Genetic basis of microbial carotenogenesis [PDF]

, 2010
The synthesis of carotenoids begins with the formation of a phytoene from geranylgeranyl pyrophosphate, a well conserved step in all carotenogenic organisms and catalyzed by a phytoene synthase, an enzyme encoded by the crtB(spy) genes.

Metabolic engineering of astaxanthin biosynthesis in maize endosperm and characterization of a prototype high oil hybrid [PDF]

, 2016
Maize was genetically engineered for the biosynthesis of the high value carotenoid astaxanthin in the kernel endosperm. Introduction of a β-carotene hydroxylase and a β-carotene ketolase into a white maize genetic background extended the carotenoid ...

Two Indel Variations in the Regulated Carotenoid Pigment Gene Hold the Key to the Interspecies Flower Colour Differentiation in Liriodendron Plants

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2260-2275, April 2026.
ABSTRACT Flower colour variation is pivotal for plant evolution, ecological adaptation, and pollinator attraction. In the Liriodendron genus, L. tulipifera features a distinct orange petal stripe which is absent in L. chinense, driven by differential carotenoid accumulation, yet the underlying genetic mechanism remains unclear.

Proteomic analysis identified proteins that are differentially expressed in the flavonoid and carotenoid biosynthetic pathways of Camellia Nitidissima flowers

BMC Plant Biology
Background Camellia nitidissima Chi is a popular ornamental plant because of its golden flowers, which contain flavonoids and carotenoids. To understand the regulatory mechanism of golden color formation, the metabolites of C.

Strigolactone Levels in Dicot Roots Are Determined by an Ancestral Symbiosis-Regulated Clade of the PHYTOENE SYNTHASE Gene Family

Frontiers in Plant Science, 2018
Strigolactones (SLs) are apocarotenoid phytohormones synthesized from carotenoid precursors. They are produced most abundantly in roots for exudation into the rhizosphere to cope with mineral nutrient starvation through support of root symbionts ...

Optimization of light spectrum and intensity to enhance growth and metabolite profiles in green and purple radish microgreens cultivated in a vertical farming system

Journal of the Science of Food and Agriculture, Volume 106, Issue 5, Page 3118-3129, 30 March 2026.
Abstract BACKGROUND Microgreens have emerged as a promising crop in vertical farming due to their high nutritional value and short growth cycles. Light spectrum and intensity are critical factors influencing biomass production and metabolic activity in plants, particularly in controlled environments such as vertical farming systems. This study aimed to
