Identification of QTL and association of a phytoene synthase gene with endosperm colour in durum wheat

Theoretical and Applied Genetics, 2006
The yellow colour of durum wheat (Triticum turgidum L. var durum) semolina is due in part to the presence of carotenoid pigments found in the endosperm and is an important end-use quality trait. We hypothesized that variation in the genes coding for phytoene synthase (Psy), a critical enzyme in carotenoid biosynthesis, may partially explain the ...

Expression of an active phytoene synthase from Erwinia uredovora and biochemical properties of the enzyme

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1998
The crtB gene encoding phytoene synthase from the carotenogenic enterobacterium Erwinia uredovora was overexpressed to about 20% of the total cellular protein in Escherichia coli. Formation of the active phytoene synthase had the effect of suppressing the growth of the expressing strain.

From Prokaryotes to Eukaryotes: Insights into the Structure, Function, and Evolution of Phytoene Synthases

Journal of Agricultural and Food Chemistry
Phytoene synthase (PSY) catalyzes the committed and rate-limiting step in carotenoid biosynthesis by condensing two geranylgeranyl diphosphate molecules into 15-cis-phytoene. As the gateway enzyme, PSY directs metabolic flux toward diverse carotenoids, which functions as essential pigments, antioxidants, and provitamin A precursors in nutrition and ...

Regulation and activation of phytoene synthase, a key enzyme in carotenoid biosynthesis, during photomorphogenesis

Planta, 2000
During photomorphogenesis in higher plants, a coordinated increase occurs in the chlorophyll and carotenoid contents. The carotenoid level is under phytochrome control, as reflected by the light regulation of the mRNA level of phytoene synthase (PSY), the first enzyme in the carotenoid biosynthetic pathway. We investigated PSY protein levels, enzymatic

Cloning and characterization of a cDNA encoding phytoene synthase (PSY) in tea

2010
Carotenoids are an important group of precursors of volatile flavour compounds in tea and phytoene synthase (PSY) is a key enzyme during the biosynthesis pathway of carotenoids. A cDNA encoding PSYin tea shoot [Camellia sinensis (L.) O. Kuntze] was cloned and sequenced in the present study.
