 Title    Effects of S-^^-DichlorophenyO-N-N'-Dimethylurea on Oxygen Evolution and Fluorescence by Whole Filaments and Isolated Thylakoids of the Cyanobacterium Anabaena cylindrica  
 Abstract    The site of inhibition of DCM U against photosystem II in the cyanobacterium (Blue-green alga) Anabaena cylindrica was examined in electron transport and fluorescence studies. Isolated thylakoids catalyzed silicomolybdate photoreduction using H zO as electron donor; the steady-state reaction was completely inhibited by DCM U. This reaction is insensitive to DCM U in chloro­ plasts, since silicomolybdate accepts electrons from the prim ary photosystem II acceptor, and thus before the site of action o f D CM U in higher plants. DCM U did not increase the steady-state level of fluorescence by inact A. cylindrica, nor affect the monophasic fluorescence induction, with
