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 ...

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Biochemische Charakterisierung von Photosystem-I-Komplexen aus Diatomeen

, 2009
Photosystem (PS) I is a huge membrane protein complex which coordinates around 200 co-factors. Upon light excitation a charge separation at the PS I reaction centre is induced which leads to an electron transport across the thylakoid membrane and the ...

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

, 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 ...

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.

Quality Control of Photosystem II [PDF]

Plant and Cell Physiology, 2001
Photosystem II is particularly vulnerable to excess light. When illuminated with strong visible light, the reaction center D1 protein is damaged by reactive oxygen molecules or by endogenous cationic radicals generated by photochemical reactions, which is followed by proteolytic degradation of the damaged D1 protein.

Effect of saline irrigation on Tetragonia tetragonioides (Pall.) Kuntze grown on different soil types under greenhouse conditions

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change and population growth are major challenges for sustainable food production, particularly in regions affected by water scarcity and soil salinization. In this context, halophytes represent promising candidates as alternative and sustainable food crops for salt‐affected areas.

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

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

EPJ 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 ...

Non-triazine photosystem II inhibitors provide effective control of metabolic atrazine-resistant Amaranthus tuberculatus. [PDF]

Pest Manag Sci
Metabolism‐based atrazine‐resistant Amaranthus tuberculatus populations ACR and MCR exhibit little or no cross‐resistance to amicarbazone and metribuzin, suggesting that non‐halogenated Group 5 herbicides can be utilized to re‐establish effective control.
