TL;DR: It is shown that variation at the lycopene epsilon cyclase (lcyE) locus alters flux down α-carotene versus β-Carotene branches of the carotenoid pathway, which will enable developing-country breeders to more effectively produce maize grain with higher provitamin A levels.
Journal ArticleDOI
PSY3, a New Member of the Phytoene Synthase Gene Family Conserved in the Poaceae and Regulator of Abiotic Stress-Induced Root Carotenogenesis
TL;DR: The results suggest that PSY 3 expression influences root carotenogenesis and defines a potential bottleneck upstream of NCED; further examination of PSY3 in the grasses is of value for better understanding root-specific stress responses that impact plant yield.
Journal ArticleDOI
Mechanistic aspects of carotenoid biosynthesis
TL;DR: Carotenoids represent a large class of terpenoids characterized by an extensively conjugated polyene chain that carries out light independent functions in scavenging peroxyl radicals and preventing oxidative damage particularly against singlet oxygen (1O2).
Journal ArticleDOI
The Maize Phytoene Synthase Gene Family: Overlapping Roles for Carotenogenesis in Endosperm, Photomorphogenesis, and Thermal Stress Tolerance
TL;DR: Carotenoids are essential for photosynthesis and photoprotection; they also serve as precursors to signaling molecules that influence plant development and biotic/abiotic stress responses and are targets for metabolic breeding/engineering, particularly in the Poaceae family, which includes the major food crops.
Journal ArticleDOI
Metabolic engineering of carotenoid accumulation in Escherichia coli by modulation of the isoprenoid precursor pool with expression of deoxyxylulose phosphate synthase
TL;DR: Metabolic engineering of carbon flow from simple glucose metabolites to representatives of the largest class of natural products was demonstrated in this model system and rate-controlling enzymes encoded by the carotenogenic gene clusters are responsive to an increase in isoprenoid precursor pools.
