摘要：

Abstract— The phototactic response of Euglena gracilis is suppressed when the organisms are exposed to bright light of wavelength less than 650 nm. Activity returns in the dark, approximately 40 min being required for full restoration. Action spectral measurements demonstrate that the receptor pigment which mediates the suppression response may be a flavoprotein. Evidence is presented which indicates that photosuppression involves a direct action on the photo‐tactic apparatus, perhaps a photobleaching of the tactic photoreceptor pigment.
