【 摘 要 】

Subfractionation of chloroplast thylakoids at elevated temperatures shows that above 35°C the photosystem II core and some of its light-harvesting complex (LHC-II) migrates laterally from the appressed thylakoid regions out to the non-appressed regions, leaving behind free LHC-II in the appressions. These structural rearrangements of the thylakoid membrane are largely reversible upon lowering the temperature and may play a physiological role in preventing overexcitation of photosystem II under high light intensities which normally induce elevated leaf temperatures.
