Microbial Plant Pathogens-Detection and Disease Diagnosis: by P. Narayanasamy Pdf

Morphological, biological, biochemical and physiological characteristics have been used for the detection, identification and differentiation of fungal pathogens up to species level. Tests based on biological characteristics are less consistent. Immunoassays have been shown to be effective in detecting fungal pathogens present in plants and environmental samples. Development of monoclonal antibody technology has greatly enhanced the sensitivity and specificity of detection, identification and differentiation of fungal species and varieties/strains. Nucleic acid-based techniques involving hybridization with or amplification of unique DNA have provided results rapidly and reliably. Presentation of a large number of protocols is a unique feature of this volume.

Sustainable Approaches to Controlling Plant Pathogenic Bacteria by V. Rajesh Kannan,Kubilay Kurtulus Bastas Pdf

Plant diseases and changes in existing pathogens remain a constant threat to our forests, food, and fiber crops as well as landscape plants. However, many economically important pathosystems are largely unexplored and biologically relevant life stages of familiar systems remain poorly understood. In a multifaceted approach to plant pathogenic behavioral control, Sustainable Approaches to Controlling Plant Pathogenic Bacteria discusses the impact of plant pathogenic bacterial pathogenesis on scientific and economic levels. It introduces mechanisms, measuring tools, and controlling strategies you can use to meet the challenge of developing new and innovative ways to control plant diseases. The book covers many aspects of the activities of pathogenic bacteria that interact with plants. With chapters contributed by experts, the book focuses on: Pathogenesis Epidemiology Forecasting systems Control measures including diagnosis, quarantine, and eradication Adoption of agro-traditional practices Tools for the control of antibacterial polypeptides Nutrient supplements Metabolic substances from other organisms Mechanisms of siderophores Host resistances Quorum sensing and quenching Seed and foliar applications Impact of plant pathogens on scientific and economic levels The editors’ approach provides a broad perspective, including modern trends in ecology that consider plant pathogenic bacterial control from all angles. The discussions and reviews in the book cover a wide range of aspects of plant pathogenic bacterial pathogenicity, epidemiology, and impact on the food chain as well as strategies for control, which will help you develop sustainable methods for controlling plant diseases.

Plant Pathology and Plant Pathogens by John A. Lucas Pdf

An updated guide to plant pathogens and their management The impact of plant disease is far-reaching. Its effects are felt not only in the spheres of agriculture and horticulture, but also in human health and wellbeing. The challenges of population growth, climate change and global food security all increase the need to protect crops from disease and reduce the losses caused by plant pathogens. This requires ongoing research and novel solutions, making the detailed analysis offered by Plant Pathology and Plant Pathogens more relevant than ever. Striking a balance between laboratory- and field-based aspects of its subject, this revised fourth edition of the text places plant disease in a wide biological context. Its contents cover causal agents and diagnosis, host–pathogen interactions, and disease management, including breeding for resistance, chemical, biological and integrated control. New to this edition are updated sections on molecular epidemiology, biosecurity, pathogenomics, and the biotechnological advances that are helping scientists make great strides in the fight against plant disease. Authored by a leading authority on plant pathology Offers new coverage of recent advances in molecular genetics and genomics, biotechnology, and plant breeding Places emphasis on interaction biology and biological concepts, such as immunity and comparisons with animal systems Includes access to a supplementary website featuring slides of all figures in the book Plant Pathology and Plant Pathogens is an ideal textbook for graduate and upper-level undergraduate students in biology, botany, agricultural sciences, applied microbiology, plant-microbe interactions, and related subjects.

