Available in PDF, EPUB and Kindle. Book excerpt: "The Fusarium wilt disease of tomato caused by Fusarium oxysporum f. lycopersici (Sacc.) Snyder and Hansen (F. lycopersici) was first noted in the Channel Islands a few years before 1895 (Walker, 1950). Today, the disease is as widespread as its host, Lycopersicon esculentum Mill. Economic losses due to this disease throughout the world amount to several millions of dollars every year. Numerous scientists have undertaken studies on this disease either because of its economic importance or as a subject for investigations on host-parasite relationships. [...]" --

Available in PDF, EPUB and Kindle. Book excerpt: The host and the parasite are the two different biological organisms involved in host parasite interactions. The parasite or pathogen is a benefited organism which is dependent on the host for its existence. The host and the parasite live in close proximity and the latter enjoys at the expense of the first. The parasite is like an intruder for the host which it wants to eliminate by various responsive reactions and resistance. In response, parasite generates several features such as polyembryony, production of special enzymes, increased fecundity, self-habitat, etc. This close association is referred to as host parasite interactions. Different types of parasites have been recognized on different basis. In terms of host specificity, parasites may be mono-specific or poly-specific. Mono-specific parasite restricts to a single host whereas poly-specific might associate with different genetically related hosts. Eventually, a mutual relation between the host and the parasite develops which allows them to survive together. The fatal parasites, however, try to kill the hosts. But killing the hosts will lead to the death of parasites itself. Host characteristics might be affected by intimate association with the parasite. These may include damage of tissue, necrosis, hyperplasia, neoplasia, malnourishment, etc. There are several parasitic plants and fungi which attack the plants. Parasitic plant extracts its resources from the vascular system of another living plant (host) using a specialized transfer organ called haustorium. Some examples of parasitic plants include Mistletoes, Yellow Rattle (Rhinanthus), Red Bartsia (Odontites) and Eyebrights (Euphrasia). These are hemi-parasitic members and have their own green leaves. Plants like Toothworts (Lathraea) and Broomrapes (Orobanche) are the examples of holo-parasitic plants which have no photosynthetic green leaves of their own. The Dodders (Cuscuta) are another common group of parasites. This book discusses the plant host parasite relationship and is a gathering of few research papers on interactions of parasitic plants/fungi with the host plants. The first three chapters throw light on the overview of host parasite interactions in plants. Chapter 4 describes the genetic transfer facilitation among plants by the association between the host and the parasite. The next chapter focuses on the interaction of Cuscuta reflexa with tomato plant. The molecular events during the parasitic plant host interaction are described in chapter 6. The next chapter covers the applicability of Limiting Resource Model (LRM) for understanding the effects of drought on tolerance to holoparasite Cuscuta gronovii. Chapter 8 discusses the compatibility or incompatibility of hosts by screening the response of four plant species of Solanaceae family to the parasitism of Cuscuta campestris Yuncker. Horizontal gene transfer between the host and the parasite nuclear genomes; and the consequences of Orobanche crenata infection severity in different legume crops viz. faba bean, field pea and grass pea have been discussed in chapters 9 and 10, respectively. Chapter 11 evaluates the effect of amino acids as herbicides for field control of Orobanche minor parasitism in red clover. The relationships of the parasitic plant Phelipanche ramosa (L.) and different hosts; and the microbiome of the parasitic weed Phelipanche aegyptiaca and tomato is described in the following two chapters, respectively. The last chapter discusses how water influences the effects of stem hemiparasites on hosts.

This book was released on 2012-09-14 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the recent years, the need to increase food production to meet the demands of rapidly increasing population from a limited land resource necessitated the use of intensive farming systems, with the inputs like narrow genetic base, high dose of fertilizers, pesticides, irrigation, monocropping, etc. which led to the development of diseases and pest. The effect of changing global climate, particularly the sharp increase in CO2 concentration, has increased the susceptibility of plants to pathogens and pests. Because of the chemicalization of agriculture, the age-old eco-friendly pest management practices like sanitation, crop rotation, mixed cropping, adjustment of date of planting, fallowing, summer ploughing, green manuring, composting, etc. are not being practiced, affecting the crops adversely. This has encouraged researchers to look for eco-friendly and novel approaches for pest management. The information on recent advances in crop protection (involving bacteria, fungi, nematodes, insects, mites and weeds) is scattered. The book delves upon the most latest developments in crop protection such as avermectins, bacteriophages, biofumigation, biotechnological approaches; bio-priming of seeds; disguising the leaf surface; use of non-pathogenic strains, plant defense activators, plant growth promoting rhizobacteria, pathogenesis-related proteins, strobilurin fungicides, RNA interference, and variety of mixtures/cultivar mixtures/multilines; soil solarization; biointensive integrated pest management; among several others (fusion protein-based biopesticides, seed mat technology and environmental methods). This book is a ready reference for students, policy-makers, scientists, researchers and extension workers.

