The multidimensional regulation roles and mechanisms of calcium in fruit quality
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...

Carotenogenesis Is Regulated by 5′UTR-Mediated Translation of Phytoene Synthase Splice Variants [PDF]
Phytoene synthase (PSY) catalyzes the highly regulated, frequently rate-limiting synthesis of the first biosynthetically formed carotene. While PSY constitutes a small gene family in most plant taxa, the Brassicaceae, including Arabidopsis (Arabidopsis thaliana), predominantly possess a single PSY gene.

Structural characterization of highly glucosylated crocins and regulation of their biosynthesis during flower development in Crocus [PDF]
Crocin biosynthesis in Crocus has been proposed to proceed through a zeaxanthin cleavage pathway catalyzed by carotenoid cleavage dioxygenase 2 (CCD2), and followed by glucosylation reactions catalyzed by CsGT2 (UGT74AD1).

Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites

Carotenoids are the main pigments in watermelon (Citrullus lanatus L.) fruit and contribute to its aesthetic and nutritional value. Phytoene synthase (PSY) is reported to be the first rate-limiting enzyme in carotenogenesis and controls the carotenoid ...

Pro‐Vitamin A Biofortified Cavendish Banana: Trait Stability in the Field
ABSTRACT Vitamin A deficiency (VAD), a major global health concern, has driven efforts to develop staple crops with enhanced pro‐vitamin A (pVA) content. Delivering meaningful nutritional benefits, however, requires technologies that maintain elevated carotenoid levels under field conditions. Previous proof‐of‐concept work demonstrated that pVA content

Seed‐specific overexpression of phytoene synthase: increase in carotenoids and other metabolic effects [PDF]
SummaryA bacterial phytoene synthase (crtB) gene was overexpressed in a seed‐specific manner and the protein product targeted to the plastid in Brassica napus (canola). The resultant embryos from these transgenic plants were visibly orange and the mature seed contained up to a 50‐fold increase in carotenoids. The predominant carotenoids accumulating in

A comprehensive review on the colorless carotenoids phytoene and phytofluene [PDF]
Carotenoids and their derivatives are versatile isoprenoids involved in many varied actions, hence their importance in the agri-food industry, nutrition, health and other fields.

ABSTRACT The development of dual‐target inhibitors represents a cost‐effective strategy for integrated pest management. Here, we report the first dual‐target inhibitors designed against the evolutionarily conserved domain of phytoene synthase (PSY), a key enzyme in carotenoid biosynthesis.
