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.
The recent development of ideas on biodiversity conservation was already being considered almost three-quarters of a century ago for crop plants and the wild species related to them, by the Russian geneticist N.!. Vavilov. He was undoubtedly the first scientist to understand the impor tance for humankind of conserving for utilization the genetic diversity of our ancient crop plants and their wild relatives from their centres of diversity. His collections showed various traits of adaptation to environ mental extremes and biotypes of crop diseases and pests which were unknown to most plant breeders in the first quarter of the twentieth cen tury. Later, in the 1940s-1960s scientists began to realize that the pool of genetic diversity known to Vavilov and his colleagues was beginning to disappear. Through the replacement of the old, primitive and highly diverse land races by uniform modem varieties created by plant breed ers, the crop gene pool was being eroded. The genetic diversity of wild species was equally being threatened by human activities: over-exploita tion, habitat destruction or fragmentation, competition resulting from the introduction of alien species or varieties, changes and intensification of land use, environmental pollution and possible climate change.
The papers included in this Special Issue address a variety of important aspects of plant biodiversity and genetic resources, including definitions, descriptions, and illustrations of different components and their value for food and nutrition security, breeding, and environmental services. Furthermore, comprehensive information is provided regarding conservation approaches and techniques for plant genetic resources, policy aspects, and results of biological, genetic, morphological, economic, social, and breeding-related research activities. The complexity and vulnerability of (plant) biodiversity and its inherent genetic resources, as an integral part of the contextual ecosystem and the human web of life, are clearly demonstrated in this Special Issue, and for several encountered problems and constraints, possible approaches or solutions are presented to overcome these.
A practical guide that covers both in situ and ex situ techniques for plant diversity conservation The conservation and sustainable use of plant genetic resources is of increasing importance globally. Plant Conservation Genetics addresses this issue by providing an extensive overview of this emerging area of science, exploring various pr
Advances in molecular and cell biology have led to the development of a whole range of techniques for manipulating genomes, collectively termed "biotechnology". Although much of the focus in the plant sciences has been on the direct manipulation of plant genomes, biotechnology has also catalyzed a renewed emphasis on the importance of biological and genetic diversity and its conservation. The methods of biotechnology now permit a greater understanding of both species and genetic diversity in plants, the mechanisms by which that variation is generated in nature, and the significance of that variation in the adaptation of plants to their environment. They allow the development of rapid methods for screening germplasm for specific characters and promote more effective conservation strategies by defining the extent of genetic diversity. Tissue culture-based techniques are available for conserving germplasm that cannot be maintained by more traditional methods. Also sophisticated informatics systems enable information on plant genetics and molecular biology to be cross-related to systematic, ecological and other data through international networks.
Cryopreservation has proven to be an important tool for the storage and conservation of plant genetic resources. This book is a unique resource for plant scientists, providing more than 100 ready-to-use cryopreservation protocols for plant types from algae and bryophytes to a range of flowering plants. It includes techniques for diverse plant parts such as dormant buds, pollen, and apical meristems and for cell types such as suspension and callus cultures.
These guidelines present the basic concepts involved in the development and implementation of in vivo conservation plans for animal genetic resources for food and agriculture. The guidelines are intended for use by policy-makers in the management of animal genetic resources, managers of animal breeding organizations, persons responsible for training in management of animal genetic resources and any other stakeholders with leading roles in designing and implementing in vivo conservation programmes for animal genetic resources. Although individual breeders and livestock keepers are not the direct target audience, the guidelines include background information that is relevant for all stakeholders involved in planning conservation programmes.
