One-step isolation and biochemical characterization of a highlyactive plant PSII monomeric core [PDF]

open access: yes, 2011
We describe a one-step detergent solubilization protocol for isolating a highly active form of Photosystem II (PSII) from Pisum sativum L. Detailed characterization of the preparation showed that the complex was a monomer having no light harvesting ...

Prochlorococcus and Synechococcus have evolved different adaptive mechanisms to cope with light and UV stress [PDF]

open access: yes, 2012
Prochlorococcus and Synechococcus, which numerically dominate vast oceanic areas, are the two most abundant oxygenic phototrophs on Earth. Although they require solar energy for photosynthesis, excess light and associated high UV radiations can induce ...

Interactions of Photosystem I with Plasmonic nanostructures [PDF]

open access: yes, 2012
The plasmonic interaction effects of various nanostructures on the fluorescence properties of photosystem I as found by single-molecule spectroscopy are summarized.

Structural and functional characterisation of Photosystem II from two His-tagged transplastomic strains of Nicotiana tabacum [PDF]

open access: yes, 2009
Photosystem II (PSII) is a polypeptide-cofactor complex organised as a homodimeric multisubunit protein embedded in the thylakoid membrane. PSII monomers are heterooligomers related to each other by a pseudo-twofold axis perpendicular to the membrane ...

Chloramphenicol mediates superoxide production in Photosystem II and enhances its photodamage in isolated membrane particles

open access: yesFrontiers in Plant Science, 2016
Chloramphenicol is an inhibitor of protein synthesis, which is frequently used to decouple photodamage and protein synthesis dependent repair of Photosystem II during the process of photoinhibition.

Ferredoxin and flavodoxin reduction by photosystem I [PDF]

open access: yes, 2001
Ferredoxin and flavodoxin are soluble proteins which are reduced by the terminal electron acceptors of photosystem I. The kinetics of ferredoxin (flavodoxin) photoreduction are discussed in detail, together with the last steps of intramolecular ...

Biochemical and biotechnological approaches as basis for structure determination of pigment-protein complexes of oxygenic photosynthesis [PDF]

open access: yes, 2009
Today the structure of photosystem II, which is the enzyme responsible for the evolution of molecular oxygen by plants, algae and cyanobacteria, is known up to a resolution of about 3.0 Å in cyanobacteria (Loll et al., 2005).

The effect of nicosulfuron and bentazon on photosynthetic performance of common cocklebur (Xanthium strumarium L.)

open access: yesEnvironmental and Sustainability Indicators, 2020
In order to evaluate the effects of bentazon and nicosulfuron on the photosynthetic apparatus of X. strumarium in greenhouse condition, chlorophyll a fluorescence (ChlF) method was studied at 1, 2, 3, and 4 days after herbicide treatment (DAHT). Bentazon

Dynamic plastid redox signals integrate gene expression and metabolism to induce distinct metabolic states in photosynthetic acclimation in Arabidopsis [PDF]

open access: yes, 2009
Plants possess acclimation responses in which structural reconfigurations adapt the photosynthetic apparatus to fluctuating illumination. Long-term acclimation involves changes in plastid and nuclear gene expression and is controlled by redox signals ...
