The knowledge of plant responses to various abiotic stresses is crucial to understand their underlying mechanisms as well as the methods to develop new varieties of crops, which are better suited to the environment they are grown in. Environmental Stress Physiology of Plants and Crop Productivity provides readers a timely update on the knowledge about plant responses to a variety of stresses such as salinity, temperature, drought, oxidative stress and mineral deficiencies. Chapters focus on biochemical mechanisms identified in plants crucial to adapting to specific abiotic stressors along with the methods of improving plant tolerance. The book also sheds light on plant secondary metabolites such as phenylpropanoids and plant growth regulators in ameliorating the stressful conditions in plants. Additional chapters present an overview of applications of genomics, proteomics and metabolomics (including CRISPR/CAS techniques) to develop abiotic stress tolerant crops. The editors have also provided detailed references for extended reading to support the information in the book. Environmental Stress Physiology of Plants and Crop Productivity is an informative reference for scholars and researchers working in the field of botany, agriculture, crop science and physiology, soil science, and environmental sciences.

The genetic modification of crops continues to be the subject of intense debate, and opinions are often strongly polarised. Environmental Impact of Genetically Modified Crops addresses the major concerns of scientists, policy makers, environmental lobby groups and the general public regarding this controversial issue, from an editorially neutral standpoint. While the main focus is on environmental impact, food safety issues, for both humans and animals are also considered. The book concludes with a discussion on the future of agricultural biotechnology in the context of sustainability, natural resource management and future global population and food supply.

Air pollution is ubiquitous in industrialized societies, causing a host of environmental problems. It is thus essential to monitor and reduce pollution levels. A number of plant species already are being exploited as detectors (for phytomonitoring) and as scavengers (for phytoremediation) of air pollutants. With advances in biotechnology, it is now feasible to modify plants for a wider range of phytomonitoring and phytoremediation applications. Air Pollution and Plant Biotechnology presents recent results in this field, including plant responses during phytomonitoring, pollution-resistant plant species, imaging diagnosis of plant responses, and the use of novel transgenic plants, along with reviews of basic plant physiology and biochemistry where appropriate. Researchers and students working in plant biotechnology and the environmental sciences or considering new areas of investigation will find this volume a valuable reference.

Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.

Plant growth and productivity are limited in many areas of the world by a wide variety of environmental stresses. This book discusses progress made toward the major goal of uncovering the plant resistance mechanisms to biotic and abiotic stresses; the purpose being to utilise this knowledge in genetic modification of plants for achieving improved stress resistance. This volume achieves a new synthesis in considering the mechanisms of resistance at various levels of organisation -- from individual cells and tissues, through whole plants, to communities. Chapters are written by internationally acknowledged experts, who have a wealth of research and teaching experience. With comprehensive and up-to-date coverage, this book analyses many outstanding problems and poses important questions for future research.

Environmental pollution as a consequence of diverse human activities has become a global concern. Urbanization, mining, industrial revolution, burning of fossil fuels/firewood and poor agricultural practices, in addition to improper dumping of waste products, are largely responsible for the undesirable change in the environment composition. Environmental pollution is mainly classified as air pollution, water pollution, land pollution, noise pollution, thermal pollution, light pollution, and plastic pollution. Nowadays, it has been realized that with the increasing environmental pollution, impurities may accumulate in plants, which are required for basic human uses such as for food, clothing, medicine, and so on. Environmental pollution has tremendous impacts on phenological events, structural patterns, physiological phenomena, biochemical status, and the cellular and molecular features of plants. Exposure to environmental pollution induces acute or chronic injury depending on the pollutant concentration, exposure duration, season and plant species. Moreover, the global rise of greenhouse gases such as carbon monoxide, carbon dioxide, nitrous oxides, methane, chlorofluorocarbons and ozone in the atmosphere is among the major threats to the biodiversity. They have also shown visible impacts on life cycles and distribution of various plant species. Anthropogenic activities, including the fossil-fuel combustion in particular, are responsible for steady increases in the atmospheric greenhouse gases concentrations. This phenomenon accelerates the global heating. Studies have suggested that the changes in carbon dioxide concentrations, rainfall and temperature have greatly influenced the plant physiological and metabolic activities including the formation of biologically active ingredients. Taken together, plants interact with pollutants, and cause adverse ecological and economic outcomes. Therefore, plant response to pollutants requires more investigation in terms of damage detection, adaptation, tolerance, and the physiological and molecular responses. The complex interplay among other emerging pollutants, namely, radioisotopes, cell-phone radiation, nanoparticles, nanocomposites, heavy metals etc. and their impact on plant adaptation strategies, and possibility to recover, mitigation, phytoremediation, etc., also needs to be explored. Further, it is necessary to elucidate better the process of the pollutant's uptake by plant and accumulation in the food chain, and the plant resistance capability against the various kinds of environmental pollutants. In this context, the identification of tolerance mechanisms in plants against pollutants can help in developing eco-friendly technologies, which requires molecular approaches to increase plant tolerance to pollutants, such as plant transformation and genetic modifications. Pollutant-induced overproduction of reactive oxygen species that cause DNA damage and apoptosis-related alterations, has also been examined. They also trigger changes at the levels of transcriptome, proteome, and metabolome, which has been discussed in this book.

Scientists agree that exposure to toxic agents in the environment can cause neurological and psychiatric illnesses ranging from headaches and depression to syndromes resembling parkinsonism. It can even result in death at high exposure levels. The emergence of subclinical neurotoxicity-the concept that long-term impairments can escape clinical detection-makes the need for risk assessment even more critical. This volume paves the way toward definitive solutions, presenting the current consensus on risk assessment and environmental toxicants and offering specific recommendations. The book covers: The biologic basis of neurotoxicity. Progress in the application of biologic markers. Reviews of a wide range of in vitro and in vivo testing techniques. The use of surveillance and epidemiology to identify neurotoxic hazards that escape premarket screening. Research needs. This volume will be an important resource for policymakers, health specialists, researchers, and students.
