Molecular mechanisms of photosynthesis
This chapter discusses the organization and structure of Photosynthetic Systems, as well as the history and development of Photosynthesis, and the origins and evolution of photosynthesis.
The Physcomitrella Genome Reveals Evolutionary Insights into the Conquest of Land by Plants
This comparison reveals genomic changes concomitant with the evolutionary movement to land, including a general increase in gene family complexity; loss of genes associated with aquatic environments; acquisition of genes for tolerating terrestrial stresses; and the development of the auxin and abscisic acid signaling pathways for coordinating multicellular growth and dehydration response.
The natural history of nitrogen fixation.
The complex genetic history of the nitrogenase family is explored, which is replete with gene duplication, recruitment, fusion, and horizontal gene transfer and is discussed in light of the hypothesized presence of nitrogenase in the last common ancestor of modern organisms.
Evidence for wavelike energy transfer through quantum coherence in photosynthetic systems
Previous two-dimensional electronic spectroscopy investigations of the FMO bacteriochlorophyll complex are extended, and direct evidence is obtained for remarkably long-lived electronic quantum coherence playing an important part in energy transfer processes within this system is obtained.
Antenna Complexes from Green Photosynthetic Bacteria
Green photosynthetic bacteria contain unique peripheral antenna complexes known as chiorosomes, which are thought to protect the cell from light-induced superoxide formation under conditions of transient oxygen exposure.
Contribution of Aerobic Photoheterotrophic Bacteria to the Carbon Cycle in the Ocean
The vertical distribution of bacteriochlorophylla, the numbers of infrared fluorescent cells, and the variable fluorescence signal at 880 nanometers wavelength, all indicate that photosynthetically
Early Evolution of Photosynthesis1
An understanding of the origin and evolution of photosynthesis is of substantial interest, as it may help to explain inefficiencies in the solar energy storage process.
Spectral signatures of photosynthesis. I. Review of Earth organisms.
The "near-infrared (NIR) end" of the red edge to trend from blue-shifted to reddest for snow algae, temperate algae, lichens, mosses, aquatic plants, and finally terrestrial vascular plants is found.
Comparing Photosynthetic and Photovoltaic Efficiencies and Recognizing the Potential for Improvement
Natural photosynthesis is compared with present technologies for photovoltaic-driven electrolysis of water to produce hydrogen and opportunities in which the frontiers of synthetic biology might be used to enhance natural photosynthesis for improved solar energy conversion efficiency are considered.
Spectral signatures of photosynthesis. II. Coevolution with other stars and the atmosphere on extrasolar worlds.
M star planets could be a half to a tenth as productive as Earth in the visible, but exceed Earth if useful photons extend to 1.1 microm for anoxygenic photosynthesis, and under water, organisms would still be able to survive ultraviolet flares from young M stars and acquire adequate light for growth.
