Phytochemistry, 1972
Abstract Samples of phytoene (7,8,11,12,7′,8′,11′,12′-octahydro-ψ,ψ-carotene) isolated from higher plant sources, from Neurospora crassa and strains of Phycomyces blakesleeanus and from diphenylamine-inhibited cultures of Rhodospirillum rubrum have been examined by a number of physical methods. All the organisms accumulate predominantly 15- cis

Envelope membranes of spinach chloroplasts contain appreciable activities of the carotenogenic enzymes phytoene synthase (formation of phytoene by condensation of two molecules geranylgeranyl pyrophosphate) and phytoene dehydrogenase (formation of lycopene from phytoene), plus a phosphatase activity.

Momordica charantia, a tropical plant, produces a fruit that has a β-carotene concentration five times higher than that of carrot. To elucidate the molecular basis of β-carotene accumulation in M. charantia, the gene expression levels of phytoene synthase (McPSY) and phytoene desaturase (McPDS) were determined.

The aim of this work was to study the accumulation of phytoene in Dunaliella salina V-101 by down-regulating its phytoene desaturase (PDS) gene expression using RNA interference and Antisense technology. RNAi and antisense constructs were introduced into the Dunaliella cells by Agrobacterium-mediated transformation.

Carotenoids have been recognized as chemopreventive agents against human diseases, such as cancer and cardiovascular disease. Mammalians utilize carotenoids supplied from their food since they are unable to perform the de novo synthesis of carotenoids.

Abstract The configuration of natural phytoene is established as 15,15′ cis -7,8,7′,8′,11,12, 11′,12′-octahydrolycopene through ultraviolet, infrared, and nuclear magnetic resonance spectral analyses and through catalytic isomerization with iodine.

Abstract Phytoene, a noncrystalline, colorless polyene isolated from tomatoes and carrot oil has been shown to have an acyclic isoprenic structure, and its perhydro derivative (perhydrophytoene) has been shown to be identical with perhydrolycopene. According to its physical and chemical properties and to the isolation of acetone, levulinic aldehyde ...

Phytoene production in Phycomyces
Archives of Biochemistry and Biophysics, 1957Summary The effects of streptomycin and methylheptenone on phytoene production in Phycomyces blakesleeanus have been studied. It is shown that methylheptenone acts as a powerful stimulant of phytoene production. The magnitude of the accumulation is comparable with that of β -caro-tene by β -ionone.
