Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Nanomaterials and Plant Potential written by Azamal Husen and published by Springer. This book was released on 2019-03-01 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Molecular Impacts of Nanoparticles on Plants and Algae covers molecular mechanisms of plants/algae related to cellular uptake and translocation of nanoparticles, and genome, transcriptome, proteome, and metabolome responses against it. The book introduces readers to state-of-the-art developments and trends of nanoparticles and plants/algae including interaction of nanoparticles with biological compounds in vitro. Nanoscience and nanotechnology have rapidly been developed in the last few decades, and they have a wide range of applications in industry, medicine, food, and agriculture. In agriculture, nanoparticles (NPs) have successfully been used for growth regulation, crop protection and improvement. They are also employed to cope with plant nutrient deficiencies. A predicted significant increase in the output of NPs will cause the discharge of a remarkable number of NPs to ecosystems, creating a need to understand how to optimize or mitigate their impact depending on their potential impact. These include serious health concerns for living organisms in aquatic, terrestrial, and atmospheric environments as well as human health through their potential existence in plant-based foods. The impact of NPs on living organisms including plants and algae, and uptake, translocation and molecular response mechanisms should be carefully considered before producing and using nanoparticles in large amounts as NPs, when entered to the body, induce changes in gene expressions related to the photosystem, water transport, cell wall formation, and cell division.

Download or read book Plant Response to Silver Nanoparticles written by Azamal Husen and published by Springer. This book was released on 2024-11-21 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book looks at the plant response to silver nanoparticles (Ag-NPs), which showed both beneficial and harmful effects in a plant system. These responses of Ag-NPs are primarily dependent on the concentration, plant species or cultivars, exposure time, shape, and size of NPs. In general, lower concentrations of Ag-NPs increase seed germination, rate of photosynthesis, and overall growth, but at higher concentrations, all these responses are declined in many plant species. Moreover, Ag-NPs at higher concentration induce stress and or phytotoxicity and produce reactive oxygen species which leads to the disruption of cellular metabolism. Ag-NPs exposure increased the number of chromosomal aberrations, micronuclei, and decreased the mitotic index in plant root tip cells. Proteomic study has shown that the exposure Ag-NPs resulted in an accumulation of protein precursors, indicative of the dissipation of a proton motive force. Ag-NPs also influence transcription of flowering key genes and thus delayed flowering time. A beneficial role of arbuscular mycorrhizal fungi in influencing the effects of Ag-NPs on plant-microbe systems in a soil matrix has been also examined. Beside the terrestrial plants, these particles have also influenced the growth of some wetland and aquatic plants, which are covered in this book. This book provides valuable information to scientists, researchers, and students, working specially on plant biology, plant nanobiotechnology, plant biochemistry, plant microbiology, agricultural and other allied subjects and or science.

Download or read book Plant Abiotic Stress Tolerance written by Mirza Hasanuzzaman and published by Springer. This book was released on 2019-04-04 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants have to manage a series of environmental stresses throughout their entire lifespan. Among these, abiotic stress is the most detrimental; one that is responsible for nearly 50% of crop yield reduction and appears to be a potential threat to global food security in coming decades. Plant growth and development reduces drastically due to adverse effects of abiotic stresses. It has been estimated that crop can exhibit only 30% of their genetic potentiality under abiotic stress condition. So, this is a fundamental need to understand the stress responses to facilitate breeders to develop stress resistant and stress tolerant cultivars along with good management practices to withstand abiotic stresses. Also, a holistic approach to understanding the molecular and biochemical interactions of plants is important to implement the knowledge of resistance mechanisms under abiotic stresses. Agronomic practices like selecting cultivars that is tolerant to wide range of climatic condition, planting date, irrigation scheduling, fertilizer management could be some of the effective short-term adaptive tools to fight against abiotic stresses. In addition, “system biology” and “omics approaches” in recent studies offer a long-term opportunity at the molecular level in dealing with abiotic stresses. The genetic approach, for example, selection and identification of major conditioning genes by linkage mapping and quantitative trait loci (QTL), production of mutant genes and transgenic introduction of novel genes, has imparted some tolerant characteristics in crop varieties from their wild ancestors. Recently research has revealed the interactions between micro-RNAs (miRNAs) and plant stress responses exposed to salinity, freezing stress and dehydration. Accordingly transgenic approaches to generate stress-tolerant plant are one of the most interesting researches to date. This book presents the recent development of agronomic and molecular approaches in conferring plant abiotic stress tolerance in an organized way. The present volume will be of great interest among research students and teaching community, and can also be used as reference material by professional researchers.

Download or read book Plant Response to Gold Nanoparticles written by Azamal Husen and published by Springer. This book was released on 2024-11-21 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, overall plant and soil system are examined exclusively in terms of gold nanoparticles (Au-NPs) exposure. Au-NPs influence plant growth and yield performance. They also affect plant and soil system interactions. Au-NPs responses are primarily depends on the concentration, plant species or cultivars, exposure time, shape and size of NPs. Investigation have shown that the lower concentrations of Au-NPs increase seed germination, beneficial biochemical components, rate of photosynthesis, and overall growth, however, at higher concentrations, all these responses are declined in different plant species. At higher concentration, Au-NPs induce stress in plant, create phytotoxicity and produce reactive oxygen species which leads to the disruption of cellular metabolism. Further, at higher concentration, Au-NPs hampered the physico-chemical process of plant and soil system. Moreover, the molecular and physiological performance showed that the exposure of Au-NPs resulted in oxidative stress and induced antioxidative and defense responses. The energy production related to metabolic pathways were also influenced by Au-NPs exposure. Au-NPs exposure accelerated the number of chromosomal aberrations, micronuclei, and decreased the mitotic index in plant root tip cells. Proteomic study has shown that the exposure Au-NPs resulted in an accumulation of protein precursors, indicative of the dissipation of a proton motive force. Au ions were noticed in roots and shoots, while Au-NPs were absorbed only in the plant root tissues. Au-NPs exposure also influence flowering process and seed germination. Beside the terrestrial plants, these particles have also influenced the growth of some wetland and aquatic plants. It was also noticed that the addition of Au-NPs into the culture medium had also influence the in vitro development and multiplication of plants. Studies have begun to examine how arbuscular mycorrhizal fungi might affect the uptake of specific nanoparticles include Au and how these particles might influence the plant-mycorrhizal relationships. The impact of Au-NPs on the size and structure of microbial communities in soil; and soil enzymatic activities for β-glucosidase, urease, alkaline phosphatase, and dehydrogenase has been examined. In the present book, environmental safety, and ethical issues related to use of Au-NPs in plant and soil system has been also explored. Overall, this book is provide an up to date, most important and selected information associated with the plant response to Au-NPs. This book will be a good resource for upper-level students, faculty, scientists, and researchers working specially on plant biology, plant nanobiotechnology, plant biochemistry, plant microbiology, agricultural and other allied subjects and or science.
