Genetic Resources
Genetic resources are genetic material of actual or potential value, where genetic material means any material of plant, animal, microbial or other origin containing functional units of heredity. Genetic resources is one of the three levels of biodiversity defined by the Convention on Biological Diversity in Rio, 1992. Examples * Animal genetic resources for food and agriculture *Forest genetic resources *Germplasm, genetic resources that are preserved for various purposes such as breeding, preservation, and research * Plant genetic resources See also *Cryoconservation of animal genetic resources, a strategy to preserve genetic resources cryogenically * Commission on Genetic Resources for Food and Agriculture, the only permanent intergovernmental body that addresses biological diversity for food and agriculture *International Treaty on Plant Genetic Resources for Food and Agriculture, an international agreement to promote sustainable use of the world's plant genetic resources * ...

Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (''genetic variability''), species (''species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convention On Biological Diversity
The Convention on Biological Diversity (CBD), known informally as the Biodiversity Convention, is a multilateral treaty. The Convention has three main goals: the conservation of biological diversity (or biodiversity); the sustainable use of its components; and the fair and equitable sharing of benefits arising from genetic resources. Its objective is to develop national strategies for the conservation and sustainable use of biological diversity, and it is often seen as the key document regarding sustainable development. The Convention was opened for signature at the Earth Summit in Rio de Janeiro on 5 June 1992 and entered into force on 29 December 1993. The United States is the only UN member state which has not ratified the Convention. It has two supplementary agreements, the Cartagena Protocol and Nagoya Protocol. The Cartagena Protocol on Biosafety to the Convention on Biological Diversity is an international treaty governing the movements of living modified organisms ...

Forest Genetic Resources
Forest genetic resources or forest tree genetic resources are genetic resources (i.e., genetic material of actual or future value) of forest shrub and tree species. Forest genetic resources are essential for forest-depending communities who rely for a substantial part of their livelihoods on timber and non-timber forest products (for example fruits, gums and resins) for food security, domestic use and income generation. These resources are also the basis for large-scale wood production in planted forests to satisfy the worldwide need for timber and paper. Genetic resources of several important timber, fruit and other non-timber tree species are conserved ex situ in genebanks or maintained in field collections. Nevertheless, in situ conservation in forests and on farms is in the case of most tree species the most important measure to protect their genetic resources. Understanding diversity A better understanding of the diversity of these species is crucial for their sustainable us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germplasm
Germplasm are living genetic resources such as seeds or tissues that are maintained for the purpose of animal and plant breeding, preservation, and other research uses. These resources may take the form of seed collections stored in seed banks, trees growing in nurseries, animal breeding lines maintained in animal breeding programs or gene banks, etc. Germplasm collections can range from collections of wild species to elite, domesticated breeding lines that have undergone extensive human selection. Germplasm collection is important for the maintenance of biological diversity and food security.

Cryoconservation Of Animal Genetic Resources
Cryoconservation of animal genetic resources is a strategy wherein samples of animal genetic materials are preserved cryogenically."Cryoconservation of Animal Genetic Resources", Rep. Rome: Food and Agriculture Organization of the United Nations, 2012. FAO Animal Production and Health Guidelines No. 12. Print. Animal genetic resources, as defined by the Food and Agriculture Organization of the United Nations, are "those animal species that are used, or may be used, for the production of food and agriculture, and the populations within each of them. These populations within each species can be classified as wild and feral populations, landraces and primary populations, standardised breeds, selected lines, varieties, strains and any conserved genetic material; all of which are currently categorized as Breeds." Genetic materials that are typically cryogenically preserved include sperm, oocytes, embryos and somatic cells.Mazur, P., S.p Leibo, and G. E. Seidel.Cryopreservation of th ...

Gene Bank
Gene banks are a type of biorepository that preserves genetic material. For plants, this is done by in vitro storage, freezing cuttings from the plant, or stocking the seeds (e.g. in a seedbank). For animals, this is done by the freezing of sperm and eggs in zoological freezers until further need. With corals, fragments are taken and stored in water tanks under controlled conditions. Genetic material in a 'gene bank' is preserved in a variety of ways, such as freezing at -196° Celsius in liquid nitrogen, being placed in artificial ecosystems, and put in controlled nutrient mediums. Accession is the common term given to an individual sample in a gene bank, such as a distinct species or variety. In plants, it is possible to unfreeze the material and propagate it. However, in animals, a living female is required for artificial insemination. While it is often difficult to use frozen animal sperm and eggs, there are many examples of it being done successfully.

Genetic Diversity
Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species, it ranges widely from the number of species to differences within species and can be attributed to the span of survival for a species. It is distinguished from '' genetic variability'', which describes the tendency of genetic characteristics to vary. Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele. The population will continue for more generations because of the success of these individuals. The academic field of population genetics includes several hypotheses and theories regarding genetic diversity. The neutral theory of evolution proposes that diversity is the result of the accumulation of neutral substitutio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The State Of The World's Animal Genetic Resources For Food And Agriculture
''The State of the World's Animal Genetic Resources for Food and Agriculture'' is a major report on the genetic resources of breeds of farm livestock in the world. It was published by the Food and Agriculture Organization of the United Nations (FAO) in 2007. It covers mammalian and avian domestic livestock breeds, but does not include fish or honey bees and other invertebrates. It is based on information submitted to the FAO, in the form of reports of participating countries, thematic studies prepared by experts and data on individual breeds submitted to DAD-IS. An annex to the report, the ''List of breeds documented in the Global Databank for Animal Genetic Resources'', gives an estimate of conservation status The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservatio ... for all breeds fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
