The study of air pollution effects on vegetation has made rapid progress in the last five years. Growing concerns about effects of future increases in temperature and carbon dioxide (C0 ) levels on plant life have altered 2 the perspective of plant biologists in the field of pollutant-plant inter actions. In many cases, it is anticipated that crops and trees will increasingly experience multiple stresses in an altered environment: an environment in which physiological processes will no longer be matched to climate. Because of this problem, a major part of the focus of the air pollution effects research has shifted since 1987. Moreover, recent advances in our understanding of plant metabolic and molecular responses to stress have made it clear that many abiotic stresses elicit similar fundamental mechanisms. Adaptation responses to drought, extremes of temperature, xenobiotics and air pollutants are now known to involve the response of both specific and common resistance mechanisms, which often include altered gene expression. The field of air pollution effects on vegetation has benefitted greatly from this unification since results obtained and advances made in allied fields are now directly relevant. The advent of molecular genetics has made possible the production of transgenic plants containing altered amounts of resistance gene products which enables the posing of experimental questions which could not be addressed only five years ago. Hypotheses concerning the relevance of specific metabolites and processes to known responses to air pollution stress can now be tested.

Plant Responses to the Environment covers the fundamental mechanisms of plant responses to biotic and abiotic environmental stimuli. By combining established disciplines like physiology and genetics with new approaches stemming from molecular biology and biophysics, a new synthesis is achieved. For example, this book deals with the effects of microgravity on plant development, and it provides an extensive analysis of plant perception and response to low oxygen and high ozone. New techniques such as those used for gene transfer using the biolistic gene gun approach in soybeans are described. Other topics considered include systemic acquired resistance (SAR) in plants and recent advances in understanding how legume roots perceive bacterial lipooligosaccharide signals. A glossary, subject index, and author index are also provided. Plant Responses to the Environment will be a valuable reference for plant physiologists, ecophysiologists, agronomists, plant molecular biologists, experimental botanists, and other researchers interested in the topic.

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.

This second of a two-part treatise describes the phenomena of plants under stress, describing the relationship between plant structure, development, and growth and such environmental stresses as too much or too little water, light, heat, or cold.

Plant Life under Changing Environment: Responses and Management presents the latest insights, reflecting the significant progress that has been made in understanding plant responses to various changing environmental impacts, as well as strategies for alleviating their adverse effects, including abiotic stresses. Growing from a focus on plants and their ability to respond, adapt, and survive, Plant Life under Changing Environment: Responses and Management addresses options for mitigating those responses to ensure maximum health and growth. Researchers and advanced students in environmental sciences, plant ecophysiology, biochemistry, molecular biology, nano-pollution climate change, and soil pollution will find this an important foundational resource. Covers both responses and adaptation of plants to altered environmental states Illustrates the current impact of climate change on plant productivity, along with mitigation strategies Includes transcriptomic, proteomic, metabolomic and ionomic approaches
