Replacement of photosynthetic electron transport inhibitors by silico molybdate

, : Replacement of photosynthetic electron transport inhibitors by silico molybdate. Physiologia Plantarum 54(2): 221-224

KCN-treated spinach [Spinacia oleracea cv. Atlanta] chloroplasts, their photosystem I being ineffective, exhibit a single reaction site for silicomolybdate. Using this heteropolyanion as electron acceptor, photosynthetic O2 evolution is partially inhibited by ureas, triazines or phenylpyridazinone herbicides, their inhibitory effect depending on the concentration of silicomolybdate. Labeled atrazine attached to isolated chloroplast material is competitively replaced by silicomolybdate in the same manner as ureas competing with a triazine herbicide. Apparently, silicomolybdate is bound and reduced at the herbicide-binding protein, and the inhibition of silicomolybdate reduction by herbicides such as DCMU [3-(3,4-dichlorophenyl)-1,1-dimethylurea] is due to loss of reaction sites for silicomolybdate.
