Phytoene synthase 2 in tomato fruits remains functional and contributes to abscisic acid formation
bioRxiv, 2021 In ripening tomato fruits, the leaf-specific carotenoids biosynthesis mediated by phytoene synthase 2 (PSY2) is replaced by a fruit-specific pathway by the expression of two chromoplast-specific genes: phytoene synthase 1 (PSY1) and lycopene-β-cyclase ...

, 2021 Phytoene and phytofluene are rarities among carotenoids as they are colourless, have a less rigid conformation and differ in their reactivity compared to other bioavailable carotenoids. Although they have been traditionally ignored, there is an expanding

A universal primer for isolation of fragments of a gene encoding phytoene desaturase for use in virus-induced gene silencing (VIGS) studies [PDF]
, 2010 We have been using Virus-Induced Gene Silencing (VIGS) to test the function of genes that are candidates for involvement in floral senescence. Although VIGS is a powerful tool for assaying the effects of gene silencing in plants, relatively few taxa have

Stereochemistry of phytoene biosynthesis by isolated chloroplasts [PDF]
Biochemical Journal, 1969 The incorporation of [2−14C,(5R)-5−3H1]MVA* and [2−14C,5−3H2]MVA into geranylgeraniol and phytoene by a preparation of ‘non-aqueous’ bean leaf chloroplasts has been studied. In the formation of phytoene from two molecules of geranylgeranyl pyrophosphate, the loss of hydrogen is stereospecific, the hydrogen atom lost from C-1 of each molecule of ...

On the structure and function of the phytoene desaturase CRTI from Pantoea ananatis, a membrane-peripheral and FAD-dependent oxidase/isomerase. [PDF]
PLoS ONE, 2012 CRTI-type phytoene desaturases prevailing in bacteria and fungi can form lycopene directly from phytoene while plants employ two distinct desaturases and two cis-tans isomerases for the same purpose. This property renders CRTI a valuable gene to engineer
