Characterization of C30 carotenoid and identification of its biosynthetic gene cluster in Methylobacterium extorquens AM1

Synthetic and Systems Biotechnology, 2023
Methylobacterium species, the representative bacteria distributed in phyllosphere region of plants, often synthesize carotenoids to resist harmful UV radiations.

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

Carotenoid Accumulation and the Expression of Carotenoid Metabolic Genes in Mango during Fruit Development and Ripening

Applied Sciences, 2021
Carotenoids are considered to be important components in mango fruits. However, there is a lack of understanding about the regulation of carotenoids in mango.

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.

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.

Oxidative physiology is weakly associated with pigmentation in birds

Ecology and Evolution, 2022
The mechanistic link between avian oxidative physiology and plumage coloration has attracted considerable attention in past decades. Hence, multiple proximal hypotheses were proposed to explain how oxidative state might covary with the production of ...

Fruit Colour and Novel Mechanisms of Genetic Regulation of Pigment Production in Tomato Fruits

Horticulturae, 2021
Fruit colour represents a genetic trait with ecological and nutritional value. Plants mainly use colour to attract animals and favour seed dispersion. Thus, in many species, fruit colour coevolved with frugivories and their preferences.

CHARACTERIZATION OF OIL AND CAKE FROM Spirogyra porticallis [PDF]

Biotechnologia Acta, 2021
Aim. Search of healthy and edible alternative oils from algae. Such oil provides many health benefits mainly because of docosahexaenoic acid (DHA) form of omega-3 fattyacids and some other micro nutrients in smaller amounts. Methods.
