| Abstract: | The light-induced dark-reversible ESR signal in chloroplast fragments enriched in photosystem II and free from P700 contamination has been observed in the presence of silicomolybdate as an electron acceptor operating directly on the photosystem II primary acceptor. The signal at g = 2.0025 and with line-width ΔHpp = 9G rises and decays in close correlation with the photobleaching band centered at 680 nm and the minor peak at 435 nm. |
