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 Mycotoxins written by Anne E. Desjardins and published by American Phytopathological Society. This book was released on 2006 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Also included is a thorough review of the molecular genetics of both trichothecene and fumonisin biosynthesis, presenting more than 15 years of molecular biological research in an accessible form. Part one then reviews the natural occurrence and toxicity of agriculturally important mycotoxins, with historical case studies of suspected mycotoxicoses in humans and animals. These chapters also contain updates on the molecular genetics of additional mycotoxins and the importance of mycotoxins in plant diseases. This useful reference presents concise descriptions of mycotoxin-producing Fusarium species, as defined by the most recent concepts of fungal species biology and evolution. Each species' report includes a risk assessment based on its mycotoxin profile, occurrence in food and feed crops, and association with human and animal mycotoxicoses. Data on species distribution, mycotoxin profiles, and animal toxicity facilitate risk assessment for food and feed safety.

Available in PDF, EPUB and Kindle. Book excerpt: In a sustainable agricultural system, legume crops are one of the essential components. However, improving the productivity of legume crops and improving their tolerance to adverse environments are essential tasks for plant biologists. This book includes nine comprehensive chapters addressing various aspects of legume crop biology, production and importance. There are several chapters on the adaptation of legumes to an adverse environment. Particular focus is provided on the sustainable production of legume crops under changing environments. This book will be useful for undergraduate and graduate students, teachers, and researchers, particularly from the field of Crop Science, Soil Science, Plant Breeding and Agronomy.

Download or read book Westcott s Plant Disease Handbook written by R. K. Horst and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1242 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was a compliment to me to be asked to prepare the fourth edition of Westcott's Plant Disease Handbook, and the decision to accept the responsi bility for the fourth edition and now the fifth edition was not taken lightly. The task has been a formidable one. I have always had a great respect professionally for Dr. Cynthia Westcott. That respect has grown considerably with the completion of the two editions. I now fully realize the tremendous amount of effort expended by Dr. Westcott in developing the Handbook. A book such as this is never finished, since one is never sure that everything has been included that should be. I would quote and endorse the words of Dr. Westcott in her preface to the first edition: "It is easy enough to start a book on plant disease. It is impossible to finish it. " This revision of the Handbook retains the same general format contained in the previous editions. The chemicals and pesticides regulations have been updated; a few taxonomic changes have been made in the bacteria, fungi, and mistletoes; the changing picture in diseases caused by viruses and/or viruslike agents has been described. A few new host plants have been added, and many recently reported diseases as well as previously known diseases listed now on new hosts have been included. In addition, photographs have been replaced where possible, and the color photograph section has been retained.
Download or read book Bacterial Wilt Disease written by Philippe Prior and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jointly published with INRA, Paris. Bacterial wilt, caused by Ralstonia solanacearum, is a very destructive plant disease that attacks over 450 different species, including many of the most important economic crop plants. Often endemic, the bacterium transmits through the soil, penetrates the plant root system and eventually causes irreversible wilting and death. This book summarizes the current information on bacterial wilt for both the basic research community and for concerned professionals who are faced with the disease in the field, offering the latest approaches to diagnosis and control of the disease. Emphasis is placed on integrated and biologically sustainable control methods. Also presented is the most recent genetic/biochemical research exploring the interaction between the bacterium and its plant host at the molecular level.
