“…8). Moreover, presence of S-arrestin, involved in attenuation of phototransduction cascade in visual photoreceptors of invertebrates (Lieb et al, 1991) and vertebrates (Pfister et al, 1985) as well as in ipRGCs (Cameron and Robinson, 2014), has been reported in both JCs and DO (Mirshahi et al, 1985;van Veen et al, 1986). Because of discrepancies in descriptions of the phototransduction cascade in ipRGCs and invertebrate photoreceptors, it would be premature to assess which one is more similar to the cascade present in JCs and DO.…”

Studies on amphioxus, representing the most basal group of chordates, can give insights into the evolution of vertebrate traits. The present review of amphioxus research is focused on the physiology of light-guided behavior as well as on the fine structure, molecular biology, and electrophysiology of the nervous system, with special attention being given to the photoreceptive organs. The amphioxus visual system is especially interesting because four types of receptors are involved in light detection -dorsal ocelli and Joseph cells (both rhabdomeric photoreceptors) and the frontal eye and lamellar body (both ciliary photoreceptors). Here, we consider how the available information on photoreceptive organs and light-guided behavior in amphioxus helps generate hypotheses about the history of these features during chordate and subsequently vertebrate evolution.

“…To test whether these neurons are indeed functional photoreceptors, we have also used antibodies against arrestin and chaoptin. Visual arrestin, which is important in the deactivation of rhodopsin (Dolph et al 1993) has been found in the retina and some neurons of the brain of Drosophila (Lieb et al 1991;Dolph et al 1993;van Swinderen and Hall 1995). Other investigators have found arrestin in the optic lobes of beetles (Fleissner and Fleissner 2003) and caddisflies (Hagberg 1986), in the protocerebrum of aphids (Gao et al 1999) and in the optic lobes and the central brain of blowflies (Nässel 1987;Cymborowski and Korf 1995).…”

Expression of UV-, blue-, long-wavelength-sensitive opsins and melatonin in extraretinal photoreceptors of the optic lobes of hawkmoths

Lepidopterans display biological rhythms associated with egg laying, eclosion and flight activity but the photoreceptors that mediate these behavioural patterns are largely unknown. To further our progress in identifying candidate light-input channels for the lepidopteran circadian system, we have developed polyclonal antibodies against ultraviolet (UV)-, blue- and extraretinal long-wavelength (LW)-sensitive opsins and examined opsin immunoreactivity in the adult optic lobes of four hawk moths, Manduca sexta, Acherontia atropos, Agrius convolvuli and Hippotion celerio. Outside the retina, UV and blue opsin protein expression is restricted to the adult stemmata, with no apparent expression elsewhere in the brain. Melatonin, which is known to have a seasonal influence on reproduction and behaviour, is expressed with opsins in adult stemmata together with visual arrestin and chaoptin. By contrast, the LW opsin protein is not expressed in the retina or stemmata but rather exhibits a distinct and widespread distribution in dorsal and ventral neurons of the optic lobes. The lamina, medulla, lobula and lobula plate, accessory medulla and adjacent neurons innervating this structure also exhibit strong LW opsin immunoreactivity. Together with the adult stemmata, these neurons appear to be functional photoreceptors, as visual arrestin, chaoptin and melatonin are also co-expressed with LW opsin. These findings are the first to suggest a role for three spectrally distinct classes of opsin in the extraretinal detection of changes in ambient light and to show melatonin-mediated neuroendocrine output in the entrainment of sphingid moth circadian and/or photoperiodic rhythms.
