Transcriptomic and targeted metabolomic insights into carotenoid-mediated color formation in sorghum grains [PDF]

Frontiers in Plant Science
IntroductionSorghum is a major staple crop in semi-arid regions; however, its generally low grain carotenoid content limits its potential contribution to alleviating vitamin A deficiency.

Overexpression of PSY1 increases fruit skin and flesh carotenoid content and reveals associated transcription factors in apple (Malus × domestica)

Frontiers in Plant Science, 2022
Knowledge of the transcriptional regulation of the carotenoid metabolic pathway is still emerging and here, we have misexpressed a key biosynthetic gene in apple to highlight potential transcriptional regulators of this pathway. We overexpressed phytoene

Phylogenetic and evolutionary patterns in microbial carotenoid biosynthesis are revealed by comparative genomics. [PDF]

PLoS ONE, 2010
BACKGROUND: Carotenoids are multifunctional, taxonomically widespread and biotechnologically important pigments. Their biosynthesis serves as a model system for understanding the evolution of secondary metabolism.

Comparative Assessment of Lignan, Tocopherol, Tocotrienol and Carotenoids in 40 Selected Varieties of Flaxseed (Linum usitatissimum L.)

Foods, 2023
Multiple varieties of flaxseeds have been identified in the world, yet the relationship between these varieties, their agronomic traits, and their seeds’ quality remains unclear. This study aimed to determine the level of lignan, vitamins and carotenoids

Bacterial Carotenoids. XLVI. C50-Carotenoids. 14. C50-Carotenoids from Arthrobacter glacialis. [PDF]

Acta Chemica Scandinavica, 1975
From the psychrophilic bacterium Arthrobacter glacialis have been isolated three C50-carotenoids with molecular formulae C50H72O2: the bicyclic decaprenoxanthin (1a, 7% of total carotenoids), the aliphatic bisanhydrobacterioruberin (2a, 10%) and the monocyclic A.g. 470 (3a, 83%).

Studies on the absorption of beta-carotene and the distribution of total carotenoid in human serum lipoproteins after oral administration*

Journal of Lipid Research, 1962
The carotenoid increment in human serum was measured after the oral administration of aqueous dispersions and lipid dispersions of β-carotene with different test meal regimens. β-carotene was readily absorbed in both forms.
