My colleague, Anca Galasiu, and I identifi ed three broad processes through which residential windows and skylights can affect people in their homes, for good and ill: visual processes, acting primarily through light detected at the retina by rods and cones; non-visual ocular processes, acting primarily through light detected at the retina by intrinsically photoreceptive
retinal ganglion cells; and processes occurring in the skin (Veitch and Galasiu 2012).
In the frog photoreceptor, Besharse and Pfenninger (1980) have suggested that cytoplasmic vesicles are the precursors of the photoreceptive
membranes and fuse with the plasma membrane adjacent to the connecting cilium.
circadian clocks throughout Drosophila.
The research reveals that the gene called melanopsin causes nerve cells to become photoreceptive
The pineal gland has the function of photoreceptive
in fish, amphibious and reptiles, and as a biological clock in birds (Reiter, 1989).
Perhaps the most important of all developments is a newly discovered photoreceptive
sensory system, housed in the eye, but not involved in vision.
The methods generally comprise introducing into a genome of an animal a genetic construct comprising a transcriptional regulatory element operably linked to a heterologous marker gene encoding a marker, wherein the element drives expression of the marker across genera transgenic in the construct sufficient to visually detect the marker in photoreceptive
cells or organs, and selecting for transgenesis by visually detecting the marker in a photoreceptive
cell or organ of the animal.
At least in other species, the leaves are also photoreceptive
organs that contribute to the stem growth response (Casal and Smith, 1988).
The tip of the wand was bent at 90 [degrees] from the long (handle) axis and contained a photoreceptive
What we claimed, and it's as correct as ever, is that the eyes themselves, the photoreceptive
organs, developed independently at least 40 times.
Like sabellids (Lawrence and Krasne, 1965; Ermak and Eakin, 1976), the cerebral ocellar photoreceptors of serpulids are rhabdomeric in nature, with the elaborated photoreceptive
membranes being formed from microvilli that project into a pigment cup (Figs.
