Antenna Protein Conformational Changes Revealed by Resonance Raman Spectroscopy,tion. After summarizing these in vitro results, we will explain how similar measurements in chloroplasts and whole leaves confirmed that these conformational changes were also seen in vivo, correlating with NPQ. Finally, we will present a model to explain our conclusions and will, furthermore, intro

Molecular Mechanisms for Activation of Non-Photochemical Fluorescence Quenching: From Unicellular Aion of thylakoid membrane complexes upon lumen acidification, which is indispensable for the generation of the dissipative state. Upon reorganization, two distinct quenching components are generated: one is tightly connected to the photosystem II (PS II) reaction center and the other is located in a

In some cases, correlations between the observed reorganizations and NPQ have been well established. In many c

Finally, we present an integrated working model for the structural events involved in qE formation, and the factors that trigger the transition. This model incorporates availab

Control of Non-Photochemical Exciton Quenching by the Proton Circuit of Photosynthesis, of . triggers the “energy-dependent”, or qE component of NPQ, which protects photosystem II from photodamage and regulates electron transfer through the cytochrome ... complex, thereby preventing damage to photosystem I. The extent and mode of storage in ΔpH and ΔΨ of . are regulated by several pro

Desiccation-Induced Quenching of Chlorophyll Fluorescence in Cryptogams, mosses. This quenching is not inhibited by the electron transport inhibitor DCMU, the uncoupler nigericin, or the inhibitor of zeaxanthin formation, dithiothreitol. Since desiccation-induced quenching is, however, inhibited by glutaraldehyde and released by heating above 40–50 °C, this quenching ma
