This anchor volume to the series Managing Global Genetic Resources examines the structure that underlies efforts to preserve genetic material, including the worldwide network of genetic collections; the role of biotechnology; and a host of issues that surround management and use. Among the topics explored are in situ versus ex situ conservation, management of very large collections of genetic material, problems of quarantine, the controversy over ownership or copyright of genetic material, and more.

In the United States, the critical task of preserving our plant genetic resources is the responsibility of the National Plant Germplasm System (NPGS). NPGS undergoes a thorough analysis in this book, which offers wide-ranging recommendations for equipping the agency to better meet U.S. needsâ€"and lead international conservation efforts. The book outlines the importance and status of plant genetic conservation and evaluates NPGS's multifaceted operations. Two options for revamping NPGS within the U.S. Department of Agriculture are included.

Ex situ preservation of germplasm for higher plant species has been accom plished using either seeds or clones, but storage of these under typical condi tions does not provide the extreme longevities that are needed to minimize risk of loss. Costs of maintenance and regeneration of stocks are also high. Systems that provide virtually indefinite storage should supplement existing methods and it is within this context that cryopreservation is presented. The use of low temperature preservation was initially more a concern of medicine and animal breeding, and was expanded to plants in the 1970s. Sur vival after cryogenic exposure has now been demonstrated for diverse plant groups including algae, bryophytes, fungi and higher plants. If survival is com monplace, then the eventual application is a cryopreservation system, whereby cells, tissues and organs are held indefinitely for use, often in the unforeseen future. The increasing interest and capabilities for application could not have occurred at a more opportune time since expanding human populations have placed unprecedented pressures on plant diversity. This book emphasizes cry opreservation of higher plants and was initially driven by the concern for loss of diversity in crops and the recognized need that this diversity would be essential for continued improvement of the many plants used by society for food, health and shelter. The interest in cryopreservation has been expanded by conservationists and their concerns for retaining, as much as possible, the diversity of natural populations. The need for cryopreservation, thus, is well established.

The long-term storage and maintenance of viable plant cells and organs is an area of active concern across the range of pure and applied plant sciences. In academic, government and commercial laboratories, the extended storage of propagules of one sort or another, with maximum protection of the genome from mutation and altered expression, is often a very necessary activity that can draw heavily on resources and effort. However, preservation per se is typically not an activity in its own right, but a facilitating technology that is part of a larger programme of work. Consequently, there are many laboratories that do not have the benefit of a specialist in storage technology, and have to delegate the responsibility to individuals, or teams, who are faced with a daunting learning curve. To maximise the chances of success, in the shortest possible time and with minimum losses, these researchers need sources of reference that are au thoritative and soundly based in practical experience.
