Protection of photosynthetic O2 evolution against heat inactivation: the role of chloride, pH and coupling status.

C Critchley1, R K Chopra.   

Abstract

Heat inactivation of photosynthetic O2 evolution was studied in isolated thylakoids from spinach (Spinacia oleracea) and mangrove (Avicennia marina) leaves. Different temperatures, salt, pH and uncoupler effects were investigated. From these results and others in the literature it was concluced that chloride loss from the membrane and, more specifically, the oxygen-evolving complex of photosystem II, may be the cause of inhibition of oxygen evolution during heat inactivation.
