Role of Chitosan and Chitosan-Based Nanomaterials in Plant Sciences explores the physiological, morphological, biochemical and molecular regulation of chitosan and chitosan-based nanoparticles in plants in normal conditions, as well as during different stresses, and their probable mechanism of operation in the tolerance mechanism. The book stimulates further research in the field of chitosan and will foster further interests for researchers, academicians and scientists worldwide. Nanotechnology is being used widely in all disciplines of science and technology, including plant sciences. Chitosan has widely been reported as a beneficial organic compound for the growth and developments of plants and it plays a protective role for the plants against abiotic and biotic stresses. Yet there are very few books available that deal exclusively with Chitosan and Chitosan based nanoparticles impacts on plants respectively. Analyzes the research on chitosan and chitosan-based nanomaterials in plant sciences Includes the latest information on toxicity and human exposure Reviews modifications and alterations in plant expressions and biochemical pathways

Nanotechnology can target specific agricultural problems related to plant pathology and provide new techniques for crop disease control. Plant breeders and phytopathologists are needed who can apply nanogenomics and develop nanodiagnostic technologies to accurately advance the improvement process and take advantage of the potential of genomics. This book serves as a thorough guide for researchers working with nanotechnology to address plant protection problems. Novel nanobiotechnology methods describe new plant gene transfer tools that improve crop resistance against plant diseases and increase food security. Also, quantum dots (QDs) have emerged as essential tools for fast and accurate detection of particular biological markers. Biosensors, QDs, nanostructured platforms, nanoimaging, and nanopore DNA sequencing tools have the potential to raise sensitivity, specificity, and speed in pathogen detection, thereby facilitating high-throughput analysis and providing high-quality monitoring and crop protection. Also, this book deals with the application of nanotechnology for quicker, more cost-effective, and precise diagnostic procedures of plant diseases and mycotoxins. Applications of nanotechnology in plant pests and disease control, antimicrobial mechanisms, pesticides remediation and nanotoxicity on plant ecosystem and soil microbial communities are discussed in detail. Moreover, the application of specific nanomaterials including silver, copper, carbon- or polymer-based nanomaterials and nanoemulsions are also discussed. Crops treated with safe nanofertilizers and nanopesticides will gain added value because they are free of chemical residues, decay and putative pathogens for human health, sustaining the global demand for high product quality.

The emergence of nanotechnology and the development of new nanodevices and nanomaterials have opened up exciting opportunities for novel applications in agriculture and biotechnology. Nanotechnology has the potential to modernize agricultural research and practice, but although it has gained momentum in the agriculture sector over last decade, there are still knowledge gaps between scientific communities. This book presents a comprehensive overview of current developments in nanotechnology-based sustainable agriculture. Focusing on various aspects of nanotechnology in different sectors of agriculture, such as crop production, soil fertility management and crop improvement, it offers insights into the current trends and future prospects of nanotechnology, along with the benefits and risks and their impact on agricultural ecosystems. It also highlights the use of nanotechnology to reduce agrochemical usage, to increase nutrient uptake efficiency and to improve water and nutrient management, and the use of nano-biosensors to manage plant diseases. The book is a valuable reference resource for scientists, policymakers, students and researchers who are engaged in developing strategies to cope with current agricultural challenges.

This book discusses the latest developments in plant-mediated fabrication of metal and metal-oxide nanoparticles, and their characterization by using a variety of modern techniques. It explores in detail the application of nanoparticles in drug delivery, cancer treatment, catalysis, and as antimicrobial agent, antioxidant and the promoter of plant production and protection. Application of these nanoparticles in plant systems has started only recently and information is still scanty about their possible effects on plant growth and development. Accumulation and translocation of nanoparticles in plants, and the consequent growth response and stress modulation are not well understood. Plants exposed to these particles exhibit both positive and negative effects, depending on the concentration, size, and shape of the nanoparticles. The impact on plant growth and yield is often positive at lower concentrations and negative at higher ones. Exposure to some nanoparticles may improve the free-radical scavenging potential and antioxidant enzymatic activities in plants and alter the micro-RNAs expression that regulate the different morphological, physiological and metabolic processes in plant system, leading to improved plant growth and yields. The nanoparticles also carry out genetic reforms by efficient transfer of DNA or complete plastid genome into the respective plant genome due to their miniscule size and improved site-specific penetration. Moreover, controlled application of nanomaterials in the form of nanofertilizer offers a more synchronized nutrient fluidity with the uptake by the plant exposed, ensuring an increased nutrient availability. This book addresses these issues and many more. It covers fabrication of different/specific nanomaterials and their wide-range application in agriculture sector, encompassing the controlled release of nutrients, nutrient-use efficiency, genetic exchange, production of secondary metabolites, defense mechanisms, and the growth and productivity of plants exposed to different manufactured nanomaterials. The role of nanofertilizers and nano-biosensors for improving plant production and protection and the possible toxicities caused by certain nanomaterials, the aspects that are little explored by now, have also been generously elucidated.

Agriculture plays a vital role in our lives, providing food and economic benefits. Today, it faces severe challenges, due to decreasing arable land, depleting natural resources, changing climate pattern, and yet increasing demand for food. The recent introduction of nanotechnology in agriculture offers sustainable and precise solutions for developing smart agriculture practices and addressing the challenges faced by the ag-sector. Therefore, it is essential to understand this new science from a multidimensional perspective. Experts in the field have contributed in putting together this volume, covering topics like plant growth, protection and management using engineering nanoscale materials. The chapters in the book have been peer-reviewed and selected for publication based on independent reviewers’ reports. The book covers very specific, in-depth, and fundamental and applied aspects of the latest ag-nanotechnology research. It is hoped that each chapter of the book will be very useful for researchers, policy makers, and other audiences from interdisciplinary scientific subjects.
