Quality control of Photosystem II: the mechanisms for avoidance and tolerance of light and heat stresses are closely linked to membrane fluidity of the thylakoids

Frontiers in Plant Science, 2016
When oxygenic photosynthetic organisms are exposed to excessive light and/or heat, Photosystem II is damaged and electron transport is blocked. In these events, reactive oxygen species, endogenous radicals and lipid peroxidation products generated by ...

A demonstration of energy transfer from photosystem II to photosystem I in chloroplasts

, 1976
Photosystem I activity of Tris-washed chloroplasts was measured at room temperature as the rate of photoreduction of NADP and as the rate of oxygen uptake mediated by methyl viologen in both cases using dichlorophenolindophenol plus ascorbate as the ...

Moderate photoinhibition of photosystem II protects photosystem I from photodamage at chilling stress in tobacco leaves

Frontiers in Plant Science, 2016
It has been indicated that photosystem I (PSI) is susceptible to chilling-light stress in tobacco leaves, but the effect of growth light intensity on chilling-induced PSI photoinhibition in tobacco is unclear.

From Photosystem I to Photosystem II

N/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.

Acyl lipids in the supramolecular chlorophyll-protein complexes of photosystems - isolation artifacts or integral components regulating their structure and functions?

Acta Societatis Botanicorum Poloniae, 2014
The precise nature of interactions between the chloropnyll-protein complexes related to photosystem I or photosystem II and the acyl lipids in the thylakoid membranes is not yet fully elucidated.

Three dimensional structure of the light-harvesting chlorophyll a/b protein complex from plant chloroplasts [PDF]

, 2002
The light-harvesting chlorophyll a/b protein complex (LHC-II) is the major collector of solar energy in all plants and it binds about half of the chlorophyll in green plants.
