Concern about the environmental consequences of the widespread use of pesticides has increased, and evidence of pesticide-resistant virus vectors have continued to emerge. This volume presents a timely survey of the mechanisms of plant resistance and examines current developments in breeding for resistance, with particular emphasis on advances in genetic engineering which allow for the incorporation of viral genetic material into plants. Discusses the mechanisms of innate resistance in strains of tobacco, tomato, and cowpea; various aspects of induced resistance, including the characterization and roles of the pathogenesis-related proteins; antiviral substances and their comparison with interferon; and cross-protection between plant virus strains. Also presents several papers which evaluate the status of genetic engineering as it relates to breeding resistant plants. Among these are discussions of the potential use of plant viruses as gene vectors, gene coding for viral coat protein, satellite RNA, and antisense RNA, and practical issues such as the durability of resistant crop plants in the field.
What happens when the old mass media/mass marketing model collapses and the Brave New World is unprepared to replace it? In this fascinating, terrifying, instructive and often hilarious book, Bob Garfield of NPR and Ad Age, chronicles the disintegration of traditional media and marketing but also travels five continents to discover how business can survive--and thrive--in a digitally connected, Post-Media Age. He calls this the art and science of Listenomics. You should listen, too.
Written by a leading Civil War historian and Pulitzer Prize winner, this text describes the social, economic, political, and ideological conflicts that led to a unique, tragic, and transitional event in American history. The third edition incorporates recent scholarship and addresses renewed areas of interest in the Civil War/Reconstruction era including the motivations and experiences of common soldiers and the role of women in the war effort.
Here is the story of the long interaction between humans, land, and climate in the American South. It is a tale of exploitation and erosion, of destruction, disease, and defeat, but also of the persistent search for knowledge and wisdom. It is a story whose villains were also its victims and sometimes its heroes. Ancient forces created the southern landscape, but, as Albert E. Cowdrey shows, humankind from the time of earliest habitation has been at work reshaping it. The southern Indians, far from being the "natural ecologists" of myth, radically transformed their environment by hunting and burning. Such patterns were greatly accelerated by the arrival of Europeans, who viewed the land as a commodity to be exploited for immediate economic benefit. Cowdrey documents not only the long decline but the painfully slow struggle to repair the damage of human folly. The eighteenth century saw widespread though ineffectual efforts to protect game and conserve the soil. In the nineteenth century the first hesitant steps were taken toward scientific flood control, forestry, wildlife protection, and improved medicine. In this century, the New Deal, the explosion in scientific knowledge, and the national environmental movement have spurred more rapid improvements. But the efforts to harness the South's great rivers, to save its wild species, and to avert serious environmental pollution have often had equivocal results. Originally published in 1983 and needed now more than ever, This Land, This South was the first book to explore the cumulative impact of humans on the southern landscape and its effect on them. In graceful and at times lyrical prose, Albert Cowdrey brings together a vast array of information. Now revised and updated, this important book should be read by every person concerned with the past, present, or future of the South.
