Abstract

In spinach thylakoids, the quenching of the singlet excited state in the photosystem II antenna by m-dinitrobenzene does not change the rate of the light induced degradation of the D1 reaction centre protein and offers only limited protection against photoinhibition itself. These results are discussed in terms of the role of non-photochemical quenching as a photoprotective strategy.
