The structure and function of eukaryotic photosystem I [PDF]

, 2011
Eukaryotic photosystem I consists of two functional moieties: the photosystem I core, harboring the components for the light-driven charge separation and the subsequent electron transfer, and the peripheral light-harvesting complex (LHCI).

Multiple impacts of loss of plastidic phosphatidylglycerol biosynthesis on photosynthesis during seedling growth of Arabidopsis

Frontiers in Plant Science, 2016
Phosphatidylglycerol (PG) is the only major phospholipid in the thylakoid membrane in cyanobacteria and plant chloroplasts. Although PG accounts only for ~10% of total thylakoid lipids, it plays indispensable roles in oxygenic photosynthesis. In contrast

Consequences of Decreased Light Harvesting Capability on Photosystem II Function in Synechocystis sp. PCC 6803

Life, 2014
Cyanobacteria use large pigment-protein complexes called phycobilisomes to harvest light energy primarily for photosystem II (PSII). We used a series of mutants with partial to complete reduction of phycobilisomes to examine the effects of antenna ...

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

Frontiers 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.

Molecular mechanism of photosystem I assembly in oxygenic organisms [PDF]

, 2015
Photosystem I, an integral membrane and multi-subunit complex, catalyzes the oxidation of plastocyanin and the reduction of ferredoxin by absorbed light energy.

Study of factors controlling the photoprotection capacity of the thylakoid membrane [PDF]

, 2010
PhDPlants require light for the process of photosynthesis, but excess of light absorption can cause photooxidative damage. To avoid this damage, plants have evolved a photoprotective mechanism to dissipate excess light energy as heat in a process ...

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

Frontiers 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 ...

Data_Sheet_1_Diversity Among Cyanobacterial Photosystem I Oligomers.docx

, 2022
Unraveling the oligomeric states of the photosystem I complex is essential to understanding the evolution and native mechanisms of photosynthesis. The molecular composition and functions of this complex are highly conserved among cyanobacteria, algae ...
