Unique Temporal Expression of Triplicated Long-Wavelength Opsins in Developing Butterfly Eyes
Following gene duplication events, the expression patterns of the resulting gene copies can often diverge both spatially and temporally. Here we report on gene duplicates that are expressed in distinct but overlapping patterns, and which exhibit ...

Rapid adaptive evolution of colour vision in the threespine stickleback radiation. [PDF]
Vision is a sensory modality of fundamental importance for many animals, aiding in foraging, detection of predators and mate choice. Adaptation to local ambient light conditions is thought to be commonplace, and a match between spectral sensitivity and ...

The photosensitive molecule rhodopsin and its relatives consist of a protein moiety - an opsin - and a non-protein moiety - the chromophore retinal. Opsins, which are G-protein-coupled receptors (GPCRs), are found in animals, and more than a thousand have been identified so far.

Material Strategies for Stimulation and Recording in Neural Biocomputing Platforms
Material strategies enabling stimulation and recording are central to neural biocomputing systems. This review examines how electronic materials govern the encoding of inputs and decoding of outputs in living neural networks. Advances in electrical, optical, and multimodal interfaces highlight emerging design principles for biocomputing platforms ...

Extraocular, rod-like photoreceptors in a flatworm express xenopsin photopigment
Animals detect light using opsin photopigments. Xenopsin, a recently classified subtype of opsin, challenges our views on opsin and photoreceptor evolution.

Background Opsins are the primary proteins responsible for light detection in animals. Cnidarians (jellyfish, sea anemones, corals) have diverse visual systems that have evolved in parallel with bilaterians (squid, flies, fish) for hundreds of millions ...

The Cone Dysfunction Syndromes [PDF]
The cone dysfunction syndromes are a heterogeneous group of inherited, predominantly stationary retinal disorders characterised by reduced central vision, and varying degrees of colour vision abnormalities, nystagmus and photophobia.

Wild-type opsin does not aggregate with a misfolded opsin mutant
Rhodopsin is the light receptor in photoreceptor cells that plays a central role in phototransduction and photoreceptor cell health. Mutations in rhodopsin are the leading cause of autosomal dominant retinitis pigmentosa (adRP), a retinal degenerative disease. A majority of mutations in rhodopsin cause misfolding and aggregation of the apoprotein opsin.

Loss, persistence and reversal of phenotypic traits
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...
