Photo-Signal Transduction in Motile Ciliate Blepharisma.
Abstract
The photosensing processes in Stentor coeruleus and Blephansmajaponicwn can be described within the photo-signal transduction cascade shown above, with stentorin and blepharismin serving as the photosensor molecules, respectively. In the photophobic responses of these climates, light signal (red wavelength light and intensity gradient) is perceived by the photosensor molecules localized in the pigment granule. A signal transduction then leads to the reversal of the direction of ciliary beating that is entailed in the stop-turning motion of the cell away from the source of light. In this paper we briefly describe the photosensory transduction which utilizes stentorin and blepharismin as the photosensor molecules.
