Available in PDF, EPUB and Kindle. Book excerpt: Resistance of soybean to brown stem rot (BSR), caused by Phialophora gregata (Allington and Chamberlain) W. Gams, has become an important aspect of soybean breeding programs in the north central United States. The discovery of variability of P. gregata isolates from different states has increased the interest in BSR research. The objectives of this study were to further investigate interactions between P. gregata and soybean by studying: (1) the inheritance of resistance to BSR in the soybean cultivar Asgrow A3733, (2) the effects of culturing the fungus on different sources of soybean media, and (3) the effects of field fertility levels on BSR development on soybean. The inheritance study showed a different genetic control for resistance to BSR than has been previously reported. The relatively large number of intermediate disease reaction types in progeny from crosses involving A3733 and susceptible parents indicates the presence of a minor or modifier gene. A genetic model was proposed based on one gene with a major effect (probably dominant) and a second gene with a minor effect for BSR resistance. This appears to be a unique source of resistance to BSR that can be incorporated into breeding programs along with other known sources of resistance. Culturing P. gregata on soybean stem agar and seed broth prepared from BSR-resistant or -susceptible soybean produced varying results. The use of certain resistant soybean as media source caused the pathogen to be much less aggressive. When susceptible soybean were used to prepare media for inoculum production, typical disease reactions were observed for BSR-resistant and susceptible soybean. Soybean plants grown on a low field fertility level had greater development of BSR stem symptoms on BSR-susceptible and resistant soybean as compared to being grown on a field with a high fertility level. Leaf symptoms are not observed every year and may appear too late in the growing season to be rated on early maturing soybean plants. Differences between resistant and susceptible soybean genotypes were greater in low fertility. Selection for BSR resistant plants in the field may be enhanced with conditions of low fertility.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the third in a series of volumes on major tropical and sub-tropical crops. These books aim to review the current state of the art in management of the total spectrum of pests and diseases which affect these crops in each major growing area using a multi-disciplinary approach. Soybean is economically the most important legume in the world. It is nutritious and easily digested, and is one of the richest and cheapest sources of protein. It is currently vital for the sustenance of many people and it will play an integral role in any future attempts to relieve world hunger. Soybean seed contains about 17% of oil and about 63% of meal, half of which is protein. Modern research has developed a variety of uses for soybean oil. It is processed into margarine, shortening, mayonnaise, salad creams and vegetarian cheeses. Industrially it is used in resins, plastics, paints, adhesives, fertilisers, sizing for cloth, linoleum backing, fire extinguishing materials, printing inks and a variety of other products. Soybean meal is a high-protein meat substitute and is used in the developed countries in many processed foods, including baby foods, but mainly as a feed for livestock. Soybean (Glycine max), which evolved from Glycine ussuriensis, a wild legume native to northern China, has been known and used in China since the eleventh century Be. It was introduced into Europe in the eighteenth century and into the United States in 1804 as an ornamental garden plant in Philadelphia.

Download or read book Molecular Identification of Fungi written by Youssuf Gherbawy and published by Springer Science & Business Media. This book was released on 2010-03-03 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fungi enjoy great popularity in pharmaceutical, agricultural, and biotechnological applications. Recent advances in the decipherment of whole fungal genomes promise an acceleration of these trends. This timely book links scientists from different parts of the world who are interested in the molecular identification of fungi combined with the exploration of the fungal biodiversity in different ecosystems. It provides a compendium for scientists who rely on a rapid and reliable detection of fungal specimens in environmental as well as clinical resources in order to ensure the benefit of industrial and clinical applications. Chapters focus on the opportunities and limits of the molecular marker-mediated identification of fungi. Various methods, procedures and strategies are outlined. Furthermore, the book offers an update of the current progress in the development of fungal molecular techniques, and draws attention to potential and associated problems, as well as integrating theory and practice.
Download or read book Current Trends in Plant Disease Diagnostics and Management Practices written by Pradeep Kumar and published by Springer. This book was released on 2016-04-28 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant diseases play an important role on our daily lives. Most of plant diseases are visible and are caused by biotic and/or abiotic factors. Symptoms are usually the results of a morphological change, alteration or damage to plant tissue and/or cells due to an interference of the plant’s metabolism. All basic structures of vascular plants are subject to attack by pathogens. The failure in accurate disease diagnosis and management may lead to huge losses in plant production and related commodities, which causes nutritional food scarcity. Typically, the appearance of a biotic symptom will indicate the relatively late stage of an infection and/or colonization of a pathogen. Expert detection, accurate diagnosis, and timely management play a significant role in keeping plants free from pathogens. In this book expert scholars share their research knowledge and key literature which are vital toward the diagnosis of plant diseases across the globe, addressing traditional plant pathology techniques, as well as advanced molecular diagnostic approach.

This book was released on 2010-10-20 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of a crop, and therefore its health, is always the result of interplay between biological and environmental factors, as influenced by human agency. In other words, crop health is a highly complex affair. This book is concerned with only one group of agents affecting crop health, the pathogens, and not with animal pests or direct effects of physiological or weather factors. Even within this one group, however, the interaction of causal agents with environmental and biotic factors is highly complex. No less complex is the effect of cultural practices on the crop and its health. There is probably no major practice that does not affect diverse facets of crop growth, which in turn affects crop/pathogen relationships. Thus tillage se quentially affects depth and rate of root development, hence nutrient uptake, hence general plant size and habit as well as crop climate and crop susceptibility. Irri gation affects all these parameters, and facilitates crop growth under diverse macro climatic conditions, with all the ensuing implications for disease development. In this book an attempt is made to superimpose one set of complexities, the cul tural practices, on another such set, crop health. This may seem overambitious, not to say foolhardy, unless we remember that it has been done by farmers, consciously or unconsciously, ever since the beginnings of agriculture. We are here chiefly try ing to rationalize traditional practices, review modern research on the development of further practices, and assess the place of the latter in integrated disease control.
