Endogenous cyclic electron transport in broken chloroplasts [PDF]
Cyclic electron flow around photosystem I plays an important role in providing sufficient ATP for the photosynthetic assimilation of COz [ 1,2]. Cyclic activity may be observed in isolated intact chloroplasts [2,3] but is lost, along with NADP+ reduction, during the isolation of naked thylakoids; however, addition of ferredoxin has been reported [4,5 ...

Plants often need to withstand multiple types of environmental stresses (e.g., salt and low temperature stress) because of their sessile nature. Although the physiological responses of plants to single stressor have been well-characterized, few studies ...

The objective of this experiment was to study the effects of night chilling on the photosynthetic characteristics of cotton (Gossypium hirsutum L.) at a boll-forming stage. The results suggest that overreduction of PSII after night chilling (≤ 10°C) led

Chlamydomonas (C.) reinhardtii is a potential microalga for lipid production. Autophagy-triggered lipid metabolism in microalgae has not being studied so far from a mutant of proton gradient regulation 1 like (PGRL1) and proton gradient regulation 5 ...

Computational Analysis of Alternative Photosynthetic Electron Flows Linked With Oxidative Stress
During photosynthesis, organisms respond to their energy demand and ensure the supply of energy and redox equivalents that sustain metabolism. Hence, the photosynthetic apparatus can, and in fact should, be treated as an integrated supply-demand system ...

Concerning a Dual Function of Coupled Cyclic Electron Transport in Leaves [PDF]
Coupled cyclic electron transport is assigned a role in the protection of leaves against photoinhibition in addition to its role in ATP synthesis. In leaves, as in reconstituted thylakoid systems, cyclic electron transport requires "poising," i.e. availability of electrons at the reducing side of photosystem I (PSI) and the presence of some oxidized ...

Electron transport and light-harvesting switches in cyanobacteria
Cyanobacteria possess multiple mechanisms for regulating the pathways of photosynthetic and respiratory electron transport. Electron transport may be regulated indirectly by controlling the transfer of excitation energy from the light-harvesting ...

A recent investigation has suggested that the enhanced capacity for PSI-dependent cyclic electron flow (CEF) and PSI-dependent energy quenching that is related to chloroplast structural changes may explain the lower susceptibility of lut2 to combined ...

To explore the protective mechanisms of brassinosteroids in the chill-induced photoinhibition in tomato (Solanum lycopersicum), we studied the effect of foliar sprayed 24-epibrassinolide (EBR, 0.1µM) on the gas exchange, chlorophyll fluorescence ...
