The regulation of the phosphorylation/dephosphorylation process, resulting in "cellular switches" that monitor normal plant physiology, growth and development, has immense potential in crop systems. With much of the information in the nascent stages, coming largely from Arabidopsis and rice particularly, the use of cell biology, genetic screens, biochemical approaches aided by an omics approach should help unravel the detail functional information available about signaling pathways in plants. The regulation could be exploited to develop crop varieties better equipped to handle changing environments and enhance agricultural productivity. In the post-genomic era, one of the major challenges is investigation and understanding of multiple genes and gene families regulating a particular physiological and developmental aspect of plant life cycle. One of the important physiological processes is regulation of stress response, which leads to adaptation or adjustment in response to adverse stimuli. With the holistic understanding of the signaling pathways involving phosphatases, one gene family or multiple genes or gene families, plant biologist can lay a foundation for designing and generating future crops, which can withstand the higher degree of environmental stresses. Especially abiotic stresses, which are the major cause of crop loss throughout the world without losing crop yield and productivity. This book incorporates the contributions from leading plant biologists in the field of stress-mediated dephosphorylation by phosphatases as an important task to elucidate the aspects of stress signaling by functional genomic approaches.

Invasive species have inspired concern for many reasons, including economic and environmental impacts in specific jurisdictions within particular countries. However, it is apparent that for some invasive plant species, political borders offer only weak barriers because these species have succeeded in invading many countries, emerging as threats at a global level. With this level of threat, a number of books on invasive plants and invasive species in general have been published in recent years, but none explicitly provides "global" coverage, perhaps because it is only recently that the full geographical, economic and environmental implications of widespread spread and adaptive nature of these particular invasive plants have been recognized. We plan to make this volume unique by profiling plant invasions in explicitly geographical contexts; on the world continents (Chapters 5-11), as well as islands (Chapter 12) and mountains (Chapter 13). This global approach is supported by an overview of invasion biology and recent advances (Chapter 1) and how different communities differ in invasibility (Chapter 2). Global factors influencing invasion are introduced in Chapter 3 (globalized trade) and Chapter 4 (climate change). Key species are profiled through geographic treatments, continent by continent (Chapters 5-11), and for islands (Chapter 12) and mountains (Chapter 13). The impact of invasive plants is highlighted in Chapter 14, both in biotic and economic terms, partly to counter the tendency for the young field of invasion biology to rely too much on anecdotal evidence. This chapters is also designed to bring home the message that these are serious problems that must be dealt with, as covered in the subsequent chapters. The book concludes with three chapters casting light on solutions to the many problems described in the rest of the volume. Chapter 15 features new, innovative technologies that are being developed to monitor and manage invasive plants, and Chapter 16 presents comprehensive strategies for public education and implementation of management on local and global scales. Chapter 17 describes different future scenarios depending on current trends in plant invasion and its management, just as climate change predictions employ various scenarios to project the future. The future is very much up to us, as humanity grapples with the question of how best to strategically meet the problems of global invasive plant problems that we ourselves have created that is further challenged by a changing climate. We are confident that this book will be of interest to invasion biologists, resource managers, and the legion of others who must deal with these invasive plants across the globe on a daily basis.

