Structure-activity relationships of quinone and acridone photosystem II inhibitors
1995
Draber, W. | Trebst, A. | Oettmeier, W.
Photosynthesis inhibition was determined with thylakoids of the green alga Chlamydomonas reinhardtii on eleven acridones, twelve 1,4-benzoquinones and fifteen 1,4-naphthoquinones. The wild type and five mutants of the algae were used. The mutants had known changes in the inhibitor-binding region of the D-1 protein. The compounds showed reduced as well as enhanced inhibitory activity up to two orders of magnitude. Their resistance/supersensitivity pattern and structure-activity studies revealed that the inhibitory behaviour resembles that of the nitrophenols.
