Stress Responses Of Photosynthetic Organisms

Sixteen topics from the results of the research project "Molecular Mechanisms for Responses of the Photosynthetic Apparatus to the Environment," are documented in this excellent and timely work. Photosynthesis research has a long history in Japan, and many Japanese laboratories working in this field have been very active and productive. Based on the foundation established by these laboratories, the research reflected in this book focuses on elucidating the interactions between photosynthesis and the environment, with special emphasis on the molecular aspects of these interactions. The major purpose of the research was to identify specific genes required for (a) repair of the organisms from stress-induced damage to the photosynthetic machinery and (b) acclimation of photosynthetic processes to specific changes in environmental conditions. Once specific genes were identified, the effects of expression (and overexpression) of these genes in transgenic plants on acclimation processes were analyzed. Through the analysis of transgenic plants and cyanobacteria, the volume clarifies a number of molecular mechanisms by which plants acclimate to environmental variations, and the factors that govern recovery from stress-induced damage, especially with respect to the photosynthetic apparatus. A treatize on stress physiology and photosynthesis, the book also indicates the agricultural usefulness of transgenic plants and microalgae which are produced to study the molecular mechanisms of the tolerance of plants to changes in their environment.

This book explores the intricate mechanisms underlying the stress responses of phototrophs, which play a critical and foundational role in shaping and sustaining life on Earth. The photoautotrophic entities encounter a spectrum of natural and anthropogenic stresses, inducing a multitude of responses at the physiological, biochemical, genetic, and developmental levels. The comprehension of how these phototrophs adeptly counter stressors transcends mere scientific pursuit; it stands as an essential endeavor for predicting their adaptability in an ever-evolving world and, crucially, for conserving our delicate ecosystems. The book will shed light on the sophisticated interplay of stress signaling pathways and the nuanced engagement of stress-responsive hormones within these life forms. Furthermore, it unveils the cryptic genetic and epigenetic controls dictating stress-related gene expression, yielding profound insights into the enduring recollection of their responses to environmental challenges. This book is an essential read for researchers, educators, and students alike. It offers a comprehensive panorama of stress biology, unveiling the innermost mechanisms at play within photosynthetic organisms discussing their resilience and adaptation.

This collection discusses the variety of specific molecular reactions by means of which plants respond to physiological and toxic stress conditions. It focuses on the characterization of the molecular mechanisms that underlie the induction of toxicity and the triggered responses and resistances. The nine chapters, all written by prominent researchers, examine heavy metal toxicity, aluminum toxicity, arsenic toxicity, salt toxicity, drought stress, light stress, temperature stress, flood stress and UV-B stress. In addition, information on the fundamentals of stress responses and resistance mechanisms is provided. The book addresses researchers and students working in the fields of plant physiology and biochemistry.​

In order to survive, plants must respond effectively to severe alterations in environmental factors, such as ambient light, temperature and mineral or water availability. This book focuses on the various physiological, metabolic and molecular processes through which higher plants cope with dramatic changes in their ecosystems. It discusses both the short-term acclimation responses of individual plants and the long-term adaptations that ensure the survival of a species. Individual chapters in the text deal with the various organizational levels on which plants respond to different types of abiotic stress.

This new volume aims to be the single source that discusses in a comprehensive and elaborate way the photosynthetic and respiratory mechanisms in plants under hostile situations and the proper mitigating strategies to continue uninterrupted photosynthesis and respiration under such situations. Photosynthesis and respiration are the two main physiological processes for sugar biosynthesis and mobilization for driving all other vital functions. This volume delivers a wealth of sound information on these processes for scientists, researchers, and academicians. With chapters from renowned scientists, researchers, and global leaders, this volume focuses on the effect of environmental stressors on photosynthetic pigments, photosystems, activities of photosynthetic enzymes and protein complexes, PSII photochemistry, carbon fixation pathways, photosynthetic efficiency, glycolytic and Krebs cycle pathways, and ATP production and electron transport chain of plants. The recovery of photosynthesis and respiration through application of phytohormones, signaling molecules, and other protective agents are also emphasized. Genetic engineering to enhance photosynthetic efficiency is highlighted as well.

A guide to environmental fluctuations that examines photosynthesis under both controlled and stressed conditions Photosynthesis, Productivity and Environmental Stress is a much-needed guide that explores the topics related to photosynthesis (both terrestrial and aquatic) and puts the focus on the basic effect of environmental fluctuations. The authors—noted experts on the topic—discuss photosynthesis under both controlled and stressed conditions and review new techniques for mitigating stressors including methods such as transgeneics, proteomics, genomics, ionomics, metabolomics, micromics, and more. In order to feed our burgeoning world population, it is vital that we must increase food production. Photosynthesis is directly related to plant growth and crop production and any fluctuation in the photosynthetic activity imposes great threat to crop productivity. Due to the environmental fluctuations plants are often exposed to the different environmental stresses that cause decreased photosynthetic rate and problems in the plant growth and development. This important book addresses this topic and: Covers topics related to terrestrial and aquatic photosynthesis Highlights the basic effect of environmental fluctuations Explores common stressors such as drought, salinity, alkalinity, temperature, UV-radiations, oxygen deficiency, and more Contains methods and techniques for improving photosynthetic efficiency for greater crop yield Written for biologists and environmentalists, Photosynthesis, Productivity and Environmental Stress offers an overview of the stressors affecting photosynthesis and includes possible solutions for improved crop production.
