The mechanism of cyclic electron flow
Biochimica Et Biophysica Acta - Bioenergetics, 2019 Apart from the canonical light-driven linear electron flow (LEF) from water to CO2, numerous regulatory and alternative electron transfer pathways exist in chloroplasts. One of them is the cyclic electron flow around Photosystem I (CEF), contributing to photoprotection of both Photosystem I and II (PSI, PSII) and supplying extra ATP to fix atmospheric ...

Maximal cyclic electron flow rate is independent of PGRL1 in Chlamydomonas
Biochimica Et Biophysica Acta - Bioenergetics, 2019 Cyclic electron flow (CEF) is defined as a return of the reductants from the acceptor side of Photosystem I (PSI) to the pool of its donors via the cytochrome b6f. It is described to be complementary to the linear electron flow and essential for photosynthesis.

Cyclic electron flow: facts and hypotheses
Photosynthesis Research, 2016Over the last 15 years, research into the process of cyclic electron flow in photosynthesis has seen a huge resurgence. Having been considered by some in the early 1990s as a physiologically unimportant artefact, it is now recognised as essential to normal plant growth.

Cyclic electron flow around Photosystem II in vivo
Photosynthesis Research, 1996The 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.

The antimycin A-sensitive pathway of cyclic electron flow: from 1963 to 2015
Photosynthesis Research, 2016Cyclic 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.

Flash spectroscopic studies of cyclic electron flow in intact chloroplasts
Biochemical and Biophysical Research Communications, 1978Abstract 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.

The cyclic electron flow (CEF) around photosystem I (PSI) plays a crucial role in photosynthesis and also functions in plant tolerance of abiotic environmental stress. However, the role of PGR5/PGRL1- and NDH-dependent CEF in tomato under hightemperature (HT) is poorly understood. Here, we assessed the photoprotective effect of these pathways in tomato

Isolation of the elusive supercomplex that drives cyclic electron flow in photosynthesis
Nature, 2010Photosynthetic 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)
