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.

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

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.

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.

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.

Mouse models in which hypoxia can be genetically triggered in retinal pigmented epithelial cells show that hypoxia-induced metabolic stress alone can lead to photoreceptor atrophy/dysfunction.

Tuning of BiP activity by Fic-mediated AMPylation is required for Drosophila photoreceptor plasticity and attenuation of the unfolded protein response.
