Abstract

The external electric-field induced luminescence in hypotonically swollen thylakoid vesicles consists of two kinetically different phases, rapid R and slow S, which have been characterized previously (Symons, M., Malkin, S. and Korenstein, R. (1984) Biochim. Biophys. Acta, 767, 223-230). We show that the R phase is elicited by precursors originating in Photosystem I and that S is created through Photosystem II activity. This is substantiated by the difference of the two luminescence phases regarding their action spectrum, sensitivity to electron acceptors, electron-transport inhibitors and heat treatment.
