Abstract
When the unicellular photosynthetic alga Chlamydomonas is faced with changes in direction, wavelength or intensity of the ambient light, it exhibits distinct behavioral responses, which are direction changes if the changes are small or stop responses upon larger changes. At continuous irradiation Chlamydomonas orients to or away from the light source (positive or negative phototaxis). These movement responses have been under investigation for more than 100 years (Pfeffer, 1904; Nultsch and Häder, 1988) but neither the photoreceptor nor the signal transduction process have been characterized in detail.
