Functional analysis of the eyespot in Chlamydomonas reinhardtii mutant ey 627, mt (-).

The function of the eyespot in phototaxis of the flagellate green alga Chlamydomonas reinhardtii Dangeard was studied using quantitative reflection confocal laser scanning microscopy and photoelectric measurements. The reflective properties of the eyespot and the photoreceptor current of the C. reinhardtii eyespot mutant ey 627, mt (-) were compared with those of Chlamydomonas strains possessing a well-developed eyespot.
