 Title    Comparison of Diuron-and Phenol-Type Inhibitors: Additional Inhibitory Action at the Photosystem II Donor Site  
 Abstract    Inhibitors o f photosystem II reactions from the "diuron-type" and "phenol-type" have been compared regarding their m echanism o f action. "Diuron-" as well as "phenol-type" inhibitors act at the acceptor site o f photosystem II by displacing the secondary acceptor quinone Q B from its binding site. "Phenol-type" inhibitors additionally interfere with the donor site, which is demonstrated in studies o f chlorophyll fluorescence and lum inescence. This m echanism o f action is shown to be similar but not identical to that reported for hydroxylam ine.

 Title    Inhibition of Phytoene Desaturase — the Mode of Action of Certain Bleaching Herbicides  
 Abstract    Assay systems have been developed in order to differentiate betw een the m odes o f action o f certain bleaching herbicides. These include inhibition o f chlorophyll or carotenoid biosynthesis, and initiation o f pigment degradation. H erbicidal com pounds with phytoene desaturase as their primary target site were investigated in a cell-free carotenogenic system from Aphanocapsa. In a comparative study, the structural prerequisites for inh ib ition o f phytoene desaturase were estab­ lished for both benzophenone analogs and various m -phenoxybenzam ides. This inhibitory action o f the latter compounds is enhanced by lipophilic groups with certain steric properties.
