The effect of 3-(3,4-dichlorophenyl)-1,1-dimethyl urea (diuron) binding at the secondary quinone (QB) binding site of reaction center II (RCII), on the high-light-induced degradation of the RCII proteins D1 and D2, and the core proteins CP43 and CP47 was investigated in vivo in Chlamydomonas reinhardtii.

These Chls are axially coordinated by the D1-H118 and D2-H117 residues and are in close association with the proximal Chl antennae proteins, CP43 and CP47.

CP47, the other major chlorophyll-binding protein, was present in reduced but significant amounts in the thylakoid.
Herbicide binding (diuron) was lost in all but one mutant indicating the PSII components are not assembled into functionally intact complexes.

Additional effects on the donor side cannot yet be excluded. (4) The binding affinity for the herbicide DCMU is unaltered. (5) The mutants grow photosynthetically, but at a decreased (approximately 70% of the wild type) level. (6) The Fo level was elevated (approximately 40-50%) which could be due to a decrease in the excitation energy transfer from the antenna to the PSII reaction center, and/or to an increased level of [QA-] in the dark. (7) A decreased (approximately 10%) ratio of F685 (mainly from CP43) and F695 (mainly from CP47) to F715 (mainly from PSI) emission bands at 77 K suggests a change in the antenna complex.

Photosynth Res. 2008 Oct-Dec;98(1-3):449-68. Epub 2008 Sep 6.


We discuss an indirect mechanism mediated through electrostatic and/or surface charge effects and the possibility of more pleiotropic effects arising from decreased stability of the D1/D2 and D1/CP47 interfaces.