Agriculture faces many challenges to fulfil the growing demand for sustainable food production and ensure high-quality nutrition for a rapidly growing population. To guarantee adequate food production, it is necessary to increase the yield per area of arable land. A method for achieving this goal has been the application of growth regulators to modulate plant growth. Plant growth regulators (PGRs) are substances in specific formulations which, when applied to plants or seeds, have the capacity to promote, inhibit, or modify physiological traits, development and/or stress responses. They maintain proper balance between source and sink for enhancing crop yield. PGRs are used to maximize productivity and quality, improve consistency in production, and overcome genetic and abiotic limitations to plant productivity. Suitable PGRs include hormones such as cytokinins and auxins, and hormone-like compounds such as mepiquat chloride and paclobutrazol. The use of PGRs in mainstream agriculture has steadily increased within the last 20 years as their benefits have become better understood by growers. Unfortunately, the growth of the PGR market may be constrained by a lack of innovation at a time when an increase in demand for new products will require steady innovation and discovery of novel, cost-competitive, specific, and effective PGRs. A plant bio-stimulant is any substance or microorganism applied to plants with the aim to enhance nutrition efficiency, abiotic stress tolerance and/or crop quality traits, regardless of its nutrients content. Apart from traditional PGRs, which are mostly plant hormones, there are a number of substances/molecules such as nitric oxide, methyl jasmonate, brassinosteroids, seaweed extracts, strigolactones, plant growth promoting rhizobacteria etc. which act as PGRs. These novel PGRs or bio-stimulants have been reported to play important roles in stress responses and adaptation. They can protect plants against various stresses, including water deficit, chilling and high temperatures, salinity and flooding. This book includes chapters ranging from sensing and signalling in plants to translational research. In addition, the cross-talk operative in plants in response to varied signals of biotic and abiotic nature is also presented. Ultimately the objective of this book is to present the current scenario and the future plan of action for the management of stresses through traditional as well as novel PGRs. We believe that this book will initiate and introduce readers to state-of-the-art developments and trends in this field of study.

Global industrial growth has resulted in numerous pollutants being introduced into the environment. It has additionally caused decreased water availability for agricultural activity in developing countries, which, in turn, has compelled farmers to use wastewater irrigation. In advanced agricultural systems, farmers are adapting various strategies to achieve a higher yield and thus sustain crop productivity. Consequent to the introduction of contaminants in the environment, soil pollutants have become a critical issue. Selection of disease-resistant, high-yielding crop varieties, and extensive fertilizer applications are quite common among farming communities. This book provides insight into environmental pollutants with special reference to their interference with plant nutrition. It additionally discusses the physiological aspects of plant nutrition. This book enhances current knowledge of the effects of pollutants on plant growth and physiology.

This book addresses the impact of important climatic changes on plant pests (including weeds, diseases and insect pests), and their interactions with crop plants. Anthropogenic activities have seriously impacted the global climate. As a result, carbon dioxide (CO2) and temperature levels of the earth are on a continuous rise. The global temperature is expected to increase by a 3 DegreesC or more by the end of this century. The CO2 concentration was below 300 parts per million (ppm) before the start of the industrial era; however, recently it has exceeded 400 ppm. This is highest ever in human history. Other than global warming and elevated CO2 concentrations, anthropogenic activities have also disturbed the global water cycle, ultimately, impacting the quantity and distribution of rainfall. This has resulted in drought conditions in many parts of the world. Global warming, elevated CO2 concentration and drought are considered the most important recent climatic changes that are impacting global ecosystems and human societies. Among other impacts, the effects of climatic changes on pests, pest-crop interactions and pest control are important with relevance to global food security, and hence require immediate attention by plant scientists. This book discusses innovative and the most effective pest control methods under an environment of changing climate and elaborates on the impact of drought on plant pests and their control.

Abiotic and biotic stress factors, including drought, salinity, waterlog, temperature extremes, mineral nutrients, heavy metals, plant diseases, nematodes, viruses, and diseases, adversely affect growth as well as yield of crop plants worldwide. Plant growth-promoting microorganisms (PGPM) are receiving increasing attention from agronomists and environmentalists as candidates to develop an effective, eco-friendly, and sustainable alternative to conventional agricultural (e.g., chemical fertilizers and pesticide) and remediation (e.g., chelators-enhanced phytoremediation) methods employed to deal with climate change-induced stresses. Recent studies have shown that plant growth-promoting bacteria (PGPB), rhizobia, arbuscular mycorrhizal fungi (AMF), cyanobacteria have great potentials in the management of various agricultural and environmental problems. This book provides current research of biofertilizers and the role of microorganisms in plant health, with specific emphasis on the mitigating strategies to combat plant stresses.

