Evolutionary ecology of opsin gene sequence, expression and repertoire. [PDF]

open access: yes, 2017
Linking molecular evolution to biological function is a long-standing challenge in evolutionary biology. Some of the best examples of this involve opsins, the genes that encode the molecular basis of light reception.

Eggshell pigment composition covaries with phylogeny but not with life history or with nesting ecology traits of British passerines [PDF]

open access: yes, 2015
No single hypothesis is likely to explain the diversity in eggshell coloration and patterning across birds, suggesting that eggshell appearance is most likely to have evolved to fulfill many nonexclusive functions.

Production of bioactive β-carotene by the endophytic bacterium Citricoccus parietis AUCs with multiple in vitro biological potentials

open access: yesMicrobial Cell Factories, 2023
Background Although microalgae and plants are traditionally used for obtaining natural pigments, overexploitation and overharvesting threaten them. Bacteria represent a superior alternative for the production of pigments due to their ability to produce ...

Streptomyces-Derived Bioactive Pigments: Ecofriendly Source of Bioactive Compounds

open access: yesCoatings, 2022
Pigments have been used since historical times and are currently used in food, cosmetic, pharmaceutical, and other industries. One of the main sources of natural pigments are plants and insects; however, microorganisms are of great interest due to their ...

Fundamental Molecules of Life are Pigments which Arose and Evolved to Dissipate the Solar Spectrum

open access: yes, 2014
The driving force behind the origin and evolution of life has been the thermodynamic imperative of increasing the entropy production of the biosphere through increasing the global solar photon dissipation rate.

Dietary blue pigments derived from genipin, attenuate inflammation by inhibiting LPS-induced iNOS and COX-2 expression via the NF-κB inactivation. [PDF]

open access: yesPLoS ONE, 2012
The edible blue pigments produced by gardenia fruits have been used as value-added colorants for foods in East Asia for 20 years. However, the biological activity of the blue pigments derived from genipin has not been reported.The anti-inflammatory ...

The retina visual cycle is driven by cis retinol oxidation in the outer segments of cones [PDF]

open access: yes, 2017
Vertebrate rod and cone photoreceptors require continuous supply of chromophore for regenerating their visual pigments after photoactivation. Cones, which mediate our daytime vision, demand a particularly rapid supply of 11-cis retinal chromophore in ...
