Summary. Stentor coeruleus and the related Blepharisma japonicum possess photoreceptor systems that render the cells capable of avoiding light. On account of this unique feature, these ciliates exhibit photodispersal as they tend to swim away from a bright illumin ation and accumulate in shady or dark areas. The observed photobehaviour is largely the result of a step-up photophobic response displaye d by both ciliates, although other behavioral reactions like phototaxis or photokinesis may also…

Signal Recognition in Lower Organisms: Light-Induced Control of Cell Movement in the Ciliates Blepharisma and Stentor

It is shown that the study of protozoa and their sensory properties may also hold a key to discovery of as-yet unresolved molecular mysteries in the future.

A Videomicroscopic Study of the Effect of l-cis-Diltiazem on the Photobehavior of Stentor coeruleus¶

The obtained behavioral results support the suggestion that the photosensitive ciliate S. coeruleus possesses cGMP-gated channels, which may be involved in the process of light signal transduction for the motile photophobic response.

The present work opens up new perspectives on the primary phototransduction steps of B. japonicum's light perception through a joined approach by steady-state fluorescence spectroscopy, time-resolved fluorescence anisotropy and sub-picosecond transient absorption spectroscope.

Results Characterization of the Photoresponse in Wild-type Cells

The data demonstrate that the photophobic response of Paramecium tetraurelia can be genetically dissected as a means of elucidating the olecular mechanisms of the light response.

Alterations of photophobic motile response in Stentor by cyclic guanosine 3',5'-monophosphate-elevating agents

Behavioral observations suggest that in vivo, the internal level of presumed cGMP, but not cAMP, is possibly a limiting factor for the time course of the motile avoiding response of Stentor, and they further support the hypothesis that cG MP metabolism may play a role in photosignal transduction in these cells.

The main molecular mechanisms connecting the early event of photon absorption to the formation of the signalling state down to the dark steps of the transduction chain are discussed and the possible importance of an intensive multidisciplinary approach to these problems in an evolutionary perspective is outlined.

Photo-dependent population dynamics of Stentor coeruleus and its consumption of Colpidium striatum

The predatory protozoan Stentor coeruleus Ehrenberg, 1830 is known to show photosensitivity and photodisper- sion, avoiding regions of high light intensity as an antipredation strategy. This

PHOTOSENSORY TRANSDUCTION IN CILIATES. I. AN ANALYSIS OF LIGHT‐INDUCED ELECTRICAL AND MOTILE RESPONSES IN Stentor coeruleus

The action spectrum for thePhotoreceptor potential amplitude of Stentor resembled the action spectra for the latency of ciliary reversal and the photoresponsiveness, iondicating that the photomovement response and membrane potential changes are coupled through the same photosensor system.

PHOTOSENSORY TRANSDUCTION IN CILIATES. III. THE TEMPORAL RELATION BETWEEN MEMBRANE POTENTIALS AND PHOTOMOTILE RESPONSES IN Blepharisma japonic urn

The analysis of temporal relationships between the electrophysiological responses and the motile events showed that latency of an action potential, induced by the receptor potential, correlates well with the latency of a cell stop response, which resembles the time period of the cell's backward swimming (cell rotation).

Step-up photophobic response in the ciliate, Stentor coeruleus

The phobic response is specifically inhibited by the protonophorous uncouplers TPMP+ and FCCP but not by the ionophores gramicidin and A23187.

Results suggest that cellular cGMP serves as a signal modulator in the photophobic response of Blepharisma japonicum.

PHOTOSENSORY TRANSDUCTION IN CILIATES. II. POSSIBLE ROLE OF G‐PROTEIN AND cGMP IN Stentor coeruleus

It is indirectly suggested that the level of cytoplamic cGMP, possibly modulated by a G‐protein‐coupled CGMP phosphodiesterase, plays a phototreasducing role in Stentor.

Several lines of evidence suggest that conspicuous cell organelles such as subpellicular pigment granules, a colored stigma, a watchglass organelle, or a compound crystalline organelle are prerequisites for phototactic orientation of the cells.

Photoreception of Paramecium cilia: localization of photosensitivity and binding with anti-frog-rhodopsin IgG.

Immunocytochemical studies showed that the antibody labeling was localized on both the ciliary and the somatic membranes, raising the possibility that P. bursaria may contain a rhodopsin-like protein as a photoreceptor molecule.

Negative phototaxis in Blepharisma japonicum

The protozoan Blepharisma japonicum showed negative phototaxis caused by transient reversal of the direction of ciliary beat and changes of swimming velocity induced with varying intensities of light, which may contribute to rapid swimming.
