NtDREB-1BL1 Enhances Carotenoid Biosynthesis by Regulating Phytoene Synthase in Nicotiana tabacum. [PDF]
Genes (Basel), 2022 As one of the most imperative antioxidants in higher plants, carotenoids serve as accessory pigments to harvest light for photosynthesis as well as photoprotectors for plants to adapt to high light stress. Phytoene synthase (PSY) is the entry enzyme and also the major rate-limiting enzyme in the carotenoid pathway.

Ubiquitination of phytoene synthase 1 precursor modulates carotenoid biosynthesis in tomato. [PDF]
Commun Biol, 2020 AbstractCarotenoids are natural pigments that are indispensable to plants and humans, whereas the regulation of carotenoid biosynthesis by post-translational modification remains elusive. Here, we show that a tomato E3 ubiquitin ligase, Plastid Protein Sensing RING E3 ligase 1 (PPSR1), is responsible for the regulation of carotenoid biosynthesis. PPSR1

Identification and Characterization Roles of Phytoene Synthase (PSY) Genes in Watermelon Development. [PDF]
Genes (Basel), 2022 Phytoene synthase (PSY) plays an essential role in carotenoid biosynthesis. In this study, three ClPSY genes were identified through the watermelon genome, and their full-length cDNA sequences were cloned. The deduced proteins of the three ClPSY genes were ranged from 355 to 421 amino acid residues.

Arabidopsis FIBRILLIN6 influences carotenoid biosynthesis by directly promoting phytoene synthase activity. [PDF]
Plant Physiol, 2023 Abstract Carotenoids are health-promoting plastidial isoprenoids with essential functions in plants as photoprotectants and photosynthetic pigments in chloroplasts. They also accumulate in specialized plastids named chromoplasts, providing color to non-photosynthetic tissues such as flower petals and ripe fruit.

Orange protein has a role in phytoene synthase stabilization in sweetpotato. [PDF]
Sci Rep, 2016 AbstractCarotenoids have essential roles in light-harvesting processes and protecting the photosynthetic machinery from photo-oxidative damage. Phytoene synthase (PSY) and Orange (Or) are key plant proteins for carotenoid biosynthesis and accumulation.

Functional analysis of the Phycomyces carRA gene encoding the enzymes phytoene synthase and lycopene cyclase. [PDF]
PLoS ONE, 2011 Phycomyces carRA gene encodes a protein with two domains. Domain R is characterized by red carR mutants that accumulate lycopene. Domain A is characterized by white carA mutants that do not accumulate significant amounts of carotenoids. The carRA-encoded

Stereoisomers of Colourless Carotenoids from the Marine Microalga Dunaliella salina
Molecules, 2020 Carotenoids comprise a diverse range of naturally occurring stereoisomers, which differ in their physico-chemical properties. Their biosynthesis begins with phytoene, which is a rarity among carotenoids because it is colourless.
