Pathogen and Microbial Contamination Management in Micropropagation


Book Description

This book is based mainly on invited and offered papers presented at the Second International Symposium on Bacterial and Bacteria-like Contaminants of Plant Tissue Cultures held at University College, Cork, Ireland in September 1996, with additional invited papers. The First International Symposium on Bacterial and Bacteria-like Contaminants of Plant Tissue Cultures was held at the same venue in 1987 and was published as Acta Horticulturae volume 225, 1988. In the intervening years there have been considerable advances in both plant disease diagnostics and in the development of structured approaches to the management of disease and microbial contamination in micropropagation. These approaches have centred on attempts to separate, spatially, the problems of disease transmission and laboratory contamination. Disease-control is best achieved by establishing pathogen-free cultures while laboratory contamination is based on subsequent good working practice. Control of losses due to pathogens and microbial contamination in vitro addresses, arguably, the most importance causes of losses in the industry; nevertheless, losses at and post establishment can also be considerable due to poor quality microplants or micro-shoots. In this symposium, a holistic approach to pathogen and microbial contamination control is evident with the recognition that micropropagators must address pathogen and microbial contamination in vitro, and diseases and microplant failure at establishment. There is increasing interest in establishing beneficial bacterial and mycorrhizal association with microplants in vitro and in vivo.




A History of Cornell


Book Description

Cornell University is fortunate to have as its historian a man of Morris Bishop's talents and devotion. As an accurate record and a work of art possessing form and personality, his book at once conveys the unique character of the early university—reflected in its vigorous founder, its first scholarly president, a brilliant and eccentric faculty, the hardy student body, and, sometimes unfortunately, its early architecture—and establishes Cornell's wider significance as a case history in the development of higher education. Cornell began in rebellion against the obscurantism of college education a century ago. Its record, claims the author, makes a social and cultural history of modern America. This story will undoubtedly entrance Cornellians; it will also charm a wider public. Dr. Allan Nevins, historian, wrote: "I anticipated that this book would meet the sternest tests of scholarship, insight, and literary finish. I find that it not only does this, but that it has other high merits. It shows grasp of ideas and forces. It is graphic in its presentation of character and idiosyncrasy. It lights up its story by a delightful play of humor, felicitously expressed. Its emphasis on fundamentals, without pomposity or platitude, is refreshing. Perhaps most important of all, it achieves one goal that in the history of a living university is both extremely difficult and extremely valuable: it recreates the changing atmosphere of time and place. It is written, very plainly, by a man who has known and loved Cornell and Ithaca for a long time, who has steeped himself in the traditions and spirit of the institution, and who possesses the enthusiasm and skill to convey his understanding of these intangibles to the reader." The distinct personalities of Ezra Cornell and first president Andrew Dickson White dominate the early chapters. For a vignette of the founder, see Bishop's description of "his" first buildings (Cascadilla, Morrill, McGraw, White, Sibley): "At best," he writes, "they embody the character of Ezra Cornell, grim, gray, sturdy, and economical." To the English historian, James Anthony Froude, Mr. Cornell was "the most surprising and venerable object I have seen in America." The first faculty, chosen by President White, reflected his character: "his idealism, his faith in social emancipation by education, his dislike of dogmatism, confinement, and inherited orthodoxy"; while the "romantic upstate gothic" architecture of such buildings as the President's house (now Andrew D. White Center for the Humanities), Sage Chapel, and Franklin Hall may be said to "portray the taste and Soul of Andrew Dickson White." Other memorable characters are Louis Fuertes, the beloved naturalist; his student, Hugh Troy, who once borrowed Fuertes' rhinoceros-foot wastebasket for illicit if hilarious purposes; the more noteworthy and the more eccentric among the faculty of succeeding presidential eras; and of course Napoleon, the campus dog, whose talent for hailing streetcars brought him home safely—and alone—from the Penn game. The humor in A History of Cornell is at times kindly, at times caustic, and always illuminating.

Courage in a Dangerous World


Book Description

Dozens of books have been written about Eleanor Roosevelt, but her own writings are largely confined to the Roosevelt archives in Hyde Park. Courage in a Dangerous World allows her own voice again to be heard. Noted Eleanor Roosevelt scholar Allida M. Black has gathered more than two hundred columns, articles, essays, and speeches culled from archives whose pages number in the millions, tracing her development from timorous columnist to one of liberalism's most outspoken leaders. From "My Day" newspaper columns about Marian Anderson and excerpts from Moral Basis of Democracy and This Troubled World to speeches and articles on the Holocaust and McCarthyism, this anthology provides readers with the tools to reconstruct the politics of a woman who redefined American liberalism and democratic reform. Arranged chronologically and by topic, the volume covers the New Deal years, the White House years, World War II at home and abroad, the United Nations and human rights, the Cold War, the civil rights movement, the resurgence of feminism, and much more. In addition, the collection features excerpts from Eleanor Roosevelt's correspondence with Franklin Delano Roosevelt, Harry S. Truman, Adlai Stevenson, J. Edgar Hoover, John F. Kennedy, and ordinary Americans. The volume features a collection of 30 rare photographs. A comprehensive bibliography of Eleanor Roosevelt's articles serves as a valuable resource, providing a link to the issues she held dear, many of which are still hotly debated today.
