TL;DR
Differential incorporation into outer segments of red- and blue-vs green-sensitive cones was observed in fish retinae and into red but not green rods in the frog.
Abstract
The pattern of incorporation of3H-fucose into photoreceptor outer segments has been analysed by light and electron microscopic radioautography in twelve different species spanning the animal kingdom. This sugar is incorporated in a diffuse pattern into cone outer segments in all animals examined and is incorporated into a basal band in rod outer segments of certain species. Differential incorporation into outer segments of red- and blue-vs green-sensitive cones was observed in fish retinae and into red but not green rods in the frog. Diffuse labeling of frog pinealocyte outer segments was found, in agreement with previous observations of their cone-like structure and function.

The small size and number of cones in frog retinas probably makes the total relative contribution of cone pigment molecules too small for successful spectroscopic studies in extracts.

The photoreceptor cells of vertebrates, the rods and cones, detect and convey information and may thus be classified as neuronal cells, which suggests an evolution related to that of ependymal cells, as suggested by Krause.

Specific binding of anti-opsin antibodies indicates that opsin is localized in the disks of rod outer segments (ROS), as expected, and in the Golgi zone of the rod cell inner segments.

The evidence suggests that macrophages are involved in phagocytosis of degenerated outer segments of the pineal system from the adult frog and proposed photoreceptor activities and the possibility of secondary pineal functions, such as secretion, are discussed.

The intensity of binding of each lectin to the pigment epithelium plasma membrane was similar to its binding to the rod outer segment plasma membrane, and no differences were observed in the binding of ferritin-lectin complexes to rod outer segments from dark or light adapted frogs.

This study demonstrates that the type II cell of the adult rabbit has certain conelike morphologic features including a pale nucleus, complex synaptic pedicel, and multiple wrappings of the outer segment by microvilli of the pigment epithelium.

The visual receptor of the vertebrate retina is composed of several specialized compartments as shown in Figure 1, and the scierai part of the inner segment, the ellipsoid, contains numerous mitochondria and apparently constitutes a center of oxidative phosphorylation.

The evidence suggests that the major component of cone outer segments which becomes labeled with [3H]fucose is a protein with properties very similar to rod opsin.

The evidence suggests that fucose transfer does not involve a lipid carrier and that guanosine nucleotides including GMP uniformly inhibit the transfer, probably by direct competition with the GDP-fucose binding site.

A correlation exists between heavy labeling ofOSs maximally sensitive to red and blue light and lighter labeling of OSs with maximum sensitivity to green light, and this may reflect different carbohydrate compositions of the cone visual pigments.

The retinas of nocturnal geckos are of particular morphological interest because they possess numerous invaginations of their plasma membrane which are irregularly arranged at the proximal area of the outer segments.
