Phytoene desaturation – “complex” vs. “simple”.

, 2012
Left, the plant/cyanobacterial system consisting of the two desaturases, phytoene desaturase (PDS) and ζ-carotene desaturase (ZDS). The pathway involves specific poly-cis-intermediates and results in the formation of 7,9,9′7′-tetra-cis-lycopene ...

Watermelon genotype‐independent transformation via direct organogenesis from the cotyledon base

Journal of Integrative Plant Biology, EarlyView.
Inducing adventitious buds from the base of watermelon cotyledon through direct organogenesis resulted in a watermelon genetic transformation system that overcomes regeneration barriers and genotype limitations.

A single gene for lycopene cyclase, phytoene synthase, and regulation of carotene biosynthesis in Phycomyces [PDF]

, 2001
Previous complementation and mapping of mutations that change the usual yellow color of the Zygomycete Phycomyces blakesleea- nus to white or red led to the definition of two structural genes for carotene biosynthesis.

Orchid genome evolution and trait innovation

Journal of Integrative Plant Biology, EarlyView.
Orchids became one of the world's most diverse plant groups through genome‐driven innovations, unique relationships with fungi and pollinators, and remarkable adaptability. This review explains the origins of orchids and the evolution of their distinctive life forms, flowers, and ecological strategies and highlights promising directions for future ...

Multiplicity of carotene patterns derives from competition between phytoene desaturase diversification and biological environments

, 2020
International audiencePhytoene desaturases catalyse from two to six desaturation reactions on phytoene, generating a large diversity of molecules that can then be cyclised and produce, depending on the organism, many different carotenoids. We constructed

Knocking Out Two Polyphenol Oxidase Genes Significantly Improves Recombinant Protein Purification in Nicotiana benthamiana

Plant Biotechnology Journal, EarlyView.
ABSTRACT Efficient purification remains a key technical challenge affecting the recovery efficiency of recombinant proteins in plant‐based systems. Complex metabolites, particularly polyphenols, often cause recombinant protein aggregation during purification.

Molecular cloning and expression in Escherichia coli of a cyanobacterial gene coding for phytoene synthase, a carotenoid biosynthesis enzyme

, 1992
The first committed step in the biosynthetic pathway of carotenoids in plants and algae is the conversion of geranylgeranyl pyrophosphate (GGPP) to prephytoene pyrophosphate (PPPP), which is converted to phytoene. We have cloned the gene pys that encodes

Comparison of the bioavailability and intestinal absorption sites of phytoene, phytofluene, lycopene and β-carotene [PDF]

, 2019
The mechanisms of main tomato carotenes (phytoene, phytofluene, lycopene and β-carotene) intestinal absorptionare still only partly understood. We thus compared carotene bioavailability in mice after gavage with carotene-rich oil-in-water emulsions.

Data_Sheet_1_Perturbations in the Carotenoid Biosynthesis Pathway in Tomato Fruit Reactivate the Leaf-Specific Phytoene Synthase 2.PDF

, 2022
The accumulation of the red carotenoid pigment lycopene in tomato (Solanum lycopersicum) fruit is achieved by increased carotenoid synthesis during ripening.

Assessment of carotenoid concentrations in red peppers (Capsicum annuum) under domestic refrigeration for three weeks as determined by HPLC-DAD

Food Chemistry: X, 2020
Red peppers (Capsicum annuum) are rich in carotenoids and are widely grown and consumed all over the world. Today’s consumption patterns are characterized by periodical purchases of food and longer food storage periods, including raw fruits and ...
