Mitosis Inhibitors Induce Massive Accumulation of Phytoene in the Microalga Dunaliella salina [PDF]
Phytoene is a colourless natural carotenoid that absorbs UV light and provides antioxidant and anti-inflammatory activities as well as protection against photodamage.

Hot Spots of Phytoene Desaturase from Rhodobacter sphaeroides Influencing the Desaturation of Phytoene [PDF]
Phytoene desaturase (CrtI, E.C. 1.3.99.31) shows variable desaturation activity, thereby introducing different numbers of conjugated double bonds (CDB) into the substrate phytoene. In particular, Rhodobacter sphaeroides CrtI is known to introduce additional 6 CDBs into the phytoene with 3 CDBs, generating neurosporene with 9 CDBs.

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

Bioactive Lipophilic Antioxidants (Carotenoids, Tocols, Retinol, and Coenzyme Q10) in Human and Animal Tissues: Development and Validation of a Rapid Extraction and Chromatographic Method for Nutrition and Health Studies [PDF]
A rapid and robust analytical method was validated for the simultaneous extraction and quantification of carotenoids and other lipophilic antioxidants (tocopherols, tocotrienols, retinol and coenzyme Q10) in human and animal tissues using a tandem RRLC ...

Phytoene and Phytoene-Rich Microalgae Extracts Extend Lifespan in C. elegans and Protect against Amyloid-β Toxicity in an Alzheimer’s Disease Model [PDF]
Phytoene is a colourless carotenoid widely available from dietary sources and a precursor for the synthesis of other carotenoids. Although present at high concentrations across different tissues, phytoene is largely viewed as not having physiological ...

Phytoene Accumulation in Sunflower Decreases the Transcript Levels of the Phytoene Synthase Gene
The non dormant-1 (nd-1) mutant of sunflower (Helianthus annuus L.) and fluridone-treated plants were used to investigate the effect of phytoene accumulation on the transcript levels of the phytoene synthase (Ha-PSY) gene. A deficiency at the gene coding for ζ-carotene desaturase (ZDS) characterises the nd-1 mutant, which displays an accumulation of ζ ...

Uncovering the Hidden Potential of Phytoene Production by the Fungus Blakeslea trispora
Phytoene is an uncommon linear carotene within the carotenoid group as it is colorless due to its short chromophore. Recent research constitutes a relatively new area which has emerged from phytoene’s importance as a major dietary carotenoid promoting ...

Protective effects of colorless carotenoid precursors against UV-induced lipid oxidation in liposomes compared to lycopene [PDF]
Consuming tomato-extracts can reduce the risk of developing chronic diseases. As lycopene supplementation alone had a weaker impact, the protective effect may be influenced by the colorless carotenoids phytoene and phytofluene.

Carotenoids are lipophilic pigments found in plants and algae, as well as some bacteria, archaea, and fungi that serve two functions—(1) as light harvesting molecules—primary carotenoids, and (2) as antioxidants, acting against reactive ...
