Sustained diurnal stimulation of cyclic electron flow in two tropical tree species Erythrophleum guineense and Khaya ivorensis

open access: yesFrontiers in Plant Science, 2016
The photosystem II (PSII) activity of C3 plants is usually inhibited at noon associated with high light but can be repaired fast in the afternoon. However, the diurnal variation of photosystem I (PSI) activity is unknown.

Trehalose as a tool for studying the molecular mechanisms of electron transfer in photosynthetic systems

open access: yesFrontiers in Photobiology
In this review, we consider the effects of trehalose on charge transfer processes in three distinct photosynthetic systems under different conditions, namely: (i) the effect of relative hydration of the trehalose glassy matrix on forward and backward ...

The functional role of protein dynamics in photosynthetic reaction centers investigated by elastic and quasielastic neutron scattering

open access: yesEPJ Web of Conferences, 2015
This short review summarizes our current knowledge about the functional relevance of protein dynamics in photosynthetic reaction centers. In the case of Photosystem II membrane fragments, elastic and quasielastic neutron scattering experiments reveal a ...

Applications of Delayed Fluorescence from Photosystem II

open access: yesSensors, 2013
While photosystem II (PSII) of plants utilizes light for photosynthesis, part of the absorbed energy may be reverted back and dissipated as long-term fluorescence (delayed fluorescence or DF). Because the generation of DF is coupled with the processes of

Cytoplasmic N-Terminal Protein Acetylation Is Required for Efficient Photosynthesis in Arabidopsis [PDF]

open access: yes, 2003
The Arabidopsis atmak3-1 mutant was identified on the basis of a decreased effective quantum yield of photosystem II. In atmak3-1, the synthesis of the plastome-encoded photosystem II core proteins D1 and CP47 is affected, resulting in a decrease in the ...

Arabidopsis STN7 Kinase Provides a Link between Short- and Long-Term Photosynthetic Acclimation [PDF]

open access: yes, 2009
Flowering plants control energy allocation to their photosystems in response to light quality changes. This includes the phosphorylation and migration of light-harvesting complex II (LHCII) proteins (state transitions or short-term response) as well as ...

Induction Kinetics of Photosystem I-Activated P700 Oxidation in Plant Leaves and Their Dependence on Pre-Energization [PDF]

open access: yes, 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 ...

From Photosystem I to Photosystem II

open access: yesN/A, 2014
Ik heb gericht op de studie van de fotosynthetische complexen in Chlamydomonas reinhardtii. Het doel was om uitgebreide structurele en functionele informatie over Fotosysteem I en Fotosysteem II te krijgen en om hun flexibiliteit in verschillende omgevingsomstandigheden te testen.

Selenium induced lower respiratory potential in Glycine max (L.) Merr.

open access: yesActa Agriculturae Slovenica, 2010
Effect of selenium (Se) was studied in soybean (Glycine max (L.) Merr.) cv. Olna in Ljubljana, Slovenia. Se was added to plants as foliary spraying. Quantum yield of photosystem II (PSII) and respiratory potential measured as ETS activity of mitochondria
