Behavioral mutants of Euglena gracilis: functional and spectroscopic characterization.

Abstract excerpt

Three mutant strains of the phytoflagellate Euglena gracilis Z have been characterized in order to analyze the signal perception and signal transduction pathways involved in photo- and gravitaxis. Using the fluorescence of the chromophoric groups believed to be involved in photoperception (flavins and pterins) a method was developed for an in situ and in vivo detection of the paraxonemal body, the proposed...
