Journal ArticleDOI
Superoxide and Singlet Oxygen Produced within the Thylakoid Membranes Both Cause Photosystem I Photoinhibition
TL;DR: It is suggested that PSI photoinhibition is caused by both O2− and 1O2 produced within the thylakoid membranes when electron carriers in PSI become highly reduced, and it is found that not only superoxide (O2−) but also singlet oxygen (1O2) is involved in PSi photoin inhibition induced by rSP treatment.
Journal ArticleDOI
Repetitive Short-Pulse Light Mainly Inactivates Photosystem I in Sunflower Leaves
TL;DR: Analysis of the effects of repetitive illumination by short-pulse (SP) light of sunflower leaves on the photosynthetic electron flow found that repetitive illumination with SP light did not induce the oxidation of P700 in PSI, and mainly inactivated PSI.
Journal ArticleDOI
Chloroplastic ATP synthase builds up a proton motive force preventing production of reactive oxygen species in photosystem I.

TL;DR: The results suggested that chloroplastic CF0 CF1 -ATP synthase adjusts the redox state of the PET chain, especially for PSI, by modulating H+ efflux activity across the thylakoid membranes.
Journal ArticleDOI
Diversity of strategies for escaping reactive oxygen species production within photosystem I among land plants: P700 oxidation system is prerequisite for alleviating photoinhibition in photosystem I

TL;DR: It is demonstrated, for the first time, that gymnosperms, ferns and mosses/liverworts possess a protection mechanism against photoinhibition of PSI that differs from that of angiosperms.
Journal ArticleDOI
Responses of the Photosynthetic Electron Transport Reactions Stimulate the Oxidation of the Reaction Center Chlorophyll of Photosystem I, P700, under Drought and High Temperatures in Rice.
TL;DR: Results indicate that the drought stress responses of the respective PET reactions are closely associated with each other in the oxidization of P700 and that such responses are stimulated at high temperatures.
