For vision, insect and vertebrate eyes use rhabdomeric and ciliary photoreceptor cells, respectively. These cells show distinct architecture and transduce the light signal by different phototransductory cascades. In the marine rag-worm Platynereis, we find both cell types: rhabdomeric photoreceptor cells in the eyes and ciliary photoreceptor cells in the brain. The latter use a photopigment closely related to vertebrate rod and cone opsins. Comparative analysis indicates that both types of… Expand
Ciliary photoreceptors in the cerebral eyes of a protostome larva
TLDR
The presence of ciliary photoreceptor-based eyes in protostomes suggests that the transition between non-visual and visual functions of photoreceptors has been more evolutionarily labile than previously recognized, and that co-option of c auxiliary and rhabdomeric Photoreceptor cell types for directional light detection has occurred multiple times during animal evolution. Expand
Phototransduction and the Evolution of Photoreceptors
TLDR
It is suggested that microvillar photoreceptors became predominant in most invertebrate species because of their single-photon sensitivity, high temporal resolution, and large dynamic range, and that rods and a duplex retina provided primitive chordates and vertebrates with similar sensitivity and dynamicrange, but with a smaller expenditure of ATP.

Co-expression of xenopsin and rhabdomeric opsin in photoreceptors bearing microvilli and cilia
TLDR
It is proposed that frequent opsin gene loss had a large influence on the evolution, organization and function of brain and eye photoreceptor cells in bilaterian animals. Expand
Ciliary and rhabdomeric photoreceptor-cell circuits form a spectral depth gauge in marine zooplankton
Ciliary and rhabdomeric photoreceptor cells represent two main lines of photoreceptor evolution in animals. The two photoreceptor-cell types coexist in some animals, however how they functionallyExpand

Photoreceptor cells and eyes in Annelida.
TLDR
The diversity of cerebral and extracerebral photoreceptor cells and ocelli as well as corresponding organs devoid of shading pigment is reviewed in Annelida. Expand
The visual pigment xenopsin is widespread in protostome eyes and impacts the view on eye evolution
TLDR
This study provides clear evidence that xenopsin enters cilia in the eye of the larval bryozoan Tricellaria inopinata and triggers phototaxis, and proposes that Xenopsin may play an important role in many protostome eyes and provides new insights into the function, evolution, and possible plasticity of animal eye photoreceptor cells.

Extraocular, rod-like photoreceptors in a flatworm express xenopsin photopigment
TLDR
Cellular assays show Mc xenopsin forms a photopigment and couples to Gα i/o in response to light, and highlight the convergent enclosure of photosensitive cilia in flatworm phaosomes and jawed vertebrate rods. Expand
Extraocular, rod-like photoreceptors in a flatworm express xenopsin photopigment
TLDR
This work characterized xenopsin in a flatworm, Maritigrella crozieri, and found it expressed in ciliary cells of eyes in the larva, and in extraocular cells around the brain in the adult, revealing a novel type of opsin-expressing cell that, like jawed vertebrate rods, encloses the ciliary membrane within their own plasma membrane. Expand
The retinal mosaics of opsin expression in invertebrates and vertebrates
TLDR
Despite distinct evolutionary origins, as well as major differences in morphology and phototransduction machineries, there are significant similarities in the stepwise cell‐fate decisions that lead to terminally differentiated photoreceptors that express a particular opsin. Expand

TLDR
It is proposed that the retinal ganglion, amacrine and horizontal cells are evolutionary sister cell types that evolved from a common rhabdomeric photoreceptor cell precursor, the proto-eye. Expand
The Rx homeobox gene is essential for vertebrate eye development
TLDR
It is shown that a conserved vertebrate homeobox gene, Rx, is essential for normal eye development, and that its misexpression has profound effects on eye morphology. Expand
The fine structure of prostomial photoreceptors in Eulalia viridis (Polychaeta; Annelida)
TLDR
The discussion seeks to establish SMC as an important component of microvillar photoreceptors in polychaetes as part of the metabolism of photopigment in Eulalia viridis. Expand
Development of pigment-cup eyes in the polychaete Platynereis dumerilii and evolutionary conservation of larval eyes in Bilateria.
TLDR
Analysis of expression of conserved eye specification genes in the early development of larval and adult pigment-cup eyes in Platynereis dumerilii indicates that polychaete six1/2 expression outlines the entire visual system from early developmental stages onwards and ath-positive clusters generate the first photoreceptor cells to appear.

Diminished Pupillary Light Reflex at High Irradiances in Melanopsin-Knockout Mice
TLDR
It is reported that in mice with the melanopsin gene ablated, RGCs retrograde-labeled from the suprachiasmatic nuclei were no longer intrinsically photosensitive, although their number, morphology, and projections were unchanged. Expand
Nonvisual photoreceptors of the deep brain, pineal organs and retina.
TLDR
Experimental and molecular aspects are discussed, focusing on the histological and histochemical basis of the function of nonvisual photoreceptors, and a view about functional changes of these photoreCEPTors during pre- and postnatal development as well as about its possible evolution are offered.

The genetic sequence of retinal development in the ciliary margin of the Xenopus eye.
TLDR
A spatial ordering of gene expression is predicted that predicts a genetic hierarchy governing vertebrate retinogenesis, corroborating some of the relationships between genes predicted to act sequentially. Expand
Xrxl, a novel Xenopus homeobox gene expressed during eye and pineal gland development
TLDR
Analysis of Xrx1 expression in embryos subjected to various treatments, or microinjected with different dorsalizing agents (noggin, Xwnt-8), suggests that vertical inductive signals leading to head morphogenesis are required to activate X Rx1. Expand
The chicken RaxL gene plays a role in the initiation of photoreceptor differentiation
TLDR
It is proposed that RaxL plays a role in the initiation of differentiation, and also possibly commitment, of photoreceptor cells in the chicken retina. Expand
Stereotyped pathway selection by growth cones of early epiphysial neurons in the embryonic zebrafish.
TLDR
Observations support the notion that local guidance cues exist within the early scaffold of brain tracts, as the presence and selective retention of filopodia within other axonal pathways suggests that growth cones have access to these pathways but do not select them. Expand
