The recently characterized opsin group of xenopsins is likely a major player in animal eye evolution and may have been present in an ancient, highly plastic eye photoreceptor cell type.

A quantitative analysis of the connectivity between photoreceptors and bipolar cells in the mouse retina based on electron microscopy data yields exceptions from established rules of outer retinal connectivity.

In a zooplankton larva, ciliary and rhabdomeric photoreceptor cells work antagonistically to form a spectral depth gauge.

A novel B12 containing photoreceptor is synthesized as two different isoforms that interact with the same transcription factor, with one isoform directing activation and the other promoting repression of photosystem synthesis.

Birds that see ultraviolet light tune the sensitivity of their short-wavelength photoreceptors with colored filters to maximize the number of colors they can see.

Binding site affinity and transcription factor levels are finely tuned in nature to regulate stochastic expression, setting the ratio of alternative photoreceptor fates and determining color preference.

The eye produces a protein that inhibits the growth of blood vessels in the deep retina, which includes the photoreceptor layer, and disruption of this process can lead to blindness.

Molecular insights to phytochrome activation and signal transduction over long distances enable the allosteric regulation of enzymatic effectors.

Heterogeneity in perceptual sensitivity of human cone-mediated vision across wavelength originates in the cone photoreceptors, where S cones exhibit distinct functional properties in comparison to L and M cones.

Correlating changes in structure and gene expression in cone photoreceptors of mice daily, between birth and eye opening, created a resource that supports research in photoreceptor function, development, transplantation and repair.
