A seed bank stores seeds to preserve genetic diversity; hence it is a type of gene bank. There are many reasons to store seeds. One is to preserve the genes that plant breeders need to increase yield, disease resistance, drought tolerance, nutritional quality, taste, etc. of crops. Another is to forestall loss of genetic diversity in rare or imperiled plant species in an effort to conserve biodiversity ex situ. Many plants that were used centuries ago by humans are used less frequently now; seed banks offer a way to preserve that historical and cultural value. Collections of seeds stored at constant low temperature and low moisture are guarded against loss of genetic resources that are otherwise maintained in situ or in field collections. These alternative "living" collections can be damaged by natural disasters, outbreaks of disease, or war. Seed banks are considered seed libraries, containing valuable information about evolved strategies to combat plant stress, and can be used to create genetically modified versions of existing seeds. The work of seed banks often span decades and even centuries. Most seed banks are publicly funded and seeds are usually available for research that benefits the public.
The International Treaty on Plant Genetic Resources for Food and Agriculture, is a comprehensive international agreement in harmony with the Convention on Biological Diversity, which aims at guaranteeing food security through the conservation, exchange and sustainable use of the world's plant genetic resources for food and agriculture (PGRFA), the fair and equitable benefit sharing arising from its use, as well as the recognition of farmers' rights. It was signed in 2001 in Madrid, and entered into force on 29 June 2004.
The International Maize and Wheat Improvement Center is a non-profit research-for-development organization that develops improved varieties of wheat and maize with the aim of contributing to food security, and innovates agricultural practices to help boost production, prevent crop disease and improve smallholder farmers' livelihoods. CIMMYT is one of the 15 CGIAR centers. CIMMYT is known for hosting the world's largest maize and wheat genebank at its headquarters in Mexico.
CGIAR is a global partnership that unites international organizations engaged in research about food security. CGIAR research aims to reduce rural poverty, increase food security, improve human health and nutrition, and sustainable management of natural resources.
The International Center for Tropical Agriculture is an international research and development organization dedicated to reducing poverty and hunger while protecting natural resources in developing countries. It is based in Palmira, Colombia, where it employs over 300 scientists.
Agricultural biodiversity or agrobiodiversity is a subset of general biodiversity pertaining to agriculture. It can be defined as "the variety and variability of animals, plants and micro-organisms at the genetic, species and ecosystem levels that sustain the ecosystem structures, functions and processes in and around production systems, and that provide food and non-food agricultural products.” It is managed by farmers, pastoralists, fishers and forest dwellers, agrobiodiversity provides stability, adaptability and resilience and constitutes a key element of the livelihood strategies of rural communities throughout the world. Agrobiodiversity is central to sustainable food systems and sustainable diets. The use of agricultural biodiversity can contribute to food security, nutrition security, and livelihood security, and it is critical for climate adaptation and climate mitigation.
Germplasm refers to genetic resources such as seeds, tissues, and DNA sequences that are maintained for the purpose of animal and plant breeding, conservation efforts, agriculture, 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. 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, food security, and conservation efforts.
The Africa Rice Center (AfricaRice), formerly known as the West Africa Rice Development Association (WARDA), is a pan-African intergovernmental association and a CGIAR Research organization, currently headquartered in Abidjan, Côte d'Ivoire. AfricaRice is an agricultural research center that was constituted in 1971 by 11 West African countries. By 2023, the center counted 28 African member states. Since 1986, AfricaRice has been one of the 15 specialized research centers of CGIAR.
The Svalbard Global Seed Vault is a secure backup facility for the world's crop diversity on the Norwegian island of Spitsbergen in the remote Arctic Svalbard archipelago. The Seed Vault provides long-term storage of duplicates of seeds conserved in genebanks around the world. This provides security of the world's food supply against the loss of seeds in genebanks due to mismanagement, accident, equipment failures, funding cuts, war, sabotage, disease and natural disasters. The Seed Vault is managed under terms spelled out in a tripartite agreement among the Norwegian government, the Crop Trust, and the Nordic Genetic Resource Center (NordGen).
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. 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 °C in liquid nitrogen, being placed in artificial ecosystems, or put in controlled nutrient media.
The Crop Trust, officially known as the Global Crop Diversity Trust, is an international nonprofit organization with a secretariat in Bonn, Germany. Its mission is to conserve and make available the world's crop diversity for food security.
The International Center for Agricultural Research in the Dry Areas (ICARDA), a member of CGIAR, supported by the CGIAR Fund, is a non-profit agricultural research institute that aims to improve the livelihoods of the resource-poor across the world's dry areas.
Morgan Carrington "Cary" Fowler Jr. is an American agriculturalist and the former executive director of the Crop Trust, currently serving as U.S. Special Envoy for Global Food Security.
Bioversity International is a global research-for-development organization that delivers scientific evidence, management practices and policy options to use and safeguard agricultural biodiversity to attain global food- and nutrition security, working with partners in low-income countries in different regions where agricultural biodiversity can contribute to improved nutrition, resilience, productivity and climate change adaptation.
Crop diversity or crop biodiversity is the variety and variability of crops, plants used in agriculture, including their genetic and phenotypic characteristics. It is a subset of a specific element of agricultural biodiversity. Over the past 50 years, there has been a major decline in two components of crop diversity; genetic diversity within each crop and the number of species commonly grown.
The World Vegetable Center (WorldVeg), previously known as the Asian Vegetable Research and Development Center (AVRDC), is an international, nonprofit institute for vegetable research and development. It was founded in 1971 in Shanhua, southern Taiwan, by the Asian Development Bank, Taiwan, South Korea, Japan, the Philippines, Thailand, the United States and South Vietnam.
John Trevor Williams was a British plant geneticist who was instrumental in the creation of plant gene banks.
The Nordic Genetic Resource Center is a plant, farm animal and forest conservation, gene resource guardian, and sustainable use organization under and primarily financed by the Nordic Council of Ministers, and is headquartered in Alnarp, near Malmö, in southern Sweden. NordGen's primary mission is "securing the broad diversity of genetic resources linked to food and agriculture" through "conservation and sustainable use, solid documentation and information work and international agreements".
Plant genetic resources describe the variability within plants that comes from human and natural selection over millennia. Their intrinsic value mainly concerns agricultural crops.
Chin Hoong Fong was a seed scientist who pioneered the storage of recalcitrant seeds in the 1970s.
