One hypothesis of triazine-type herbicide action in photosynthetic material is that the herbicide molecule competes with a secondary quinone acceptor, B, for a binding site at the reaction center of photosystem II. The binding affinity of B has been suggested to change with its level of reduction, being most strongly bound in its semiquinone form. To test this hypothesis, [(14)C]atrazine binding studies have been carried out under different photochemically induced levels of B reduction in Pisum… CONTINUE READING
