Download or read book Mechanisms of Resistance to Plant Diseases written by R.S. Fraser and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant resistance to pathogens is one of the most important strategies of disease control. Knowledge of resistance mechanisms, and of how to exploit them, has made a significant contribution to agricultural productivity. However, the continuous evolution of new variants of pathogen, ana additional control problems posed by new crops and agricultural methods, creates a need for a corresponding increase in our understanding of resistance and ability to utilize it. The study of resistance mechanisms also has attractions from a purely academic point of view. First there is the breadth of the problem, which can be approached at the genetical, molecular, cellular, whole plant or population lev~ls. Often there is the possibility of productive exchange of ideas between different disciplines. Then there is the fact that despite recent advances, many of the mechanisms involved have still to be fully elucidated. Finally, and compared with workers in other areas of biology, the student of resistance is twice blessed in having as his subject the interaction of two or more organisms, with the intriguing problems of recognition, specificity and co-evolution which this raises.

Download or read book Fungicide Resistance in Plant Pathogens written by Hideo Ishii and published by Springer. This book was released on 2015-08-31 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers a comprehensive coverage of the general principles and recent advances in fungicide resistance. It describes the development, mechanisms, monitoring, and management of resistance and covers the most important group of fungicides that have caused resistance on various crops. An historical review of fungicide resistance over the past 40 years sets the scene for up-to-date basic information on mode of action, as well as the genetics, mechanisms, and evolution of resistance. Monitoring for resistance, including the latest developments in molecular diagnostics, moves readers into the practical aspects of resistance management, which is dealt with through a series of case studies outlining fungicide-use strategies on several key crops. The chapters reflect the experience of authors internationally recognised for their significant contributions to fungicide resistance research. The majority of crop diseases are caused by fungal pathogens, and disease control relies heavily on chemically synthesized fungicides. However, modern fungicides often encounter the problem of resistance development in target pathogens. Thus pathogen resistance to fungicides is an important factor that causes loss of yield and quality of crops. It often threatens biosecurity through the decrease of fungicide efficacy in the fields. To manage fungicide resistance successfully will require the promotion of integrated disease management, involving not just chemical fungicides, but also host plant resistance, agronomic factors, and reliable biological control agents where these are available. Well referenced throughout, the book offers a comprehensive account of resistance, which will be useful as a source of material for lecturers and for both industrial and academic scientists involved in fungicide resistance research. It is also a valuable sourcebook for students.

This book was released on 2013-11-11 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: This treatise is focused on early aspects of fungal pathogenesis in plant and animal hosts. Our aim in choosing the topics and contributors was to demonstrate common approaches to studies of fungal-plant and fungal-animal interactions, particularly at the biochemical and molecular Ievels. For example, the initial events of adh«sion of fungal spores to the exposed surface tissues of the host are essential for subsequent invasion of the plant or animal and establishment of pathogenesis. A point of consensus among investigators who have directed their attention to such events in plants, insects, and vertebrates isthat spore adhesion to the host cuticle or epithelium is more than a simple binding event. lt is a complex and potentially pivotal process in fungal-plant interactions which "may involve the secretion of ftuids that prepare the infection court for the development of morphological stages of the germling" and subsequent invasion of the host (Nicholson and Epstein, Chapter 1). The attachment of the fungal propagule to the arthropod cuticle is also "mediated by the chemical components present on the outer layer of the spore wall and the epicuticle . . . . Initial attachment may be reinforced further by either the active secretion of adhesive materials or the modification of spore wall materiallocated at the [fungal spore arthropod] cuticle interface (Boucias and Pendland, Chapter 5).

Download or read book Omics and System Biology Approaches for Delivering Better Cereals written by Dinesh Kumar Saini and published by CRC Press. This book was released on 2024-11-08 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cereals like wheat, rice, maize, and barley have long been the dominant crops in agriculture, providing a significant portion of our food supply. Plant breeders and geneticists have always been interested in improving the yield and quality of cereals. The primary challenges in cereal breeding lie in adapting to climate change and enhancing yield and stress tolerance. In recent years, omics approaches such as genomics, transcriptomics, proteomics, and metabolomics have emerged as valuable tools to understand the genetic and molecular basis of cereal development under optimum and stress conditions. However, studying individual datasets for different cereals has limited our comprehensive understanding of complex traits and biological networks. To overcome this limitation, a systems biology approach is necessary. Systems biology integrates multiple omics data, modeling, and cell activity prediction to gain a holistic understanding of biological processes. By considering the whole system and its interactions, rather than isolated components, researchers can develop predictive models and even re-engineer cells. In the context of cereal improvement, systems biology can play a crucial role in identifying and introducing desirable traits such as yield, quality, and stress tolerance. It may help researchers uncover the molecular underpinnings of complex traits and offer insights for enhancing cereals on a national and international scale. The book explores available omics resources, the integration of multi-omics data, and systems biology methods, focusing on their applications in cereals breeding and research. It highlights current and innovative strategies to understand complex traits, improve yield, and enhance resistance to biotic and abiotic stresses. It also addresses the challenges and opportunities associated with modeling multi-omics data and analyzing systems-level information. By leveraging systems biology and integrated omics research, this book aims to redefine the future research agenda for cereal improvement.
