The Antimycin A-Sensitive Pathway of Cyclic Electron Flow: From 1963 to 2015

Photosynthesis Research, 2016
Cyclic electron flow has puzzled and divided the field of photosynthesis researchers for decades. This mainly concerns the proportion of its overall contribution to photosynthesis, as well as its components and molecular mechanism. Yet, it is irrefutable that the absence of cyclic electron flow has severe effects on plant growth.

Exogenous trehalose protects photosystem II by promoting cyclic electron flow under heat and drought stresses in winter wheat.

Plant biology, 2021
Drought and the rising global temperature are important factors reducing wheat production. Trehalose protects the reaction center and improves photosystem II (PS II) activity under diverse stress conditions.

Isolation of the Elusive Supercomplex That Drives Cyclic Electron Flow in Photosynthesis

Nature, 2010
Photosynthetic light reactions establish electron flow in the chloroplast's thylakoid membranes, leading to the production of the ATP and NADPH that participate in carbon fixation. Two modes of electron flow exist-linear electron flow (LEF) from water to NADP(+) via photosystem (PS) II and PSI in series and cyclic electron flow (CEF) around PSI (ref. 2)

Cyclic electron flow around Photosystem II in vivo

Photosynthesis Research, 1996
The oxygen flash yield (YO2) and photochemical yield of PS II (ΦPS II) were simultaneously detected in intact Chlorella cells on a bare platinum oxygen rate electrode. The two yields were measured as a function of background irradiance in the steady-state and following a transition from light to darkness.

Cyclic electron flow protects photosystem I donor side under low night temperature in tomato

Environmental and Experimental Botany, 2020
Cyclic electron flow (CEF) around photosystem I (PSI) is an important photoprotective mechanism, mediated mainly by PGR5/PGRL1 proteins and the chloroplast NAD(P)H dehydrogenase (NDH) complex. Here, chemical inhibition of PGR5/PGRL1- or NDH-dependent CEF

Elevated air temperature damage to photosynthetic apparatus alleviated by enhanced cyclic electron flow around photosystem I in tobacco leaves.

Ecotoxicology and Environmental Safety, 2020
High temperature can lead to increased production of excess light energy, thus reducing photosynthetic capacity in plants. Photosynthetic cyclic electron flow (CEF) in photosystem I (PSI) can effectively protect photosystems, but its physiological ...

Environmental and Experimental Botany, 2019
The effect of drought on the prompt chlorophyll a fluorescence (PF) transient (OJIP), delayed chlorophyll a fluorescence (DF), modulated 820-nm reflection (MR), energy conversion efficiencies in photosystems (PS) I and II, and cyclic electron flow (CEF ...

Cyclic Electron Flow Around Photosystem I Is Essential for Photosynthesis

Nature, 2004
Photosynthesis provides at least two routes through which light energy can be used to generate a proton gradient across the thylakoid membrane of chloroplasts, which is subsequently used to synthesize ATP. In the first route, electrons released from water in photosystem II (PSII) are eventually transferred to NADP+ by way of photosystem I (PSI).

Flash spectroscopic studies of cyclic electron flow in intact chloroplasts

Biochemical and Biophysical Research Communications, 1978
Abstract The kinetic behaviours of cytochrome b -563 and cytochrome f are shown to be consistent with their participation in coupled cyclic electron flow in intact chloroplasts. Electron transfer between cytochromes b -563 and cytochrome f is antimycin sensitive.