Selenium plays a significant role in preventing certain types of cancer and cardiovascular diseases. The level of Selenium in the human body depends on its concentration in food. In turn, the content in vegetable crops is a function of the soil-plant system. There are many countries in the world with low Selenium content in the soil. The average daily human intake is thus limited through food chain. Analysis of Selenium status suggests that fortification of the soil substrate with Sodium Selenate, and foliar application to agricultural crops are both effective means of Selenium enrichment. Our intention for this publication is to present the possibilities of augmenting Selenium content by biofortification of soils and plants through differentiated nutrition. In the first part of the monograph, the results of Selenium supplementation in model vegetation experiments are presented. The next part of the monograph presents the results of foliar supplementation of Selenium in field conditions. This book is an outstanding reference source for plant breeders and researchers engaged in biofortification of horticulture crops. It is also beneficial to agricultural companies and other stakeholders.

The population of the world continues to increase at an alarming rate. The trouble linked with overpopulation ranges from food and water scarcity to inadequacy of space for organisms. Overpopulation is also linked with several other demographic hazards, for instance, population blooming will not only result in exhaustion of natural repositories, but it will also induce intense pressure on the world economy. Today nanotechnology is often discussed as a key discipline of research but it has positive and negative aspects. Also, due to industrialization and ever-increasing population, nano-pollution has been an emerging topic among scientists for investigation and debate. Nanotechnology measures any substance on a macromolecular scale, molecular scale, and even atomic scale. More importantly, nanotechnology deals with the manipulation and control of any matter at the dimension of a single nanometer. Nanotechnology and nanoparticles (NPs) play important roles in sustainable development and environmental challenges as well. NPs possess both harmful and beneficial effects on the environment and its harboring components, such as microbes, plants, and humans. There are many beneficial impacts exerted by nanoparticles, however, including their role in the management of waste water and soil treatment, cosmetics, food packaging, agriculture, biomedicines, pharmaceuticals, renewable energies, and environmental remedies. Conversely, NPs also show some toxic effects on microbes, plants, as well as human beings. It has been reported that use of nanotechnological products leads to the more accumulation of NPs in soil and aquatic ecosystems, which may be detrimental for living organisms. Further, toxic effects of NPs on microbes, invertebrates, and aquatic organisms including algae, has been measured. Scientists have also reported on the negative impact of NPs on plants by discussing the delivery of NPs in plants. Additionally, scientists have also showed that NPs interact with plant cells, which results in alterations in growth, biological function, gene expression, and development. Thus, there has been much investigated and reported on NPs and plant interactions in the last decade. This book discusses the most recent work on NPs and plant interaction, which should be useful for scientists working in nanotechnology across a wide variety of disciplines.

Polyphagous pests are primarily agricultural pests that feed on economically important agricultural and horticultural crops of wide taxonomic diversity across the globe. They cause immense damage across different crop varieties owing to their generalist and voracious food habits. The advent of mono-crop culture in a huge area and the massive use of pesticides post green revolution have massively increased pest outbreaks all over the world. The Middle Eastern countries, African continent and even the Indian subcontinent is increasingly facing resurgences of polyphagus pests. This book compiles an inclusive account of polyphagous pests. It covers locusts, termites, aphids, whiteflies, mealybugs, scale insects, gram pod borer, fall armyworm, thrips, mites and rodents. The book discusses mode of spread, enormity of losses caused, mechanism of action, and also means to reduce the crop losses. It brings together a unique perspective for researchers to learn effective pest management practices across all crops. This book is a reference guide to researchers and also useful for academicians and students of entomology.

This book provides a detailed review of many different aspects of pathogens, from the effects of single base pair mutations to large-scale control options, bringing into a single volume over 100 years of findings from thousands of researchers worldwide.
