title: UV effects on the pigmentation of the flagellate Cyanophora paradoxa - Biochemical and spectroscopic analysis.
abstract: Pigmentation and protein composition of the freshwater flagellate, Cyanophora paradoxa, were studied after exposure of the cells to solar and artificial ultraviolet radiation. The water soluble chromoproteins (phycobilins) are affected by even short exposure, while the membrane bound chlorophyll protein complexes are hardly altered as shown by both Polyacrylamide gel electrophoresis and fast protein liquid chromatography (FPLC). Fluorescence spectra indicate that the energy transfer from the accessory pigments to the reaction center of photosystem II is impaired by ultraviolet radiation.
