Journal ArticleDOI
Photoinhibition and zeaxanthin formation in intact leaves : a possible role of the xanthophyll cycle in the dissipation of excess light energy.
TL;DR: Bjorkman et al. as discussed by the authors found that exposure of leaves of Populus balsamifera, Hedera helix, and Monstera deliciosa to excess excitation energy (high light, air; weak light, 2% O2, 0% CO2) led to massive formation of zeaxanthin and a decrease in violaxanthins.
Journal ArticleDOI
Zeaxanthin and the Heat Dissipation of Excess Light Energy in Nerium oleander Exposed to a Combination of High Light and Water Stress.
TL;DR: The resistance of this species to the destructive effects of excess light appears to be related to interconversions between beta-carotene and the three carotenoids of the xanthophyll cycle.
Journal ArticleDOI
Inhibition of Zeaxanthin Formation and of Rapid Changes in Radiationless Energy Dissipation by Dithiothreitol in Spinach Leaves and Chloroplasts
Barbara Demmig-Adams,William W. Adams,Ulrich Heber,Spidola Neimanis,Klaus Winter,Almuth Krüger,Franz-Christian Czygan,Wolfgang Bilger,Olle Björkman +8 more
TL;DR: The inhibition of zeaxanthin-associated fluorescence quenching by dithiothreitol provides further evidence that there exists a close relationship between zexanthin and potentially photoprotective dissipation of excess excitation energy in the antenna chlorophyll.
Journal ArticleDOI
Photochemical efficiency of photosystem II, photon yield of O2 evolution, photosynthetic capacity, and carotenoid composition during the midday depression of net CO2 uptake in Arbutus unedo growing in Portugal
Barbara Demmig-Adams,William W. Adams,Klaus Winter,A. Meyer,Ulrich Schreiber,João Pereira,Almuth Krüger,Franz-Christian Czygan,Otto L. Lange +8 more
TL;DR: During the “midday depression” of net CO2 exchange in the mediterranean sclerophyllous shrub Arbutus unedo, examined in the field in Portugal during August of 1987, several parameters indicative of photosynthetic competence were strongly and reversibly affected.
Journal ArticleDOI
Light Response of CO2 Assimilation, Dissipation of Excess Excitation Energy, and Zeaxanthin Content of Sun and Shade Leaves
TL;DR: The increase in zeaxanthin was paralleled by an increase in the rate constant for radiationless energy dissipation k(D), which opens the possibility that zeax anthin is related to the rapidly relaxing "high-energy-state quenching" in leaves.
