Differential Contribution of the First Two Enzymes of the MEP Pathway to the Supply of Metabolic Precursors for Carotenoid and Chlorophyll Biosynthesis in Carrot (Daucus carota)
TL;DR: A central role for DXS on modulating the production of MEP-derived precursors to synthesize carotenoids and chlorophylls in carrot is supported, confirming the pivotal relevance of this enzyme to engineer healthier, carotanoid-enriched products.
Unraveling the induction of phytoene synthase 2 expression by salt stress and abscisic acid in Daucus carota.

TL;DR: ABA increased during salt stress triggers binding of AREB/ABFs to DcPSY2 promoter, boosting carotenoid and ABA levels as a positive feedback mechanism.
Increased Nicotiana tabacum fitness through positive regulation of carotenoid, gibberellin and chlorophyll pathways promoted by Daucus carota lycopene β-cyclase (Dclcyb1) expression
Juan Moreno,Ariel Cerda,Kevin Simpson,Isabel López-Díaz,Esther Carrera,Michael Handford,Claudia Stange +6 more
TL;DR: The expression of Dclcyb1 in tobacco induces a positive feedback on the isoprenoid, carotenoid, gibberellin and chlorophyll pathways leading to an enhancement in fitness, biomass, photosynthetic efficiency and carOTenoid/chlorophyll composition.
Carotenoid Biosynthesis in Daucus carota.
TL;DR: The current evidence on the biosynthesis of carotenoid in carrot roots in response to environmental cues that has contributed to the understanding of the mechanism that regulates the accumulation ofcarotenoids are discussed, as well as theCarotenogenic gene expression and root development in D. carota.

Carrot DcALFIN4 and DcALFIN7 Transcription Factors Boost Carotenoid Levels and Participate Differentially in Salt Stress Tolerance When Expressed in Arabidopsis thaliana and Actinidia deliciosa

TL;DR: In this paper , two putative genes with the molecular characteristics of ALs, DcAL4 and Dc7, were identified in the carrot transcriptome, which encode nuclear proteins that transactivate reporter genes and bind to the carrot DcPSY2 promoter in yeast.