Book excerpt: Specialists from a number of different disciplines have contributed to this book which presents actual basic and applied findings on Fusarium species, on their metabolites and taxonomy, in connection with pathogenicity to cereal plants and potato tubers. Over 100 metabolites produced by Fusaria are described together with results of studies on their occurrence in agricultural products, their metabolism in farm animals, and possibilities of elmination and detoxification during technological processes. Pathogenic Fusarium species are described from the point of view of their taxonomy, profiles of produced metabolites, ecology, pathogenicity and interaction with cereal tissues. Finally, some actual solutions to avoid cereal grain contamination are discussed, mainly in connection with agricultural practices and breeding programmes.The interdisciplinary and comprehensive nature of the book makes it particularly useful to all who are studying or teaching plant pathology, plant breeding, animal nutrition and any other area in which Fusaria and their metabolites play an important role.

Available in PDF, EPUB and Kindle. Book excerpt: Nematode interactions are important biological phenomena and of great significance in agriculture. It is a fascinating subject which is multidisciplinary by nature, and concerns any scientist involved with plant health. There have been marked advances in our knowledge of various aspects of the subject in the last two decades. This study area has been the subject of several reviews, but there was no exclusive text on the subject. This has stressed the need to document the information, developing a unifying theme which treated nematode interactions in a holistic manner. This book is about the inter action of plant-parasitic nematodes with other plant pathogens or root symbionts, the nature of their associations, their impact on the host and con sequential interactive effects on the involved organisms. Since nematodes are at the centre of the theme, the responsibility of understanding of other plant pathogens dealt with in this book is largely delegated to the reader. I have limited the book content to interactions with biotic pathogens and root symbionts only, for various reasons. The book embodies 16 chapters, and attempts to present balanced infor mation on various aspects of nematode interactions with other plant pathogens and root symbionts. Some chapters describe general aspects of the subject. Interactions of nematodes with specific groups of organisms are addressed in the remaining chapters.

Available in PDF, EPUB and Kindle. Book excerpt: Fungal Wilt Diseases of Plants focuses on wilt diseases caused by the fungal genera Verticillium, Fusarium, and Ceratocystis. Special attention is given to the interactions of physiological, biochemical, and anatomical factors, as these relate to pathogenesis and mechanisms of disease resistance. Organized into 16 chapters, this book begins with a description, in a historical perspective, of the major research themes in fungal wilt diseases. It then looks into the worldwide status of this plant disease. The three subsequent chapters describe the epidemiology and life cycle of the major fungal wilt pathogens in Fusarium, Verticillium, and Ceratocystis. This book also provides an in-depth view of the genetics and biochemistry of these pathogens; the nature of pathogenesis and the effects of wilt pathogens on host-water relations; and the sources and genetics of host resistance in field and fruit crops, vegetable crops, and shade trees. Other chapters are dedicated to the biochemistry, physiology, and the anatomical aspects of resistance and to the progress in the biological and chemical control of these pathogens. This text will be of great value to graduate students and senior research scientists in plant pathology, physiology, and biochemistry, who are specifically involved in studying wilt diseases and host-parasite interactions. It will provide them the detailed background information needed to supplement their specialized research interests.

Download or read book Plant Pathology V1 written by James G. Horsfall and published by Elsevier. This book was released on 2012-12-02 with total page 689 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Pathology: An Advanced Treatise, Volume I: The Diseased Plant presents an integrated synthesis of the scope, importance, and history of plant pathology, emphasizing the concept of disease, not of diseases. The book focuses on pathological processes, defense devices, predisposition, and therapy of the diseased plant. It explores the normal pathways that are obstructed in sick plants; how the pathogen causes dysfunction; and how the host plant reacts to the pathogen. This book also considers the logistics and the strategy of disease and how to combat it. This volume is organized into 15 chapters and begins with an overview of plant pathology, its history, and its relation to other sciences, along with plant predisposition to disease, and the resistance-susceptibility problem. The next chapters examine how sickness in plants is recognized and diagnosed, the tissue breakdown in diseases, and the effects of parasites on the processes in plants. The impact of disease on water balance and respiration in plants and the histology of disease resistance in plants are also explained. This volume also covers the physiological and chemical basis of defense by higher plants against potential or invading pathogens and the hypersensitivity concept in plant pathology. The final chapter discusses the physical and chemical therapy of the diseased plant. This book will appeal to all who are interested in a theoretical treatment of plant pathology and in the broad ecological relationships among organisms, as well as to research workers and advanced students of applied biology.
