Download or read book The Nature of Fusarium Wilt Disease Resistance in Tomato written by Erik Leslie Stromberg and published by . This book was released on 1977 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioassays of acetone extracts from xylem tissue in tomato stems and corresponding reductions in Fusarium oxysporum f.sp. lycopersici race 1 or 2 populations within the stems suggest that fungitoxic materials within the xylem vessels of Bonny Best, Jefferson, and Marglobe tomato cultivars initially kill a portion of the inoculum conidia. In the susceptible host-pathogen combinations, the pathogen eventually grows extensively in the xylem vessels and severe disease symptoms follow closely the proliferation of the pathogen. Acetone extracts from the susceptible Bonny Best cultivar do not become highly fungitoxic until eight or nine days after inoculation when the disease symptoms are already severe. Xylem extracts from the multigenic resistant Marglobe, however, do not become fungitoxic, even 11 days after inoculation with race 1 of the pathogen when the disease symptoms are severe and the Fusarium population is seven times that in Bonny Best-race 1 inoculated plants. In the monogenic resistant Jefferson-race 1 combination, within three to four days after inoculation the xylem extracts become highly fungitoxic, the fungal population within the stem remains low and disease symptoms fail to develop. The xylem extracts from race 1 resistant Jefferson inoculated with race 2 of the pathogen do not become fungitoxic even when disease symptoms are exhibited and the Fusarium population has reached a peak nearly three times that in Bonny Best-race 1 inoculated plants. Conidia of race 2 were as sensitive to the xylem toxicants produced in response to infection by race 1 as were race 1 conidia. The breaking of Fusarium wilt resistance by race 2 of the pathogen may be a result of this race's failure to induce the production or release of fungitoxic materials in the xylem of Jefferson in response to infection and is not due to resistance of race 2 to toxicants in Jefferson. Xylem vessels in stems of Jefferson (race 1 resistant and race 2 susceptible) and Bonny Best (race 1 susceptible) tomato cultivars inoculated with Fusarium oxysporum f.sp. lycopersici race 1 or 2 were examined by scanning electron microscopy. Four days after inoculation of Jefferson with race 1 conidia, the inoculum conidia and resultant hyphae were collapsed, while in the susceptible host-pathogen combinations the conidia and hyphae appeared normal. Vessel elements of both resistant and susceptible host-pathogen combinations had no perforation plates or tyloses capable of trapping conidia or effectively blocking hyphal growth within the vessel elements. Perforation plates are reduced to slightly lipped rims at the ends of vessel elements thereby providing an unrestricted aperature for hyphal growth and conidial movement in the transpiration stream. In the susceptible host-pathogen combinations, mycelial growth often filled vessel lumens, but no sporulation was noted. Frequent lateral spread of the pathogen occurred from one vessel element to adjacent vessel elements through common pits. The infrequent occurrence of tyloses (in less than 1% of vessel elements) and lack of complete occlusion by tyloses in the resistant host-pathogen combination suggest that vascular wilt resistance is not due to physical containment of the pathogen. Collapsed conidia and hyphae in the resistant Jefferson-race 1 combination may indicate that fungitoxic materials suppress the pathogen and lead to resistance.

Download or read book Fusarium written by Tulin Askun and published by BoD – Books on Demand. This book was released on 2018-07-25 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusarium species are ubiquitous environmental fungi and can cause severe invasive infections in plants. They are crop pathogens, and consumption of such infected crops can cause diseases in humans and animals. Furthermore, they act as spoilage organisms in stored products, such as wheat, sorghum, rice, and corn (maize). Fusarium species are mycotoxin producers and contaminate food and grains. Therefore, their eradication and management have economic importance as they can cause enormous economic and agricultural production losses. Despite the fact that the genus Fusarium Link (1809) has been known for over 200 years, new scientific information is being revealed by rapid advancements and breakthrough findings of interdisciplinary studies. This book presents an introductory overview of an update to the scientific knowledge about Fusarium. It discusses various aspects of Fusarium, such as its genetic diversity, root rot incidence and severity, genetic resistance, molecular markers, mycotoxins, diseases caused by Fusarium, and their management and the biological control of these phytopathogens. Furthermore, it also elaborates upon new plant secondary metabolites that are effective against Fusarium and the molecular interaction between Fusarium and the plant.

Download or read book A Molecular Vision of the Interaction of Tomato Plants and Fusarium Oxysporum F Sp Lycopersic written by Ema Laura García-Enciso and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusarium oxysporum causes vascular wilt disease in a broad range of crops, including tomato (Solanum lycopersicum). Tomato, a major and important vegetable crop, is susceptible to F. oxysporum f. sp. lycopersici (FOL), a biotrophic pathogen that is the causal agent of tomato wilt resulting in significant yield losses each year. Development of disease in susceptible tomato plants requires FOL to advance through a series of transitions, beginning with spore germination and culminating with establishment of a systemic infection. In addition, many host attributes, including the composition of root exudates, the structure of the root cortex, and the capacity to recognize and respond quickly to invasive growth of a pathogen, can impede the development of FOL. FOL divides into races on the basis of the ability of individual strains to overcome specific genes. This implies the presence of avirulence genes (Avr) in the fungus that is recognized by products of the corresponding genes. In tomato, resistance (R) genes against the wilt-inducing FOL are called immunity genes, and the interaction between these genes will determine the success of the infection.

Download or read book Host Pathogen Interactions in Plant Disease written by J. E. Vanderplank and published by Elsevier. This book was released on 2012-12-02 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the genetics, biochemistry, and epidemiology of host-pathogen interactions in plant disease, especially as they concern the breeding of crops for disease resistance. It analyzes a wealth of information that has not previously been recorded in other books or reviews. Some of it stems from basic surveys of disease in the field. The analysis of these surveys not only explains a great deal about host-pathogen interactions that was heretofore obscure, but also indicates directions for future research. Other data, from original papers, have now been coordinated for the first time and organized in a way that suggests new areas of research. The book contains more than fifty new tables that integrate data and relate them to general principles of host-pathogen interactions.For plant pathologists and plant breeders concerned with the control of plant disease, the book shows how to manipulate the host and, indirectly, the pathogen in order to control disease. It analyzes records of resistance against disease that time has shown to be stable in an effort to determine what has kept this resistance stable. It also analyzes the structure of virulence in populations of a pathogen, and demonstrates how virulence can be deliberately restricted. The author updates information on the gene-for-gene hypothesis and discusses the numerical and biological implications of the hypothesis. He analyzes the structure of epidemics based on three fundamental variables: the initial inoculum, the progeny/parent ratio of the pathogen, and the latent period. The author concentrates on the progeny/parent ratio - a subject not hitherto probed in detail in the literature - and shows how to determine the type of epidemic that can occur.

Download or read book Arbuscular Mycorrhizas Physiology and Function written by Hinanit Koltai and published by Springer Science & Business Media. This book was released on 2010-08-25 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the years since the first edition of “Arbuscular Mycorrhizas: Physiology and Function” was published, an exceptional proliferation of interest in mycorrhizal biology has developed. This has been associated with advances in different research disciplines such as genetics, genomics, proteomics, metabolomics and physiology, advances which have generated better insight into topics of mycorrhizal biology, including the mechanisms of host-mycorrhiza interactions pre- and post-penetration, the influence of the symbiosis on the host and its surroundings, and the evolution and diversity of mycorrhization. It therefore became necessary to both update and expand the book's coverage in this, its second edition.
