Photosynthetic antenna-reaction-center mimicry
… and performances in terms of an artificial photosynthetic model are evaluated by electrochemical, computational, time resolved emission, and transient absorption spectral studies. The systems studied reveal their potential in transferring excitation energy and yielding long-lived charge …

Photosynthetic electron transport in cyanobacteria
… cyanobacteria and prochlorophytes have a similar photosynthetic apparatus. The light-driven reactions take place in the thylakoid membranes and three major membrane-intrinsic protein complexes carry out photosynthetic electron transfer, photosystem II, the cytochrome bf complex and photosystem I. …

Quantum Physics of Photosynthetic Light -Harvesting
… and transfer of electronic excitation to the photosynthetic reaction center (RC) constitutes the primary step of photosynthesis, i.e., the light harvesting process. A model for an atomic level structure of a so-called photosynthetic unit of the photosynthetic bacterium Rhodobacter sphaeroides …

Photovoltaic devices using photosynthetic protein complexes
Photosynthetic proteins have been used as an active material in design of organic solar cells. Traditional organic solar cells have the limitation of not being able to absorb light in the visible-NIR region of the solar spectrum. This region corresponds to over 70% power of the total solar …

Influence of photosynthetic inhibitors on peach
Several photosynthetic inhibitors were screened for relative photosynthetic reduction on leaves of greenhouse-grown peach trees. The most effective were 8% Vapor Gard, 10M diurcn, 10⁻³M ABA, and 10⁻³M terbacil, all of which reduced net photosynthesis (Pn) rates by 50% or more by 1 day after …

Synthetic Analogs of the Photosynthetic Reaction Center
The bis(porphyrin) subunit has also been incorporated into a triad complex where the bridge between the expected quinone and bis(porphyrin) subunit is a monomer porphyrin. Use of meso-(mesityl) dipyrromethane leads to trans-substituted porphyrin.

Heterogeneous Ultrafast Energy Transfer in Photosynthetic Proteins
… because whether energy transfer rates in photosynthetic proteins actually vary and, if so, by how much has not been measured. Previous experiments to measure rates relied on ensemble ultrafast spectroscopy, which is limited to average values. With single-molecule approaches, we can …

SOLAR ENERGY HARVESTING WITH PHOTOSYNTHETIC PIGMENT-PROTEIN COMPLEXES
… life on earth. Central to this process are the photosynthetic pigment-protein complexes that transduce sunlight into biologically useful forms of energy through a photochemical charge separation that has a quantum efficiency close to 100%. Integrating these natural pigment-protein complexes in …

Enhancing photosynthetic capacity and energy conversion in wheat
… wheat plants. No improvement was observed for photosynthetic traits or yield in the transgenic plants when compared to control plants, although unforeseen experimental problems could have hidden the expected phenotype. The achievements of this research contribute to improve the knowledge of …

Investigating Cytochromes in Photosynthetic Electron Transport in Cyanobacteria
Inhibitor binding sites in the cytochrome bf complex of Synechococcus 7002 was modified by site-directed mutagenesis. The aim of this study was to identify the amino acid residues in cytochrome b6 that participate in plastoquinol and inhibitor binding at the plastoquinol oxidation site of the …

Capturing Photosynthetic Traits from the Progenitors of Wheat
Bottlenecks exist in raising wheat yield, which are associated with the constriction of available genetic diversity in the modern wheat gene pool and difficulties in improving photosynthesis during the growing season. Using a range of phenotyping techniques including portable infrared gas …
