Book excerpt: Excerpt from Annals of Applied Biology, 1933, Vol. 3: The Official Organ of the Association of Economic Biologist In 1914 complaints were received by the South-Eastern Agricultural College at Wye of serious diseases affecting the plantations of fig-trees in the district of Sompting, Sussex. On a visit being paid in May 1914 to the affected plantations, fig-trees of all ages were found to be suffering from fungous attacks of two kinds. A species of Botrytis was found on the tips of the branches, apparently gradually killing them back. This disease is still under observation and will be the subject of a further communication. The second disease which occurred was a "canker" of the branches. In some cases, where old trees were badly attacked, numerous "cankers" were found, both on the younger branches, and on the old, main branches, often quite close to the ground. With the progress of the disease, the "canker" area enlarges, until the tissues extending through the branch are killed, with the result that the parts above die. With the successive removal of these "cankered" branches the productiveness of the tree is soon seriously impaired. The majority of the trees in these plantations are of the variety known as "Brown Turkey," but a few are of the "White Marseilles" variety. It was obvious from the effects produced that this "canker" disease was of serious economic importance; it was the opinion of the farmer of the largest fig-plantations that unless the cause of the disease could be discovered and a remedy devised the whole future of Fig-growing in that district was threatened. The constant occurrence of a fungus with pycnidial fructifications on the cankered area was noted in the field, and the following notes were made from the examination of the material collected.

Available in PDF, EPUB and Kindle. Book excerpt: We normally think of viruses in terms of the devastating diseases they cause, from smallpox to AIDS. But in The Life of a Virus, Angela N. H. Creager introduces us to a plant virus that has taught us much of what we know about all viruses, including the lethal ones, and that also played a crucial role in the development of molecular biology. Focusing on the tobacco mosaic virus (TMV) research conducted in Nobel laureate Wendell Stanley's lab, Creager argues that TMV served as a model system for virology and molecular biology, much as the fruit fly and laboratory mouse have for genetics and cancer research. She examines how the experimental techniques and instruments Stanley and his colleagues developed for studying TMV were generalized not just to other labs working on TMV, but also to research on other diseases such as poliomyelitis and influenza and to studies of genes and cell organelles. The great success of research on TMV also helped justify increased spending on biomedical research in the postwar years (partly through the National Foundation for Infantile Paralysis's March of Dimes)—a funding priority that has continued to this day.

This book was released on 2010-07-01 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now established worldwide as the standard guide to the recognition and understanding of the causes of deterioration in temperate and tropical fruits and vegetables, these two superbly illustrated full-colour volumes deal clearly, concisely and systematically with each of the main diseases and disorders, emphasising those of importance to international trade. Dr Snowdon has designed each volume to be used in two different ways: 1. Full colour photographs and practical text provide the basis for preliminary identification by the owner or surveyor. 2. Using the microscope drawings and references, diagnosis can then be confirmed or modified by a specialist.

Book excerpt: Plant Breeding Reviews presents state-of-the-art reviews on plant genetics and the breeding of all types of crops by both traditional means and molecular methods. Many of the crops widely grown today stem from a very narrow genetic base; understanding and preserving crop genetic resources is vital to the security of food systems worldwide. The emphasis of the series is on methodology, a fundamental understanding of crop genetics, and applications to major crops.
