Basics Of Crispr Cas Mediated Plant Genome Editing

CRISPR/Cas has emerged, as a powerful genetic engineering tool. It is simple yet highly affordable and robust. This book provides a basic introduction to the mechanism and architecture of the CRISPR/Cas. It enlightens the readers about the new advancements such as gene insertion, transcriptional activation, suppression, gene tagging, multiplexing, base editing, prime editing, and tissue culture free editing which makes it easier for crop improvement. With such technologies, application of genome editing has opened new paths for crop improvements and sustainable agriculture. The current book will be useful for beginners to understand these tools and how to use them in a better and more efficient way.

With over 820 million people facing hunger in today’s world, the need of the hour is the design of plant varieties with high yield, improved traits, and resistance properties in order to mitigate the detrimental impacts of biotic and abiotic stress conditions on food crops. This volume highlights the use of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) and CRISPR-associated nuclease proteins as a solution for sustainable agriculture. CRISPR/Cas-mediated genome editing (GE) provides a robust, simple, precise, efficient, economical, and revolutionary toolbox that leads to improved plant traits with enhanced yield, quality, and resistance against various stresses, including climate-related stress, insect pests and diseases, pollution-related stresses, etc. Key features of the book: Explains the differences between conventional breeding, genetically modified crops, and genome editing approaches using CRISPR/Cas Introduces the tools of genome editing, such as ZFNS (zinc finger nucleases), mega nucleases, and TLENS (transcription activator-like effector nucleases) Covers the history, origin, discovery, structure, and classification of CRISPR/Cas Examines the databases and computational approaches of CRISPR/Cas Highlights genome editing of important crop plants with CRISPR/Cas systems, including wheat, maize. tomato, Brassica crops, rice, fruits Explores potential applications of CRISPR/Cas systems for climate smart crops

This volume provides readers with wide-ranging coverage of CRISPR systems and their applications in various plant species. The chapters in this book discuss topics such as plant DNA repair and genome editing; analysis of CRISPR-induced mutations; multiplexed CRISPR/Cas9 systems; CRISPR-Cas12a (Cpf1) editing systems; and non-agrobacterium based CRISPR delivery systems. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Comprehensive and thorough, Plant Genome Editing with CRISPR Systems: Methods and Protocols is a valuable resource for any researcher interested in learning about and using CRISPR systems in plants.

Some of the advanced applications of CRISPR/Cas tools, such as base editing and RNA detection, along with regulatory aspects of genome-edited crops are described in detail. This book serves as a valuable resource to researchers in the field of crop improvement; graduate and postgraduate students engaged in plant molecular biology and biotechnology; academicians; and policy makers. Key Features: Addresses topics associated with historical development and principles of genome-editing technology Addresses basic mechanisms operating under each genome-editing technology Addresses its application in plants to design crops as per the current and future demands Addresses the regulatory mechanisms of genome-edited crops

This book offers a comprehensive collection of papers on CRISPR/Cas genome editing in connection with agriculture, climate-smart crops, food security, translational research applications, bioinformatics analysis, practical applications in cereals, floriculture crops, engineering plants for abiotic stress resistance, the intellectual landscape, regulatory framework, and policy decisions. Gathering contributions by internationally respected experts in the field of CRISPR/Cas genome editing, the book offers an essential guide for researchers, students, teachers and scientists in academia; policymakers; and public companies, private companies and cooperatives interested in understanding and/or applying CRISPR/Cas genome editing to develop new agricultural products.

Over the last few decades, various techniques have been developed to alter the properties of plants and animals. While the targeted transfer of recombinant DNA into crop plants remains a valuable tool to achieve a desirable breeding outcome, integration of transgenes into the host genome has been random, which in part, leads to reduced acceptance of GMOs by the general population in some parts of the world. Likewise, methods of induced mutagenesis, such as TILLING, have the disadvantage that many mutations are induced per plant, which has to be removed again by expensive backcrossing. Advances in genome sequencing have provided more and more information on differences between susceptible and resistant varieties, which can now be directly targeted and modified using CRISPR/Cas9 technology. By selecting specific gRNAs occurrence of off-target modifications are comparatively low. ZFNs and TALENs- based approaches required re-engineering a new set of assembled polypeptides for every new target site for each experiment. The difficulty in cloning and protein engineering prevented these tools from being broadly adopted by the scientific community. Compared to these technologies, designing the CRISPR toolbox is much simpler and more flexible. CRISPR/Cas9 is versatile, less expensive and highly efficient. It has become the most widely used technology for genome editing in many organisms. Since its inception as a powerful genome-editing tool in late 2012, this breakthrough technology has completely changed how science is performed. The first few chapters in this book introduce the basic concept, design and implementation of CRISPR/Cas9 for different plant systems. They are followed by in-depth discussions on the legal and bio-safety issues accompanying commercialization and patenting of this emerging technology. Lastly, this book covers emerging areas of new tools and potential applications. We believe readers, novice and expert alike, will benefit from this all-in-one resource on genome editing for crop improvement.
