Well-managed genebanks both safeguard genetic diversity and make it available to breeders. The Genebank Standards for Plant Genetic Resources for Food and Agriculture lay down the procedures for conserving plant genetic resources.These voluntary Standards set the benchmark for current scientific and technical best practices, and support the key international policy instruments for the conservation and use of plant genetic resources.
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 re...
Genes in the Field: Conserving Plant Diversity on Farms is a comprehensive collection of papers focusing on agricultural conservation and diversity issues throughout the world. Recently, regional and local farm seed variety has been reduced because of increased population, agricultural science and technology and the integration of the world's many diverse cultures. Because of this, diversity on individual farms across wide regions is threatened by modern crop varieties that have been bred for broad adaptation, resistance to disease, and other risk factors such as their ability to better use water, fertilizer, and higher yields. The concern of the farmers to maintain production levels and income often seems incompatible with those whose focus is on the maintenance of viable and sustainable ecosystems and maintaining genetic diversity. Exploring and understanding these different concerns is an essential starting point for answering some of the key questions about the implementation of "on farm" conservation and the role of local cultivators in sustainable development.
The vast and exciting Brazilian flora biodiversity is still underexplored. Several research groups are devoted to the study of the chemical structure richness found in the different Biomes. This volume presents a comprehensive account of the research collated on natural products produced from Brazilian medicinal plants and focuses on various aspects of the field. The authors describe the key natural products and their extracts with emphasis upon sources, an appreciation of these complex molecules and applications in science. Many of the extracts are today associated with important drugs, nutrition products, beverages, perfumes, cosmetics and pigments, and these are highlighted. Key Features: Presents Brazilian biodiversity: its flora, its people, and its research Describes the emergence of natural products research in Brazil Emphasizes the increasing global interests in botanical drugs Aids the international natural product communities to better understand the herbal resources in Brazil Discusses Brazilian legislation to work with native plants
Community seed banks first appeared towards the end of the 1980s, established with the support of international and national non-governmental organizations. This book is the first to provide a global review of their development and includes a wide range of case studies. Countries that pioneered various types of community seed banks include Bangladesh, Brazil, Ethiopia, India, Nepal, Nicaragua, the Philippines and Zimbabwe. In the North, a particular type of community seed bank emerged known as a seed-savers network. Such networks were first established in Australia, Canada, the UK and the USA before spreading to other countries. Over time, the number and diversity of seed banks has grown. In...
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
