THE unicellular alga Chlamydomonas reinhardtii responds to weak flashes of light by changing its swimming direction and to brighter flashes with transient backward swimming (the stop or phobic response)1,2. In continuous light the cells swim towards or away from the light source (phototaxis)3,4. This behaviour is controlled by a visual system with a rhodopsin as the functional photoreceptor5,6. Physiological experiments under different ionic conditions have suggested that ionic processes are… Expand
The Photoreceptor Current of the Green Alga Chlamydomonas
TLDR
Several lines of evidences suggest that these photocurrents are the link between light absorption and alteration of the flagellar beating during a movement response. Expand
Desensitization and Dark Recovery of the Photoreceptor Current in Chlamydomonas reinhardtii
TLDR
K+ currents constitute a novel component of the rhodopsin-mediated signaling system in C. reinhardtii that is involved in the process of dark adaptation of the system and desensitization and dark recovery of the extracellularly recorded photoreceptor current were investigated. Expand
Vision in microalgae
TLDR
Elucidation of photoreception in flagellated algae will provide deeper insight into the development of visual systems, starting from single-celled organisms and moving up through higher animals. Expand
Two light-activated conductances in the eye of the green alga Volvox carteri.
TLDR
A model of how different modes of signal transduction are accomplished in this alga under different light conditions is presented, which includes a signal transducer mediating between rhodopsin and the channel. Expand
Photoreceptor current and photoorientation in chlamydomonas mediated by 9-demethylchlamyrhodopsin.
TLDR
Photosignaling by chlamyrhodopsin regenerated with 9-demethylretinal led to reconstitution of all receptor molecules, but sensitivity of the photoreceptor current in cells reconstituted with the analog was smaller compared with retinal-reconstituted cells, indicating a decreased signaling efficiency of the analog receptor protein. Expand
Photophobic responses and phototaxis in Chlamydomonas are triggered by a single rhodopsin photoreceptor
TLDR
The physiological, electrophysiological and biochemical experiments suggest that all behavioural responses are triggered by a single rhodopsin‐type receptor. Expand
Photosensory Functions of Channelrhodopsins in Native Algal Cells †
TLDR
Data is presented showing that the modes of action of both types of sensory rhodopsins are different in native cells such as Chlamydomonas reinhardtii than in heterologous expression systems, and also differ between the two types of rhodopins. Expand
Rhodopsin-mediated photosensing in green flagellated algae.
TLDR
Green flagellated algae possess a primitive visual system that regulates the activity of their motor apparatus, which serves to align the swimming path with the direction of the light stimulus, whereas processes of energy metabolism determine whether the oriented movement is directed towards or away from the light source. Expand
Mutational analysis of the phototransduction pathway of Chlamydomonas reinhardtii
TLDR
To identify components that make up this signal transduction pathway, nonphototactic strains were generated by insertional mutagenesis and seven new phototaxis genes were identified (ptx2-ptx8); alleles of six of these are tagged by the transforming DNA and therefore should be easily cloned. Expand

In vitro identification of rhodopsin in the green alga Chlamydomonas.
TLDR
The in vitro identification of endogenous retinal and a rhodopsin in Chlamydomonas cell extracts and purified membrane preparations is reported and it is concluded that this protein is the visual photoreceptor inChlamyDomonas. Expand
Calcium couples flagellar reversal to photostimulation in Chlamydomonas reinhardtii
SEVERAL recent findings1–3 suggest that the intracellular concentration of free calcium, [Ca]i, has an important role in the regulation of ciliary and flagellar beating. For example, ParameciumExpand
Two components of photoreceptor potential in phototaxis of the flagellated green alga Haematococcus pluvialis.
TLDR
The results indicate that the photoreceptor potential in phototaxis comprises two components, which could be interpreted as light-induced charge movement within the Photoreceptor molecules and changes in ion permeability of the cell membrane. Expand
A rhodopsin is the functional photoreceptor for phototaxis in the unicellular eukaryote Chlamydomonas
TLDR
It is shown here that the unicellular alga Chlamydomonas does indeed use a rhodopsin photoreceptor, and that 11-cis-retinal is the natural chromophore and that the protein environment of this retinal is similar to that found in bovine rhodopin, suggesting homology with the r Rhodopsins of higher organisms.

THE ROLE OF CALCIUM IN Chlamydomonas PHOTOMOVEMENT RESPONSES AS ANALYSED BY CALCIUM CHANNEL INHIBITORS
TLDR
It is concluded that phototaxis and stop response in Chlamydomonas are regulated by three distinguishable drug receptor sites, one of them controls photot axis and is sensitive to verapamil, and the other two seem to be localized in the plasma membrane and function as ion channels. Expand
Probing visual transduction in a plant cell: Optical recording of rhodopsin-induced structural changes from Chlamydomonas reinhardtii.
TLDR
Flash-induced light scattering changes have been recorded which are repeatable, graded with photon exposure, and adaptive, and correlate kinetically with flash-induced movement responses. Expand
REVERSIBLE BLEACHING OF Chlamydomonas reinhardtii RHODOPSIN in vivo
TLDR
The phototactic sensitivity of Chlamydomonas reinhardtii is bleaching of rhodopsin by more than 99% and reconstitution by de novo synthesized or by added retinal by adding retinal is explained. Expand

The utility of a commercially available motion analysis system for the analysis of the Chlamydomonas stop response is presented and a kinetic model for the description of adaptation is presented. Expand
Submicromolar levels of calcium control the balance of beating between the two flagella in demembranated models of Chlamydomonas
TLDR
The results show that there are functional differences between the two axonemes of Chlamydomonas, and the differential responses of the ax onemes to submicromolar concentrations of Ca++ may form the basis for phototactic turning. Expand
