Phosphorylation coupled to non‐cyclic electron flow in photosystem I [PDF]
FEBS Letters, 1971 Electron flow pathways in islated chloroplasts are associated with one or with both photosystems, and may be of a cyclic or a non-cyclic nature. Photoinduction of such electron flow paths is accompanied by the synthesis of ATP [I] . The localization of the sites of ATP formation along these electron flow pathways is a problem of great interest.

Regulation of Chloroplast ATP Synthase Modulates Photoprotection in the CAM Plant Vanilla planifolia
Cells, 2022 Generally, regulation of cyclic electron flow (CEF) and chloroplast ATP synthase play key roles in photoprotection for photosystems I and II (PSI and PSII) in C3 and C4 plants, especially when CO2 assimilation is restricted.

Induction Kinetics of Photosystem I-Activated P700 Oxidation in Plant Leaves and Their Dependence on Pre-Energization [PDF]
, 2010 Absorbance changes ¿A 810 were measured in pea (Pisum sativum L., cv. Premium) leaves to track redox transients of chlorophyll P700 during and after irradiation with far red (FR) light under various preillumination conditions in the absence and presence ...

Cyclic electron flow in C3 plants
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2006 This paper summarized our present view on the mechanism of cyclic electron flow in C3 plants. We propose that cyclic and linear pathways are in competition for the reoxidation of the soluble primary PSI acceptor, Ferredoxin (Fd), that freely diffuses in the stromal compartment.

Regulation of cyclic electron flow through ferredoxin redox partners [PDF]
, 2023 Photosynthetic organisms must balance their electron transport between linear and cyclic electron flow. Linear electron flow (LEF) is required for carbon fixation whereas cyclic electron flow (CEF) must be upregulated under conditions where the Calvin ...

Cyclic electron flow is redox-controlled but independent of state transition [PDF]
Nature Communications, 2013 Photosynthesis is the biological process that feeds the biosphere with reduced carbon. The assimilation of CO2 requires the fine tuning of two co-existing functional modes: linear electron flow, which provides NADPH and ATP, and cyclic electron flow, which only sustains ATP synthesis.

Rates and Roles of Cyclic and Alternative Electron Flow in Potato Leaves [PDF]
Plant and Cell Physiology, 2007 Measurements of 810 nm transmittance changes in leaves, simultaneously with Chl fluorescence, CO(2) uptake and O(2) evolution, were carried out on potato (Solanum tuberosum L.) leaves with altered expression of plastidic NADP-dependent malate dehydrogenase. Electron transport rates were calculated: J(C) from the CO(2) uptake rate considering ribulose-1,
