Download or read book Virus Resistant Transgenic Plants Potential Ecological Impact written by Mark Tepfer and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of novel genes into plants by genetic transformation holds great promise for plant breeding, and many crop species have been rendered virus-resistant by expression of viral sequences. However, it is essential to also evaluate the potential risks associated with this new technology. Among the types of genetically modified plants that could represent potential ecological risks, ones expressing viral sequences pose questions of particular interest. In this volume special attention is given to recombination in plants expressing sequences of RNA or DNA viruses, heterologous encapsidation or other forms of complementation in plants expressing coat protein genes, potential deleterious effects of satellite RNAs associated with cucumber mosaic virus, and sexual transmission of virus resistance genes to potentially weedy relatives.

Download or read book Genes Genetics and Transgenics for Virus Resistance in Plants written by Patil L. Basavaprabhu and published by . This book was released on 2018-09 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viral diseases of crop plants cause significant yield and economic losses and this poses a major threat to global food security. To make matters worse there are no effective antiviral chemicals available and, although naturally resistant host genotypes exist, they are so rare that conventional breeding techniques cannot be used reliably to create resistant plants. The most effective option to combat phytopathogenic viruses is through biotechnological intervention, such as the use of genetic engineering to develop transgenic plants or the topical use of RNA silencing technologies to prevent or modulate the severity of the viral infection. Since the first report on the virus resistance of transgenic tobacco plants in 1986, enormous progress has been made in this field. In addition great strides have been made in our ability to genetically manipulate plants and viruses leading to a plethora of novel applications. This has prompted the need for this timely book which distills the most important research to provide a timely overview. This authoritative book contains fifteen chapters whose breadth reflects the diversity of this research area. Topics covered range from: understanding the mechanisms of virus resistance in plants, and the management of whitefly-transmitted viruses, to the principles and methods involved in genetic engineering of virus resistant plants. Other chapters cover individual crops such as papaya, cassava, rice, tomato, and banana, for which virus resistance has been accomplished by employing different transgenic technologies. This volume is essential reading for everyone working in this field, both students and specialists, from academia, research institutes/organizations and industries.

Available in PDF, EPUB and Kindle. Book excerpt: Concern about the environmental consequences of the widespread use of pesticides has increased, and evidence of pesticide-resistant virus vectors have continued to emerge. This volume presents a timely survey of the mechanisms of plant resistance and examines current developments in breeding for resistance, with particular emphasis on advances in genetic engineering which allow for the incorporation of viral genetic material into plants. Discusses the mechanisms of innate resistance in strains of tobacco, tomato, and cowpea; various aspects of induced resistance, including the characterization and roles of the pathogenesis-related proteins; antiviral substances and their comparison with interferon; and cross-protection between plant virus strains. Also presents several papers which evaluate the status of genetic engineering as it relates to breeding resistant plants. Among these are discussions of the potential use of plant viruses as gene vectors, gene coding for viral coat protein, satellite RNA, and antisense RNA, and practical issues such as the durability of resistant crop plants in the field.

Download or read book Transgenic Plants written by Leandro Peña and published by Springer Science & Business Media. This book was released on 2008-02-05 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of Transgenic Plants: Methods and Protocols is to provide a source of information to guide the reader through a wide range of frequently used, broadly applicable, and easily reproducible techniques involved in the gene- tion of transgenic plants. Its step-by-step approach covers a series of methods for genetically transforming plant cells and tissues, and for recovering whole transgenic plants from them. The volume then moves on to the use of sele- able and reporter markers, positive selection, marker elimination after rec- ery of transgenic plants, and the analysis of transgene integration, expression, and localization in the plant genome. Although contributors usually refer to model plants in most chapters, the protocols described herein should be widely applicable to many plant species. The last two sections are devoted to me- ods of risk assessment and to exploring the current and future applications of transgenic technology in agriculture and its social implications in a case study. Transgenic Plants: Methods and Protocols is divided into six major s- tions plus an introduction, comprising 27 chapters. Part I, the Introduction, is a review of the past, present, and perspectives of the transgenic plants, from the discovery of Agrobacterium tumefaciens as a feasible transformation vector, to its use as a tool to study gene expression and function, and the current and possible future applications of this technology in agriculture, industry, and medicine.

Download or read book Plant Virology Protocols written by Gary D. Foster and published by Springer Science & Business Media. This book was released on 2008-02-03 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of Plant Virology Protocols is to provide a source of infor- tion to guide the reader through the wide range of methods involved in gen- ating transgenic plants that are resistant to plant viruses. To this end, we have commissioned a wide-ranging list of chapters that will cover the methods required for: plant virus isolation; RNA extraction; cloning coat p- tein genes; introduction of the coat protein gene into the plant genome; and testing transgenic plants for resistance. The book then moves on to treatments of the mechanisms of resistance, the problems encountered with field testing, and key ethical issues surrounding transgenic technology. Although Plant Virology Protocols deals with the cloning and expression of the coat protein gene, the techniques described can be equally applied to other viral genes and nucleotide sequences, many of which have also been shown to afford protection when introduced into plants. The coat protein has, however, been the most widely applied, and as such has been selected to illustrate the techniques involved. Plant Virology Protocols has been divided into six major sections, c- taining 55 chapters in total.

Download or read book Advances in Plant Transgenics Methods and Applications written by Ramalingam Sathishkumar and published by Springer Nature. This book was released on 2019-11-15 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: The green revolution led to the development of improved varieties of crops, especially cereals, and since then, classical or molecular breeding has resulted in the creation of economically valuable species. Thanks to recent developments in genetic engineering, it has become possible to introduce genes from different sources, such as bacteria, fungi, viruses, mice and humans, to plants. This technology has made the scientific community aware of the critical role of transgenics, not only as a means of producing stress tolerant crops but also as a platform for the production of therapeutics through molecular farming. This book discusses the commercial applications of plant transgenic technologies, including the use of transgenic cell culture approachesto improve the production of metabolites and high-value therapeutics as well as transgenic plants in pest management. It also explores generation of novel vectors, protein production using chloroplast engineering and the latest developments in this area, such as genome editing in plants. Featuring general discussions and research papers by leading international experts, it is a valuable resource for scientists, teachers, students and industrialists working in the field.

Download or read book Genetically Engineered Crops written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-01-28 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.
