Photoprotection Photoinhibition Gene Regulation and Environment

This book was edited by three outstanding authorities in the areas of Photoprotection, Photoinhibition, Gene Regulation, and Environment: Barbara Demmig-Adams and William W. Adams III (both at the University of Colorado, Boulder, Colorado) and Autar K. Mattoo (Henry A. Wallace Beltsville Agricultural Research Center, Beltsville, Maryland).

The topic of the book, as provided by our 3 distinguished editors, is: "Photoprotection, Photoinhibition, Gene Regulation, and Environment"; it examines the processes whereby plants monitor environmental conditions and orchestrate their response to change, an ability paramount to the life of all plants. 'Excess light', absorbed by the light-harvesting systems of photosynthetic organisms, is an integrative indicator of the environment, communicating the presence of intense light and any conditions unfavorable for growth and photosynthesis. Key plant responses are photoprotection and photoinhibition. In this volume, the dual role of photoprotective responses in the preservation of leaf integrity and in redox signaling networks modulating stress acclimation, growth, and development is addressed. In addition, the still unresolved impact of photoinhibition on plant survival and productivity is discussed. Specific topics include dissipation of excess energy via thermal and other pathways, scavenging of reactive oxygen by antioxidants, proteins key to photoprotection and photoinhibition, peroxidation of lipids, as well as signaling by reactive oxygen, lipid-derived messengers, and other messengers that modulate gene expression. Approaches include biochemical, physiological, genetic, molecular, and field studies, addressing intense visible and ultraviolet light, winter conditions, nutrient deficiency, drought, and salinity. This book is directed toward advanced undergraduate students, graduate students, and researchers interested in Plant Ecology, Stress Physiology, Plant Biochemistry, Integrative Biology, and Photobiology."

"Photoprotection, Photoinhibition, Gene Regulation, and Environment' has 21 authoritative Chapters, and is authored by 57 international authorities from 16 countries. The book begins with three perspectives: Harry Yamamoto (USA) presents a random walk to and through the xanthophyll cycle (Chapter 1); Barry Osmond and Britta Forster (Australia) provide an account of Photoinhibition: then and now (Chapter 2); Marvin Edelman and Autar Mattoo (Israel and USA) discuss the past and future perspectives of the involvement of the D1 protein in photoinhibition (Chapter 3). These perspectives are followed by 18 chapters. In Chapter 4, Barbara Demmig-Adams, Volker Ebbert, Ryan Zarter and William Adams (USA) summarize characteristics and species-dependent employment of flexible versus sustained thermal dissipation and photoinhibition. Then, William Adams, C. Ryan Zarter, Kristine Mueh, Veronique Amiard and Barbara Demmig-Adams (USA) discuss details of energy dissipation and photoinhibition as a continuum of protection (Chapter 5). In Chapter 6, Fermín Morales, Anunciación Abadía and Javier Abadía (Spain) discuss photoinhibition and photoprotection under nutrient deficiencies, drought, and salinity. This is followed by a summary, by Donat-P. Hader (Germany), of photoinhibition and UV responses in the aquatic environment (Chapter 7); and a discussion, by Alexander V. Vener (Sweden), of phosphorylation of thylakoid proteins (Chapter 8). In Chapter 9, Hou-Sung Jung and Krishna K. Niyogi (USA) provide a molecular analysis of photoprotection of photosynthesis. Stefan Jansson (Sweden) discusses the saga of a protein family involved in light harvesting and photoprotection (Chapter 10). In Chapter 11, a team of 10 authors (Norman Huner, Alexander Ivanov, Prafullachandra Sane, Tessa Pocock, Marianna Krol, Andrius Balseris, Dominic Rosso, Leonid Savitch, Vaughan Hurry and Gunnar Oquist (Canada, Sweden and India) discuss the role of reaction center quenching versus antenna quenching in the photoprotection of Photosystem II. Then, Kittisak Yokthongwattana and Anastasios Melis (Thailand and USA) discuss, in Chapter 12, the mechanism of a Photosystem II damage and repair cycle involved in photoinhibition (and its recovery) in oxygenic photosynthesis. Subsequently, regulation by environmental conditions of the repair of Photosystem II in cyanobacteria is discussed by Yoshitaka Nishiyama, Suleyman Allakhverdiev and Norio Murata (Japan and Russia) in Chapter 13. Tsuyoshi Endo and Kozi Asada (Japan) provide, in Chapter 14, an understanding of the role of cyclic electron flow and the so-called water-water cycle in photoprotection, particularly around Photosystem I. This is followed by Chapter 15 on the integration of signaling in antioxidant defenses by Philip Mullineaux, Stanislaw Karpinski and Gary Creissen (UK and Sweden). Chapter 16, by Christine Foyer, Achim Trebst and Graham Noctor (UK, Germany and France), deals with signaling and integration of defense functions of tocopherol, ascorbate, and glutathione. Then, in Chapter 17, Sacha Baginsky and Gerhard Link (Switzerland and Germany) discuss redox regulation of chloroplast gene expression. Robert Larkin (USA) provides, in Chapter 18, a summary of intracellular signaling and chlorophyll synthesis. Nine authors (Karl-Josef Dietz, Tina Stork, Iris Finkemeier, Petra Lamkemeyer, Wen-Xue Li, Mohamed El-Tayeb, Klaus-Peter Michel, Elfriede Pistorius, and Margarete Baier), from Germany and Egypt, discuss, in Chapter 19, the role of per-oxiredoxins in oxygenic photosynthesis of cyanobac-teria and of higher plants and pose the question of the importance of peroxide detoxification or re-dox sensing in the process. Chapter 20, by Mauro Maccarrone (Italy), reviews lipoxygenases, apoptosis, and the role of antioxidants. The book ends appropriately with Chapter 21, by Christiane Reinbothe and Steffen Reinbothe (Germany and France), on the regulation of photosynthetic gene expression by the environment from the seedling de-etiolation stage to leaf senescence.
