A Metagenomics Analysis on B-Carotene Synthesis in Neurospora Crassa

International Journal of Applied Sciences and Biotechnology, 2015
We have studied insilico on evolutionary uniqueness of phytoene synthase, which is one of the regulatory enzymes of ?-carotene synthesis in Neurospora crassa.  This study reveals multiple sequence alignments showed high sequences with similarity within a species of bacteria, fungi and higher plants.  This results designate interestingly between species

Total carotenoid content, a-carotene and b-carotene, of landrace pumpkins (Cucurbita moschata Duch): a preliminary study. [PDF]

, 2018
Landrace pumpkins occur in nature and their potential as source of pro-vitamin A may be investigated in order to be used in conventional plant breeding or biofortification programs, aiming to increase the total carotenoids and b-carotene contents.

Differential Regulation of the b,b‐carotene 15,15′‐monooxygenase (BCMO1) Expression by b‐carotene and Retinoic Acid in Human Pulmonary Alveolar Epithelial Cells

The FASEB Journal, 2006
Vitamin A and its retinoid derivatives are essential for normal differentiation of respiratory epithelium. BCMO1 is the key enzyme in metabolism of the provitamin A carotenoid b‐carotene to retinoic acid (RA). Recent evidence suggests RA, the biologically active form of vitamin A, may regulate its production via negative feedback of intestinal BCMO1 ...

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

FEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

Advanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...

D–A Type Perylene Micelles With Synergistic Charge/Energy Transfer for Dual‐Path ROS Generation and Enhanced Photocatalysis

Advanced Science, EarlyView.
Dual‐state activation of singlet and triplet excitons is achieved in perylene‐based nanomicelles via donor engineering. By synergistically pairing charge transfer with energy transfer pathways, while concurrently enabling pollutant pre‐enrichment, this strategy establishes spatial coupling between efficient ROS generation and rapid mineralization ...

Identification of an Allelic Variant of the CsOr Gene Controlling Fruit Endocarp Color in Cucumber (Cucumis sativus L.) Using Genotyping-By-Sequencing (GBS) and Whole-Genome Sequencing

Frontiers in Plant Science, 2021
The cucumber is a major vegetable crop around the world. Fruit flesh color is an important quality trait in cucumber and flesh color mainly depends on the relative content of β-carotene in the fruits.

Plasma concentrations of carotenoids and vitamin C are better correlated with dietary intake in normal weight than overweight and obese elderly subjects. [PDF]

, 2007
Carotenoid and vitamin C intakes, assessed by FFQ, have been positively associated with plasma concentrations in different populations. However, the influence of BMI on these associations has not been explored in detail.
