Image_1_Single opsin driven white noise ERGs in mice.JPEG

open access: yes, 2023
PurposeElectroretinograms elicited by photopigment isolating white noise stimuli (wnERGs) in mice were measured. The dependency of rod- and cone-opsin-driven wnERGs on mean luminance was studied.MethodsTemporal white noise stimuli (containing all ...

Divergence in cis-regulatory sequences surrounding the opsin gene arrays of African cichlid fishes

open access: yesBMC Evolutionary Biology, 2011
Background Divergence within cis-regulatory sequences may contribute to the adaptive evolution of gene expression, but functional alleles in these regions are difficult to identify without abundant genomic resources.

RT-qPCR reveals opsin gene upregulation associated with age and sex in guppies (Poecilia reticulata) - a species with color-based sexual selection and 11 visual-opsin genes

open access: yesBMC Evolutionary Biology, 2011
Background PCR-based surveys have shown that guppies (Poecilia reticulata) have an unusually large visual-opsin gene repertoire. This has led to speculation that opsin duplication and divergence has enhanced the evolution of elaborate male coloration ...

THE THERMAL STABILITY OF RHODOPSIN AND OPSIN [PDF]

open access: yesThe Journal of General Physiology, 1958
Rhodopsin, the red photosensitive pigment of rod vision, is composed of a specific cis isomer of retinene, neo-b (11-cis), joined as chromophore to a colorless protein, opsin. We have investigated the thermal denaturation of cattle rhodopsin and opsin in aqueous digitonin solution, and in isolated rod outer limbs.

Phylogeny of opsin genes in Lepidoptera based on maximum likelihood.

open access: yes, 2013
Values on the nodes are the nonparametric bootstrap proportions (MLBPs). Moths denoted in blue and butterflies in red. Branch-specific ω values are shown on nodes of the common ancestors. a) R opsin; b) B opsin; c) UV opsin.

Evolution of cichlid vision via trans-regulatory divergence

open access: yesBMC Evolutionary Biology, 2012
Background Phenotypic evolution may occur through mutations that affect either the structure or expression of protein-coding genes. Although the evolution of color vision has historically been attributed to structural mutations within the opsin genes ...

Multiple Pathways of Visual Adaptations for Water Column Usage in an Antarctic Adaptive Radiation

open access: yesEcology and Evolution
Evolutionary transitions in water column usage have played a major role in shaping ray‐finned fish diversity. However, the extent to which vision‐associated trait complexity and water column usage is coupled remains unclear.
