Arabidopsis FIBRILLIN6 regulates carotenoid biosynthesis by directly promoting phytoene synthase activity

2022
AbstractCarotenoids 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.

The y1 gene of maize codes for phytoene synthase.

Genetics, 1996
The cloned y1 locus of maize was sequenced and found to encode phytoene synthase. Different "wild-type" alleles of the locus were found to differ by the insertion of transposable elements in their promoter and polyA addition regions, and by the length of a CCA tandem repeat series, without any obvious effect on function of the gene.

Microsatellite polymorphism is likely involved in phytoene synthase activity in Citrus

Plant Cell, Tissue and Organ Culture (PCTOC), 2013
Carotenoid content is an important determinant of pigmentation in citrus fruit. Phytoene synthase (PSY) is an important enzyme in the carotenoid synthesis pathway. In the present study, two similar but non-identical sequences transcripts (CsPsy1a and CsPsy1b) were isolated from sweet orange, and accumulated at a high level throughout the period of ...

Enrichment of Carotenoids in Flaxseed by Introducing a Bacterial Phytoene Synthase Gene

2010
Carotenoids are well-known natural pigments, typically ranging from yellow to red. Carotenoids are industrially utilized as functional materials due to their strong antioxidant properties. Phytoene synthesis is known to be a rate-determining step in the entire carotenoid biosynthetic pathway in plants.

Phytoene synthase modulates seed longevity via β-carotene derived metabolites

Plant Physiology
Abstract Seed longevity, the seed’s ability to stay viable over time, is an important trait in agriculture that remains a fundamental topic in plant biology. Here, we discovered a function of carotenoid metabolites in prolonging seed lifespan.

Cloning, expression and characterisation of the cDNA encoding human hepatic squalene synthase, and its relationship to phytoene synthase

Gene, 1993
The reaction catalysed by squalene synthase (SQS) shows many similarities to that performed by another polyisoprene synthase, phytoene synthase (PhS). By identifying sequences conserved between yeast SQS (ySQS) and PhS, we have cloned a 2-kb cDNA (hSQS) encoding human SQS, a protein of 417 amino acids with a predicted M(r) of 48,041, which has only ...

White mutants of Chlamydomonas reinhardtii are defective in phytoene synthase.

Genetics, 2005
Carotenoids play an integral and essential role in photosynthesis and photoprotection in plants and algae. A collection of Chlamydomonas reinhardtii mutants lacking carotenoids was characterized for pigment and tocopherol (vitamin E) composition, growth phenotypes under different light conditions, and the molecular basis of their mutant phenotype.
