Plants are vulnerable to pathogens including fungi, bacteria, and viruses, which cause critical problems and deficits. Crop protection by plant breeding delivers a promising solution with no obvious effect on human health or the local ecosystem. Crop improvement has been the most powerful approach for producing unique crop cultivars since domestication occurred, making possible the main innovations in feeding the globe and community development. Genome editing is one of the genetic devices that can be implemented, and disease resistance is frequently cited as the most encouraging application of CRISPR/Cas9 technology in agriculture. Nanobiotechnology has harnessed the power of genome editing to develop agricultural crops. Nanosized DNA or RNA nanotechnology approaches could contribute to raising the stability and performance of CRISPR guide RNAs. This book brings together the latest research in these areas. CRISPR and RNAi Systems: Nanobiotechnology Approaches to Plant Breeding and Protection presents a complete understanding of the RNAi and CRISPR/Cas9 techniques for controlling mycotoxins, fighting plant nematodes, and detecting plant pathogens. CRISPR/Cas genome editing enables efficient targeted modification in most crops, thus promising to accelerate crop improvement. CRISPR/Cas9 can be used for management of plant insects, and various plant pathogens. The book is an important reference source for both plant scientists and environmental scientists who want to understand how nano biotechnologically based approaches are being used to create more efficient plant protection and plant breeding systems. - Shows how nanotechnology is being used as the basis for new solutions for more efficient plant breeding and plant protection - Outlines the major techniques and applications of both CRISPR and RNAi technologies - Assesses the major challenges of escalating these technologies on a mass scale

This volume presents a comprehensive collection of cuttingedge methods for elucidating the function of new genes and altering gene expression. These readily reproducible techniques can be used either in transient and stable gene splicing applied to worms, flies, trypanosomes, mammals, and plants, or in studying RNA editing mechanisms in a wide range of organisms, including systems that involve the conversion of one base to another and insertion/deletion editing. Topics of interest include stable and transient RNA interference, gene silencing, RNA editing, bioinformatics, small noncoding RNAs, and RNomics. Special attention is given to methods for the identification and characterization of small RNAs involved in RNA interference or modification. Readily reproducible protocols for discovering new genes or altering gene expression.

RNAi technology is used for large-scale screens that systematically shut down each gene in the cell, which can help identify the components necessary for a particular cellular process or an event such as cell division. Exploitation of the pathway is also a promising tool in biotechnology and medicine. Introducing new technology in the study of RNA

This volume is a timely and comprehensive description of the many facets of DNA and RNA modification-editing processes and to some extent repair mechanisms. Each chapter offers fundamental principles as well as up to date information on recent advances in the field (up to end 2008). They ended by a shortconclusion and future prospect' section and

CRISPR/Cas is a recently described defense system that protects bacteria and archaea against invasion by mobile genetic elements such as viruses and plasmids. A wide spectrum of distinct CRISPR/Cas systems has been identified in at least half of the available prokaryotic genomes. On-going structural and functional analyses have resulted in a far greater insight into the functions and possible applications of these systems, although many secrets remain to be discovered. In this book, experts summarize the state of the art in this exciting field.

Naturally occurring RNA always contains numerous biochemically altered nucleotides. They are formed by enzymatic modification of the primary transcripts during the complex RNA maturation process designated RNA modification. A large number of enzymes catalyzing the formation of these modified nucleosides or converting one canonical base into another at the posttranscriptional level have been studied for many years, but only recently have systematic and comparative studies begun. The functions of individual enzymes and/or the modified/edited nucleosides in RNA, however, have remained largely ignored. This book provides advance information on RNA modification, including the associated editing machinery, while offering the reader some perspective on the significance of such modifications in fine-tuning the structure and functions of mature RNA molecules and hence the ability to influence the efficiency and accuracy of genetic expression. Outstanding scientists who are actively working on RNA modification/editing processes have provided up-to-date information on these intriguing cellular processes that have been generated over the course of millions of years in all living organisms. Each review has been written and illustrated for a large audience of readers, not only specialists in the field, but also for advanced students or researchers who want to learn more about recent progress in RNA modification and editing.
