Book excerpt: One of the classic host-pathogen relationships in plant pathology is between the common barberry, Berberis vulgaris, and Puccinia graminis, the cause of stem rust, a destructive disease of small grains. As the alternate host of P. graminis, the barberry is the key in the sexual stage of the pathogen's life cycle. The combination of extensive small grains production and widespread cultivation of the common barberry in the north central United States resulted in major stem rust epidemics by the late 1800s and early 1900s. In 1918, the Barberry Eradication Program was initiated by the U.S. Department of Agriculture in cooperation with important small grain producing states. Before the termination of the program in the late 1970s, more than 500 million barberry bushes were destroyed. Since the end of the program, however, scientists have voiced concerns about the potential for barberry to reemerge as a source of inoculum and of new genetic forms. The objectives of this research were to examine the history of barberry eradication in Minnesota, to determine whether barberry has reemerged on sites in Minnesota and what effect this reemergence may have on future stem rust epidemics. An evaluation of archival records revealed that the origin of the Barberry Eradication Program was in reaction to successive stem rust epidemics and concerns over production shortages during World War I. The program that developed after 1918 was an unprecedented collaborative effort among federal-state agencies, land-grant colleges, and agricultural industry. Initial survey work was focused on the removal of barberry bushes in cities, towns, and rural planted sites; priorities shifted and procedures changed with the discovery of large numbers of escaped bushes, particularly in southeastern Minnesota. More than one million barberry bushes were destroyed in Minnesota between 1918-1990. A field survey of 72 of the approximately 1200 active sites in Minnesota was conducted. Active sites were define.

Available in PDF, EPUB and Kindle. Book excerpt: Wheat rust diseases have been among the most devastating of all plant diseases since biblical times. Now that nearly a half century has passed without a significant outbreak in the world's major wheat- producing regions, forward writer Nobel laureate Norman Borlaug cautions against complacency. Four contributed chapters examine how the science of plant pathology has responded to such challenges as stem rust of wheat epidemics in the North American Great Plains in the first half of the 20th century, and common barberry as an insidious spreader of black stem rust. Includes photos of plant pathologists and their research in the field (literally). c. Book News Inc.
Download or read book Plant Relationships written by Barry Scott and published by Springer Nature. This book was released on 2022-12-08 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fully revised 3rd edition provides a comprehensive overview of the biology of fungi associated with plants. Since the publication of the 2nd Edition in 2009, tremendous new knowledge has been gained in the field of fungal-plant interactions, which is reflected in the contributions of this book. World-leading scientists in the field provide authoritative insights into fungal-plant interactions covering the following main topics: Mutualistic and pathogenic fungal-plant interactions in natural and agricultural ecosystems Sensing and signalling in fungus-plant interactions Regulation of fungal gene expression and development Fungal genomes and evolution Global pandemics caused by fungal pathogens and their implications for food security This volume will be of great interest to both specialists and generalists. It is an indispensable resource for researchers, lecturers and students in microbiology, mycology, and plant sciences, as well as agriculture and biotechnology.

This book was released on 2015-02-12 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores problems in the history of science at the intersection of life sciences and agriculture, from the mid-eighteenth to the mid-twentieth century. Taking a comparative national perspective, the book examines agricultural practices in a broad sense, including the practices and disciplines devoted to land management, forestry, soil science, and the improvement and management of crops and livestock. The life sciences considered include genetics, microbiology, ecology, entomology, forestry, and deal with US, European, Russian, Japanese, Indonesian, Chinese contexts. The book shows that the investigation of the border zone of life sciences and agriculture raises many interesting questions about how science develops. In particular it challenges one to re-examine and take seriously the intimate connection between scientific development and the practical goals of managing and improving – perhaps even recreating – the living world to serve human ends. Without close attention to this zone it is not possible to understand the emergence of new disciplines and transformation of old disciplines, to evaluate the role and impact of such major figures of science as Humboldt and Mendel, or to appreciate how much of the history of modern biology has been driven by national ambitions and imperialist expansion in competition with rival nations.
