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.
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 Plant Diseases written by J. E. Van Der Plank and published by Elsevier. This book was released on 2013-10-22 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Diseases: Epidemics and Control provides a description of the methods of epidemiological analysis based on infection rates and the relation between the amount of inoculum and the amount of disease it produces. The book shows how to study the increase of pathogen populations and the epidemiological strategy to be adopted to control the epidemic of plant diseases. The text covers the calculation of the logarithmic increase of disease; use of epidemiology in the study of control; forms of sanitation; the use of resistant plant varieties; and the design of field experiments. Plant pathologists and breeders, agriculturists, horticulturists, research workers, teachers, and students will find the text invaluable.
