There is very little in this eleventh volume of Topics in Photosynthesis which could have been written when the first volume was published fifteen years ago. Advances over the last decade have been spectacular, most particularly in our understanding of the photosystems that is the subject of this volume. After a comparative introducution of bacterial and plant photosystems, the book begins with a consideration of what is theoretically possible in energy conversion. This is followed by light harvesting in photosystems II, followed by its molecular biology, protein engineering, thermoluminescence, photoinhibition, the effect of herbicides and heat shock, and, most important function of all and one about which so little is yet understood at the molecular level, the process by which it evolves oxygen. The last three chapters deal with the equivalent processes of photosystem I. The whole volume tells the story of a natural system of incredible ingenuity and complexity, but which as the chapters unfold, is seen to be within our grasp and eventual ability to comprehend.

Doctoral Thesis / Dissertation from the year 2010 in the subject Biology - Ecology, Tel Aviv University, language: English, abstract: Photosystem I (PSI) is a multi-subunit and intricate membrane super-complex of protein and non-protein components that catalyzes one of the first steps of oxygenic photosynthesis. PSI captures sunlight through a highly sophisticated pigment network and consequently converts the solar energy into its chemical form providing essential food and fuel to power life on the Earth. PSI operates with the unprecedented quantum efficiency of close to 100%. For this reason, it is regarded as the most efficient light capturing and energy conversion device in Nature. The ability of PSI to convert sunlight energy is highly dependent on the precise spatial arrangement of protein subunits and the relative positions of numerous cofactors. For this reason, we took the challenge of the crystallographic determination of plant PSI structure at a resolution that would allow estimation of single atoms and therefore enable positive identification of most of the amino acid and chlorophyll conformations. We solved the structure of the intact PSI at 3.3 Å resolution that revealed exquisitely organized 600 kDa complex of 18 protein subunits, with 46 transmembrane helices and total of 195 cofactors, comprising one of the most complicated membrane protein structures unraveled by the X-ray crystallography. The structure clarifies at almost atomic level how plant PSI links absorption of photons to production of chemical energy, according to the blueprints of protein-pigment network, and reveals working principles of photosynthetic antenna system. The three-dimensional description laid the foundation for further structural analysis that discusses how the biological significance of plant PSI is matched by its structural elements. For example, we analyzed the interactions of plant PSI with its electron donors and acceptors, highlighting the differences from its cyan

Photosystem II is a 700-kDa membrane-protein super-complex responsible for the light-driven splitting of water in oxygenic photosynthesis. The photosystem is comprised of two 350-kDa complexes each made of 20 different polypeptides and over 80 co-factors. While there have been major advances in understanding the mature structure of this photosystem many key protein factors involved in the assembly of the complex do not appear in the holoenzyme. The mechanism for assembling this super-complex is a very active area of research with newly discovered assembly factors and subcomplexes requiring characterization. Additionally the ability to split water is inseparable from light-induced photodamage that arises from radicals and reactive O2 species generated by Photosystem II chemistry. Consequently, to sustain water splitting, a “self repair” cycle has evolved whereby damaged protein is removed and replaced so as to extend the working life of the complex. Understanding how the biogenesis and repair processes are coordinated is among several important questions that remain to be answered. Other questions include: how and when are the inorganic cofactors inserted during the assembly and repair processes and how are the subcomplexes protected from photodamage during assembly? Evidence has also been obtained for Photosystem II biogenesis centers in cyanobacteria but do these also exist in plants? Do the molecular mechanisms associated with Photosystem II assembly shed fresh light on the assembly of other major energy-transducing complexes such as Photosystem I or the cytochrome b6/f complex or indeed other respiratory complexes? The contributions to this Frontiers in Plant Science Research Topic are likely to reveal new details applicable to the assembly of a range of membrane-protein complexes, including aspects of self-assembly and solar energy conversion that may be applied to artificial photosynthetic systems. In addition, a deeper understanding of Photosystem II assembly — particularly in response to changing environmental conditions — will provide new knowledge underpinning photosynthetic yields which may contribute to improved food production and long-term food security.

Structure and function of the components of the photosynthetic apparatus and the molecular biology of these components have become the dominant themes in advances in our understanding of the light reactions of oxygenic photosynthesis. Oxygenic Photosynthesis: The Light Reactions presents our current understanding of these reactions in thylakoid membranes. Topics covered include the photosystems, the cytochrome b6-f complex, plastocyanin, ferredoxin, FNR, light-harvesting complexes, and the coupling factor. Chapters are also devoted to the structure of thylakoid membranes, their lipid composition, and their biogenesis. Updates on the crystal structures of cytochrome f, ATP synthase and photosystem I are presented and a section on molecular biology and evolution of the photosynthetic apparatus is also included. The chapters in this book provide a comprehensive overview of photosynthetic reactions in eukaryotic thylakoids. The book is intended for a wide audience, including graduate students and researchers active in this field, as well as those individuals who have interests in plant biochemistry and molecular biology or plant physiology.

All biomass is derived from photosynthesis. This provides us with food fuel, as well as fibre. This process involves conversion of solar energy, via photochemical reactions, into chemical energy. In plants and cyanobacteria, carbon dioxide and water are converted into carbohydrates and oxygen. It is the best studied research area of plant biology. We expect that this area will assume much greater importance in the future in view of the depleting resources ofthe Earth's fuel supply. Furthermore, we believe that the next large increase in plant productivity will come from applications of the newer findings about photosynthetic process, especially through manipulation by genetic engineering. The current book covers an integrated range of subjects within the general field of photosynthesis. It is authored by international scientists from several countries (Australia, Canada, France, India, Israel, Japan, Netherlands, Russia, Spain, UK and USA). It begins with a discussion of the genetic potential and the expression of the chloroplast genome that is responsible for several key proteins involved in the electron transport processes leading to O evolution, proton release and the production of 2 NADPH and A TP, needed for CO fixation. The section on photosystems discusses 2 how photosystem I functions to produce NADPH and how photosystem II oxidizes water and releases protons through an "oxygen clock" and how intermediates between the two photosystems are produced involving a "two electron gate".
