Mate choice for a male carotenoid-based ornament is linked to female dietary carotenoid intake and accumulation

open access: yesBMC Evolutionary Biology, 2012
Background The coevolution of male traits and female mate preferences has led to the elaboration and diversification of sexually selected traits; however the mechanisms that mediate trait-preference coevolution are largely unknown. Carotenoid acquisition

Revisiting the Baltimore–Bullock's Oriole hybrid zone reveals changing plumage colour in Bullock's Orioles

open access: yesRoyal Society Open Science, 2022
Hybrid zones are dynamic areas where populations of two or more interbreeding species may change through an influx of novel genetic material resulting from hybridization or selection on standing genetic variation.

Long-term strict raw food diet is associated with favourable plasma b-carotene and low plasma lycopene concentrations in Germans [PDF]

open access: yes, 2008
Dietary carotenoids are associated with a reduced risk of chronic diseases. Raw food diets are predominantly plant-based diets that are practised with the intention of preventing chronic diseases by virtue of their high content of beneficial nutritive ...

Phytoene Synthase: The Key Rate-Limiting Enzyme of Carotenoid Biosynthesis in Plants

open access: yesFrontiers in Plant Science, 2022
Phytoene synthase (PSY) catalyzes the first committed step in the carotenoid biosynthesis pathway and is a major rate-limiting enzyme of carotenogenesis.

Single-cell genomics based on Raman sorting reveals novel carotenoid-containing bacteria in the Red Sea [PDF]

open access: yes, 2016
Cell sorting coupled with single-cell genomics is a powerful tool to circumvent cultivation of microorganisms and reveal microbial ‘dark matter’. Single-cell Raman spectra (SCRSs) are label-free biochemical ‘fingerprints’ of individual cells, which can ...

Suppression of the Lycopene Cyclase Gene Causes Downregulation of Ascorbate Peroxidase Activity and Decreased Glutathione Pool Size, Leading to H2O2 Accumulation in Euglena gracilis

open access: yesFrontiers in Plant Science, 2021
Carotenoids are photosynthetic pigments and hydrophobic antioxidants that are necessary for the survival of photosynthetic organisms, including the microalga Euglena gracilis.

Metabolic fingerprinting to assess the impact of salinity on carotenoid content in developing tomato fruits [PDF]

open access: yes, 2016
As the presence of health-promoting substances has become a significant aspect of tomato fruit appreciation, this study investigated nutrient solution salinity as a tool to enhance carotenoid accumulation in cherry tomato fruit (Solanum lycopersicum L ...

Carotenoids and antioxidant enzymes as biomarkers of the impact of heavy metals in food chain [PDF]

open access: yes, 2016
Antioxidant enzymes (catalase and peroxidase) and carotenoids (lutein and â-carotene) are often used as biomarkers of metal contamination of water and agricultural soils.

The effect of Benzyladenin on reducing lipid peroxidation and carotenoids in Lilium oriental. cv belladonna [PDF]

open access: yesفیزیولوژی محیطی گیاهی, 2020
In order to evaluate the effect of pre-harvest spray with Benzyladenin (BA) on improving flower quality and delaying flower and leaf senescence in Lilium oriental, a study was carried out as a spilt plot factorial experiment where 5 levels of ...
