Applications Of Novel Gene Editing Tools And Approaches In Plants

Genome Editing in Plants: Principles and Applications addresses the information of genome editing starting from principles and historical aspects to the latest advancements in the field. As genome-editing technology has emerged as promising and cutting edge, researchers around the world have started producing original research outputs, which have significantly improved our current understanding and potential of this technology. The initial chapters of this book describe different genome-editing tools as well as their principles and applications. Other chapters are dedicated to the present status and future applications of genome-editing techniques in various crop improvement programmes. 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

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.

Genome-editing methods are becoming routine tools for molecular and cell biologists. Such tools include ZFNs, CRISPR, megaTALs and TALENs. These tools are revolutionizing the creation of precisely manipulated genomes to modify the characteristics of organisms or cells. Additionally, gene drives have altered the way we understand inheritance laws. They give us the ability to have total control of the inheritance of traits of choice and importance. This succinct volume summarizes the history, principles and applications – as well as the advantages and disadvantages – of each of these tools and various kinds of gene drives. The book is part of a program to produce books helpful to students and faculties of science at colleges and universities. This volume in the Pocket Guides to Biomedical Sciences series will help demystify these technologies. The book fills the gap between established conventional methods and the novel and exciting newly introduced tools of genome editing and gene drives. It will help young scientists understand the emerging genome-editing tools and gene drives, thereby promoting related research and adoption.

This book is a collection of information about applying CRISPR-Cas systems for genome editing in plants. The main focus of this book is to address the recent advances and future prospects of CRISPR-Cas technology in crops. Genome editing technology is important because it can be used to improve plant traits. The earlier genome-engineering tools, zinc finger nucleases (ZFNs), and TAL effector nucleases (TALENs) are complicated to design and not flexible. The novel genome editor, CRISPR-Cas systems, has advantages over ZFNs and TALENs. The advantages are simple and easy to design precision in targeting and efficiency. Due to its precision and simplicity, the CRISPR-Cas technology has rapidly become the most popular genome-editing platform in life-science fields. CRISPR-Cas technology has been used widely for human gene therapy to treat diseases and for plant breeding programs for crop improvement. This book is of interest and useful to genome-editing professionals, plant breeders, horticulturists, field-level extension workers, nurserymen, planters, ecologists, and valuable source of reference to the relevant researchers.

Gene or genome editing is barely two decades old, but its impact is palpable in every discipline of biological sciences, especially basic and applied biomedical researches. It enables a planned and precise alterations in genome sequences as well as controlled activation or repression of selected gene functions. Base editors based on CRISPR-Cas system were created a couple of years ago, and they permit permanent conversion of the single targeted base pair into another base pair. The potential of this powerful discipline are testified by its contributions in the form of gene therapies of otherwise intractable human diseases and improved crop varieties with novel traits. The present book is designed to provide the basic principles of gene editing as well describe its realized and potential applications. The book targets biologists in general and geneticists, biomedical researchers and plant breeders in particular. It is hoped that it will be useful to post-graduate students, research scholars and research workers concerned with analyses of biological phenomena and development of strains with novel and useful traits.
