Short term effect of ultraviolet-B radiation on photosystem 2 photochemistry in the cyanobacteriumSynechococcus 6301

Exposure of intact cells of theSynechococcus 6301 to UV-B radiation induced a loss in photosystem 2 (PS 2) electron transport activity prior to the alteration in pigment complexes. Thus the degradation of PS 2 was not directly related to pigment alteration.

Keywords: absorption spectra; chlorophyll; energy transfer; fluorescence emission; excitation spectra; phycocyanin
