) gene family [PDF]

Genetics and Molecular Biology, 2022
Phytoene synthase (PSY) is a crucial enzyme required for carotenoid biosynthesis, encoded by a gene family conserved in carotenoid-producing organisms. This gene family is diversified in angiosperms through distinct duplication events.

Orange protein, phytoene synthase regulator, has protein disulfide reductase activity [PDF]

Plant Signaling & Behavior, 2022
Orange protein (OR) is known to interact with phytoene synthase (PSY) that commits the first step in carotenoid biosynthesis, and functions as a major post-transcriptional regulator on PSY. We here tried to reveal enzymatic characteristics of OR, that is,

Diversification of tobacco phytoene-synthase-encoding genes coordinates carotenoid flux, strigolactone biosynthesis, and cold responses [PDF]

Frontiers in Plant Science
Phytoene synthase plays important roles in the development, metabolism, and various stress tolerance in plants. In the current study, a total of five tobacco phytoene synthase members were identified and systemically analyzed from the latest genome ...

Functional Characterization of the First Bona Fide Phytoene Synthase in Red Algae from Pyropia yezoensis [PDF]

Marine Drugs
The formation of phytoene by condensing two geranylgeranyl diphosphate molecules catalyzed by phytoene synthase (PSY) is the first committed and rate-limiting step in carotenoid biosynthesis, which has been extensively investigated in bacteria, land ...

Phytoene Synthase: The Key Rate-Limiting Enzyme of Carotenoid Biosynthesis in Plants [PDF]

Frontiers in Plant Science, 2022
Phytoene synthase (PSY) catalyzes the first committed step in the carotenoid biosynthesis pathway and is a major rate-limiting enzyme of carotenogenesis.

The Carrot Phytoene Synthase 2 (DcPSY2) Promotes Salt Stress Tolerance through a Positive Regulation of Abscisic Acid and Abiotic-Related Genes in Nicotiana tabacum [PDF]

Plants, 2023
Background: Carotenoids, which are secondary metabolites derived from isoprenoids, play a crucial role in photo-protection and photosynthesis, and act as precursors for abscisic acid, a hormone that plays a significant role in plant abiotic stress ...

The Specialized Roles in Carotenogenesis and Apocarotenogenesis of the Phytoene Synthase Gene Family in Saffron [PDF]

Frontiers in Plant Science, 2019
Crocus sativus stigmas are the main source of crocins, which are glucosylated apocarotenoids derived from zeaxanthin cleavage that give saffron its red color. Phytoene synthase (PSY) mediates the first committed step in carotenoid biosynthesis in plants.

Bioconversion of carotenoids into high-value crocins using a marine sponge carotenoid cleavage dioxygenase. [PDF]

New Phytol
Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites
