Resonance Energy Transfer and Purcell Effect in a Cu2O/Au Hybrid Optical Antenna

open access: yesAdvanced Photonics Research, EarlyView.
A Cu2O nanosphere mediates efficient (e.g., 70%) resonance energy transfer (RET) to a gold substrate. The RET damping constant derived from single‐particle scattering, ΓRET$\left(\Gamma\right)_{R E T}$, identifies interband transitions in Au. RET also occurs from an excited electron‐hole pair in Au to the Cu2O/Au hybrid resonator mode, followed by ...

Utilization of NIRS and Minolta Chromameter in selection for increased carotenoids content in cassava roots. [SP10-03] [PDF]

open access: yes, 2012
Significant progress has been made increasing carotenoids content in cassava roots. The information was used to test the usefulness of NIRs and the Minolta Chromameter in predicting carotenoids content (and other relevant traits). Quantification was made

The moss Bryum argenteum var. muticum Brid. is well adapted to cope with high light in continental Antarctica [PDF]

open access: yes, 2012
The net photosynthetic rate (NP), chlorophyll fluorescence, carotenoid content and chlorophyll content of the cosmopolitan moss Bryum argenteum were measured in the field at Botany Bay, southern Victoria Land, continental Antarctica (77°S).

An Allele of Glutamate Formiminotransferase Triggers 5‐Methyl‐Tetrahydrofolate‐to‐MeFox Conversion and Facilitates Folate Biofortification in Maize

open access: yesAdvanced Science, EarlyView.
This work demonstrates the distinct roles of the glutamate formiminotransferase (GFT) enzyme in plants. The GFT triggers the conversion of 5‐methyl‐tetrahydrofolate to MeFox in plants, a process distinct from its role as a formiminotransferase in mammals.

Content of fatty acids, vitamin E and carotenoids in milk and herbage as affected by sward composition and period of grazing [PDF]

open access: yes, 2011
The quality of organic milk is affected by feed composition, and especially the high use of legumes has been identified as the reason for high levels of polyunsaturated fatty acids, carotenoids and tocopherols in organic milk. Four different pastures

CAROTENOIDS IN FOODS

open access: yesInternational Conference on Technics, Technologies and Education, 2018
Carotenoids are pigments giving the yellow, orange and red colours to the fruits, vegetables, as well as products manufacturing from them. They belong to bio-active compound, being of special interest for the food scientists, nutritionists and food industry due to its positive effect on human health. They function as secondary antioxidants in the food,

A Study on the Cell Layer Patterns of a Citrus Periclinal Chimera Reveals β‐Cryptoxanthin Regulation in Citrus Fruits

open access: yesAdvanced Science, EarlyView.
Researchers have identified a citrus chimera with distinctive tissue origins and carotenoid profiles. It is discovered that fruit tissues develop from all three cell layers but in different proportions. A key transcription factor, MYB107, regulates β‐cryptoxanthin production by directly activating carotenoid biosynthesis genes, explaining why some ...

A C35 Carotenoid Biosynthetic Pathway [PDF]

open access: yes, 2003
Upon coexpression with Erwinia geranylgeranyldiphosphate (GGDP) synthase in Escherichia coli, C30 carotenoid synthase CrtM from Staphylococcus aureus produces novel carotenoids with the asymmetrical C35 backbone.

Carotenoids Database: structures, chemical fingerprints and distribution among organisms

open access: yesDatabase J. Biol. Databases Curation, 2017
To promote understanding of how organisms are related via carotenoids, either evolutionarily or symbiotically, or in food chains through natural histories, we built the Carotenoids Database.
