Green-fruited Solanum habrochaites lacks fruit-specific carotenogenesis due to metabolic and structural blocks

Journal of Experimental Botany, 2017
The green-fruited Solanum habrochaites encodes a functional phytoene synthase 1 but fails to accumulate lycopene due to metabolic and structural blocks in chromoplast formation and carotenoid storage.

Regulación de la carotenogenesis en Phycomyces

, 1975
Esta Tesis estudia la regulación de la síntesis de carotenoides en el hongo Phycomyces blakesleeanus. El tipo silvestre del hongo produce casi exclusivamente β-caroteno, pero las cantidades acumuladas dependen de factores ambientales, como la luz ...

Deciphering the genomic structure, function and evolution of carotenogenesis related phytoene synthases in grasses

BMC Genomics, 2012
Background Carotenoids are isoprenoid pigments, essential for photosynthesis and photoprotection in plants. The enzyme phytoene synthase (PSY) plays an essential role in mediating condensation of two geranylgeranyl diphosphate molecules, the first ...

A new regulatory mechanism controlling carotenogenesis in the fungus Mucor circinelloides as a target to generate β-carotene over-producing strains by genetic engineering

Microbial Cell Factories, 2016
BackgroundCarotenoids are natural pigments with antioxidant properties that have important functions in human physiology and must be supplied through the diet. They also have important industrial applications as food colourants, animal feed additives and

Comparative Analysis of Culture Conditions for the Optimization of Carotenoid Production in Several Strains of the Picoeukaryote Ostreococcus

Marine Drugs, 2018
Microalgae are promising sources for the sustainable production of compounds of interest for biotechnologies. Compared to higher plants, microalgae have a faster growth rate and can be grown in industrial photobioreactors. The microalgae biomass contains

Characterization of metabolic pathways of isoprenoids and beta-carotene formation during carotenogenesis in Dunaliella salina BC02

, 2006
La microalga verde Volvocal Dunaliella salina Teodoresco es la fuente natural más rica del carotenoide beta-caroteno. Existe una demanda de beta-caroteno como fuente de colorantes alimenticios, y también como suplemento dietarios para humanos y animales ...

Evolución de la red fotorreguladora en la bacteria "Myxococcus xanthus" y plasticidad en el modo de acción molecular de los fotorreceptores dependientes de la vitamina B12 [PDF]

, 2021
La luz señaliza diversos procesos biológicos, pero también puede causar daño celular. Myxococcus xanthus tiene dos rutas para detectar la luz y controlar la carotenogénesis, una respuesta fotoprotectora.

Regulation of carotenogenesis in the red yeast Xanthophyllomyces dendrorhous: the role of the transcriptional co-repressor complex Cyc8–Tup1 involved in catabolic repression

Microbial Cell Factories, 2016
BackgroundThe yeast Xanthophyllomyces dendrorhous produces carotenoids of commercial interest, including astaxanthin and β-carotene. Although carotenogenesis in this yeast and the expression profiles of the genes controlling this pathway are known, the ...

The Specialized Roles in Carotenogenesis and Apocarotenogenesis of the Phytoene Synthase Gene Family in Saffron

Frontiers in Plant Science, 2019
Crocus sativus stigmas are the main source of crocins, which are glucosylated apocarotenoids derived from zeaxanthin cleavage that give saffron its red color. Phytoene synthase (PSY) mediates the first committed step in carotenoid biosynthesis in plants.
