A new study sheds new light on the evolution of photosynthesis in plants and algae, which could help to improve crop production.
Artificial photosynthesis has the potential to be one of the most promising sciences and technologies for solving the global environmental problems that may threaten the sustainability of humanity, ca...
Identification of a gene needed to expand light harvesting in photosynthesis into the far-red-light spectrum provides clues to the development of oxygen-producing photosynthesis, an evolutionary advan...
The quantum yield of the initial charge separation steps in bacterial photosynthetic reaction centers has been shown to be reduced in an applied electric field [Part I, Lao et al., J. Phys. Chem. 97 (...
The effect of an applied electric field has been measured for the quantum yield of formation of the P[sup +]H[sup [minus]], P[sup +]Q[sub A][sup [minus]], and [sup 3]P states of nonoriented Rb. sphaer...
The fluorescence intensity from randomly oriented, immobilized Rb. sphaeroides reaction centers at 77 K increases in the presence of an externally applied electric field. We have proposed that this in...
The triplet state of the primary electron donor is formed in bacterial reaction centers when electron transfer to the quinone is blocked. The relative quantum yield of formation and the rate of decay ...
Photosynthesis involves a very large number of photochemical and chemical transformations. This review focuses on the extraordinarily rapid transport of excitation energy in the antenna pigmentprotein...
A series of covalently linked dimers and trimers of chlorophyllide derivatives was investigated by time-resolved absorption and fluorescence spectroscopy (3-lo4 ps). For these compounds, the freeenerg...
By sequencing its genome, scientists are homing in on the genes and genetic pathways that allow the juicy pineapple plant to thrive in water-limited environments. The new findings, reported in the jou...
Photosynthesis leaves behind a unique calling card, a chemical signature that is spelled out with stable oxygen isotopes, according to a new study in Science. The findings suggest that similar isotopi...
20 August 2014 — Bacteria that grow in environments enriched in far-red light use a previously unknown process for harvesting energy. This discovery lays the foundation for further research aimed at i...
The team used a computer model to simulate how adding genes from a type of photosynthetic algae known as cyanobacteria might influence photosynthetic efficiency in plants. Cyanobacteria contain small ...
An international team of researchers, led by scientists at Virginia Tech and the University of California, Berkeley, has discovered that a process that turns on photosynthesis in plants likely develop...
During the 2010–2011 ‘Impacts of Climate Change on the EcoSystems and Chemistry of the Arctic Pacific Environment’ project, we measured photosynthetic parameters in natural Arctic phytoplankton assem...
