Structures and functions of carotenoids bound to reaction centers from purple photosynthetic bacteria [PDF]

open access: yes, 2006
The photoprotective function of 15,15'-cis-carotenoids bound to the photosynthetic reaction centers (RCs) of purple bacteria has been studied using carotenoids reconstituted into carotenoidless RCs from Rhodobacter sphaeroides strain R26.1.

Carotenoid Pigment Accumulation in Horticultural Plants

open access: yesHorticultural Plant Journal, 2020
Carotenoids are a group of widely distributed natural pigments. They give many horticultural plants the bright red, orange, and yellow colors, as well as the aroma and flavor.

Fruit over sunbed : carotenoid skin coloration is found more attractive than melanin coloration [PDF]

open access: yes, 2015
Skin coloration appears to play a pivotal part in facial attractiveness. Skin yellowness contributes to an attractive appearance and is influenced both by dietary carotenoids and by melanin.

Structural and Functional Analysis of Nonheme Iron Enzymes BCMO-1 and BCMO-2 from Caenorhabditis elegans

open access: yesFrontiers in Molecular Biosciences, 2022
Carotenoid metabolism is critical for diverse physiological processes. The nematode Caenorhabditis elegans has two genes that are annotated as β-carotene 15,15′-monooxygenase (BCMO) and are 17 centimorgan apart on chromosome II, but the function of BCMO ...

Carotenoid triplet state formation in Rhodobacter sphaeroides R-26 reaction centers exchanged with modified bacteriochlorophyll pigments and reconstituted with spheroidene [PDF]

open access: yes, 1993
Triplet state electron paramagnetic resonance (EPR) experiments have been carried out at X-band on Rb. sphaeroides R-26 reaction centers that have been reconstituted with the carotenoid, spheroidene, and exchanged with 132-OH-Zn-bacteriochlorophyll a and

Methylotroph bacteria and cellular metabolite carotenoid alleviate ultraviolet radiation-driven abiotic stress in plants

open access: yesFrontiers in Microbiology, 2023
Increasing UV radiation in the atmosphere due to the depletion of ozone layer is emerging abiotic stress for agriculture. Although plants have evolved to adapt to UV radiation through different mechanisms, but the role of phyllosphere microorganisms in ...
