BMC Cell Biology, 2010 Background Vertebrate retinal photoreceptors are morphologically complex cells that have two apical regions, the inner segment and the outer segment. The outer segment is a modified cilium and is continuously regenerated throughout life.

An Ultrastructural and Immunohistochemical Analysis of the Outer Plexiform Layer of the Retina of the European Silver Eel (Anguilla anguilla L). [PDF]
PLoS ONE, 2016 Here we studied the ultrastructural organization of the outer retina of the European silver eel, a highly valued commercial fish species. The retina of the European eel has an organization very similar to most vertebrates.

Journal of Animal Ecology, EarlyView.Identifying the existence of ‘cryptic’ morphs is critical in animal ecology for providing a basis for accurately testing links between phenotype and environment. This study identifies the existence of previously undocumented variation in UV reflectance in Aegean wall lizards that likely has novel behavioural and evolutionary implications within this ...

Photoreceptor specific guanylate cyclases in vertebrate phototransduction
, 2002 Two membrane bound guanylate cyclases are expressed in vertebrate photoreceptor cells. They serve a key function in photoreceptor physiology as they synthesize the intracellular transmitter of photoexcitation guanosine 3',5'-cyclic monophosphate (cGMP ...

Photoreceptor specific splice variant of PROM1.
, 2022 A) Alignment of the photoreceptor-specific s8 isoform of PROM1 (RefSeq NP_001157057) to the ubiquitously expressed isoform s2 (RefSeq NP_001157049). The amino acids encoded by the photoreceptor specific exon 19 are shown in bold and shaded in gray.

An Anatomy of Fungal Eye: Fungal Photoreceptors and Signalling Mechanisms
Journal of Fungi, 2023 Organisms have developed different features to capture or sense sunlight. Vertebrates have evolved specialized organs (eyes) which contain a variety of photosensor cells that help them to see the light to aid orientation.

Ciliary photoreceptors in the cerebral eyes of a protostome larva
EvoDevo, 2011 Background Eyes in bilaterian metazoans have been described as being composed of either ciliary or rhabdomeric photoreceptors. Phylogenetic distribution, as well as distinct morphologies and characteristic deployment of different photopigments (ciliary ...

Mutation of vsx genes in zebrafish highlights the robustness of the retinal specification network
eLife, 2023 Genetic studies in human and mice have established a dual role for Vsx genes in retina development: an early function in progenitors’ specification, and a later requirement for bipolar-cells fate determination. Despite their conserved expression patterns,
