Download or read book Photophysiology written by Arthur C. Giese and published by Elsevier. This book was released on 2013-09-25 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photophysiology: Current Topics in Photobiology and Photochemistry, Volume VI is a collection of papers that discusses photobiological phenomena found on cells of organisms. The papers in this collection deal with specialized areas of photobiology. One paper describes the instruments used in measuring the course of chlorophyll fluorescence in vivo that occurs when a chlorophyll molecule, stimulated by a light source, returns to its ground state from a previous first singlet state, resulting in a light emission lasting for a few nanoseconds. Another paper discusses the mechanism of light-induced carotenoid synthesis in nonphotosynthetic plants, including temperature-independent photochemical reactions, which results in the organism's producing carotenoids on subsequent incubations in darkness. One paper also explains photosensitization observed in mutant cells resulting from exposure to specific wavelength of light in the presence of a natural sensitizer. This paper points out that there are four main groups of photosensitizers, namely, the hypericins, chlorophylls, porphyrins, and psoralens. This book can prove valuable for cell biologists, micro-biologists, students, and researchers involved in the fields of photobiology and photochemistry.

Available in PDF, EPUB and Kindle. Book excerpt: Light and Plant Development presents the Proceedings of the 22nd University of Nottingham Easter School in Agricultural Science. It discusses the spectral sensitivity of inhibition of flowering by light. It addresses the action spectrum for leaf enlargement and stem growth inhibition. Some of the topics covered in the book are the nature of the blue light photoreceptor in higher plants and fungi; re-examination of photochemical properties and absorption characteristics of phytochrome using high-molecular-weight preparations; and intermediates in the photoconversion of phytochrome. The high irradiance reaction is fully covered. The physiological evidence and localised responses, intracellular localisation and action of phytochrome are discussed in detail. The text describes in depth the immunological visualisation of phytochrome. The fractionation procedures and terminology are presented completely. A chapter is devoted to the photocontrol of enzyme levels. Another section focuses on the ribosomal RNA synthesis in developing leaves. The book can provide useful information to botanists, chemists, students, and researchers.
Download or read book Plant Physiology Development and Metabolism written by Satish C Bhatla and published by Springer. This book was released on 2018-11-28 with total page 1251 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the fundamentals of plant physiology for undergraduate and graduate students. It consists of 34 chapters divided into five major units. Unit I discusses the unique mechanisms of water and ion transport, while Unit II describes the various metabolic events essential for plant development that result from plants’ ability to capture photons from sunlight, to convert inorganic forms of nutrition to organic forms and to synthesize high energy molecules, such as ATP. Light signal perception and transduction works in perfect coordination with a wide variety of plant growth regulators in regulating various plant developmental processes, and these aspects are explored in Unit III. Unit IV investigates plants’ various structural and biochemical adaptive mechanisms to enable them to survive under a wide variety of abiotic stress conditions (salt, temperature, flooding, drought), pathogen and herbivore attack (biotic interactions). Lastly, Unit V addresses the large number of secondary metabolites produced by plants that are medicinally important for mankind and their applications in biotechnology and agriculture. Each topic is supported by illustrations, tables and information boxes, and a glossary of important terms in plant physiology is provided at the end.

Book excerpt: The Ozone Layer contains the proceedings of the Meeting of Experts on the Ozone Layer, organized by the United Nations Environment Programme and held in Washington, DC, on March 1-9, 1977. The papers review all aspects of the ozone layer, including the potential impact of stratospheric pollution and a reduction in the ozone layer on mankind, and encompass fields ranging from stratopheric physics and chemistry to biology, ecology, trade, and economics. This book is comprised of 23 papers and begins with a discussion on the environmental aspects of stratospheric ozone depletion and the effects of changing levels of ultraviolet radiation on phytoplankton, plants, timber production, and human health. Subsequent chapters explore some economic and social implications of a possible ban on the use of fluorocarbons; the link between atmospheric exchange processes and the ozone problem; and industry-sponsored studies on the effects of chlorofluorocarbons on the concentration of atmospheric ozone. The remaining chapters focus on stratospheric and ozone research activities in countries such as Canada, Germany, Italy, the Netherlands, United Kingdom, and the United States. This monograph will be a valuable resource for environmental scientists and policymakers.

Download or read book Light in Biology and Medicine written by Ron H. Douglas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost all life depends on light for its survival. It is the ultimate basis for the food we eat (photosynthesis), and many organisms make use of it in basic sensory mechanisms for guiding their behaviour, be it through the complex process of vision, or by the relatively more simple photosens itivity of microorganis~urthermore, light has profound implications for the field of medicine, both as a cause of disease (ie UV damage of DNA), and as a therapeutic agent (ie photodynamic therapy). These and other processes are the basis for the science of photobiolog~ which could be defined as the study of the effects of (visible and ultraviolet) light (from both the sun and artificial sources) on living matter. By its very nature, therefore, it is a multidisciplinary science involving branches of biology, chemistry, physics and medicine. This book contains a selection of papers which have been chosen to highlight recent advances in the various disciplines that make up photo biology. Although no book on photobiology can hope to be comprehensive, we hope that this volume includes a representative sample of much of what is new in the field. It is, however, inevitable that some areas will be better represented than others reflecting the biases of conference org anisers and editors.
Download or read book Blue Light Effects in Biological Systems written by H. Senger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four years ago The Blue Light Syndrome was published as the Proceed ings of the 1 st International Conference on the Effect of Blue Light in Plants and Microorganisms. Subsequently the interest in this fascinating and growing field of re search has further increased, as is reflected by numerous publications. Blue light effects cover such a wide spectrum of organisms, responses and methods that communication among scientists with backgrounds in biology, biochemistry, and biophysics is particularly necessary. These facts not only justified, but demanded calling the "Blue Light Family" together again. In spite of many fmancial problems, the second confer ence attracted 113 active members from 19 countries. The 2nd International Conference on The Effect of Blue Light in Plants and Microorganisms was held in July 1984, like the first at the University of Marburg. The organizer could again rely on the help of the International Advisory Committee (W. Briggs, Stanford; M. Furuya, Tokyo; J. Gressel, Rehovot; S. Miyachi, Tokyo; W. Rau, Miinchen; J. Schiff, Waltham; P .-S. Song, Lubbock). The very generous financial as sistance from the DFG and the support of the Philipps-Universitat Mar burg and its Sonderforschungsbereich "Zellenergetik and Zelldifferen zierung" were the prerequisites to organizing the conference. The present book consists of 56 original papers. The partitioning into eight chapters is always a problem. The grouping of different aspects of the papers into these chapters has not always been obvious, so that one or the other contribution could possibly fit in another chapter.