Microbial Plant Pathogens by Perumal Narayanasamy Pdf

Healthy seeds and propagules are the basic requirement for producing good grains, fruits and vegetables needed for human survival and perpetuation. Dispersal of microbial plant pathogens via seeds and propagules has assumed more importance than other modes of dispersal, as infected seeds and propagules have the potential to become the primary sources of carrying pathogen inoculum for subsequent crops. Several diseases transmitted through seeds and propagules have been shown to have the potential to damage economies as a result of huge quantitative and qualitative losses in numerous crops. Hence, it is essential to rapidly detect, identify and differentiate the microbial plant pathogens present in seeds and propagules precisely and reliably, using sensitive techniques. Microbial Plant Pathogens: Detection and Management in Seeds and Propagules provides a comprehensive resource on seed-borne and propagule-borne pathogens. Information on the biology of microbial pathogens, including genetic diversity, infection process and survival mechanisms of pathogens and epidemiology of diseases caused by them, are discussed critically and in detail to highlight weak links in the life cycles of the pathogens. Development of effective disease management systems, based on the principles of exclusion and eradication of pathogens and immunization of crop plants to enhance the levels of resistance of cultivars to diseases, has been effective to keep the pathogens at bay. The need for production of disease-free seeds/propagules has been emphasized to prevent the carryover of the inoculum to the next crop or introduction of the pathogens to other locations. Effectiveness of adopting simple cultural practices and development of cultivars resistant to diseases through traditional breeding methods or biotechnological approach have resulted in reducing the pathogen inoculum and disease incidence. Although application of different chemicals may reduce the disease incidence effectively, biological management of crop diseases, employing potential biological control agents have to be preferred to preserve the agroecosystems. Greater efforts have to be made to integrate compatible strategies to enhance the effectiveness of diseases management systems. Protocols appended at the end of relevant chapters form a unique feature of this book to enable the researchers to fine-tune their projects. This 2 volume set provides comprehensive and updated information about the economically-important groups of microbial plant pathogens carried by seed and propagules. Graduate students, researchers and teachers of plant pathology, plant protection, microbiology, plant breeding and genetics, agriculture and horticulture, as well as certification and quarantine personnel will find the information presented in this book useful.

Pathogen and Microbial Contamination Management in Micropropagation by Alan C. Cassells Pdf

This book is based mainly on invited and offered papers presented at the Second International Symposium on Bacterial and Bacteria-like Contaminants of Plant Tissue Cultures held at University College, Cork, Ireland in September 1996, with additional invited papers. The First International Symposium on Bacterial and Bacteria-like Contaminants of Plant Tissue Cultures was held at the same venue in 1987 and was published as Acta Horticulturae volume 225, 1988. In the intervening years there have been considerable advances in both plant disease diagnostics and in the development of structured approaches to the management of disease and microbial contamination in micropropagation. These approaches have centred on attempts to separate, spatially, the problems of disease transmission and laboratory contamination. Disease-control is best achieved by establishing pathogen-free cultures while laboratory contamination is based on subsequent good working practice. Control of losses due to pathogens and microbial contamination in vitro addresses, arguably, the most importance causes of losses in the industry; nevertheless, losses at and post establishment can also be considerable due to poor quality microplants or micro-shoots. In this symposium, a holistic approach to pathogen and microbial contamination control is evident with the recognition that micropropagators must address pathogen and microbial contamination in vitro, and diseases and microplant failure at establishment. There is increasing interest in establishing beneficial bacterial and mycorrhizal association with microplants in vitro and in vivo.

Molecular Biology in Plant Pathogenesis and Disease Management by P. Narayanasamy Pdf

Studies on molecular biology of pathogens, infection process and disease resistance, have provided information essentially required to understand the vulnerable stages at which the pathogens can be tackled effectively and to adopt novel strategies to incorporate disease resistance genes from diverse sources and /or to induce resistance of cultivars with desirable agronomic attributes using biotic or abiotic agents. The nature of interaction between the gene products of the pathogen and plant appears to determine the outcome of the interaction resulting in either disease progression or suppression. Transgenic plants with engineered genes show promise for effective exploitation of this approach for practical application. Research efforts during the recent years to sequence the whole genomes of the pathogens and plants may lead to development of better ways of manipulating disease resistance mechanisms enabling the grower to achieve higher production levels and the consumer to enjoy safer food and agricultural products. Experimental protocols included in appropriate chapters will be useful for researchers and graduate students.
