A seed bank also seedbank or seeds 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 have available the genes that plant breeders need to increase yield, disease resistance, drought tolerance, nutritional quality, taste, etc. 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 spans decades and even centuries. Most seed banks are publicly funded and seeds are usually available for research that benefits the public. Seeds are living creatures and keeping them viable over the long term requires adjusting storage moisture and temperature appropriately. As they mature on the mother plant, many seeds attain an innate ability to survive drying. The level of dryness and coldness depends mostly on the longevity that is required and the investment in infrastructure that is affordable. Research from the s showed that there is a limit to the beneficial effect of drying or cooling, so it must not be overdone. Understanding the effect of water content and temperature on seed longevity, the Food and Agriculture division of the United Nations and a consultancy group called Bioversity International developed a set of standards for international seed banks \\\\\\\\\\\\\\\\\[1\\\\\\\\\\\\\\\\\] to preserve seed longevity. Seeds from our most important species - corn, wheat, rice, soybean, pea, tomato, broccoli, melon, sunflower, etc. However, there are many species that produce seeds that do not survive the drying or low temperature of conventional storage protocols. These species must be stored cryogenically. Seeds of citrus fruits, coffee, avocado, cocoa, coconut, papaya, oak, walnut and willow are a few examples of species that should be preserved cryogenically. Like everything, seeds eventually degrade with time. It is hard to predict when seeds lose viability and so most reputable seed banks monitor germination potential during storage. When seed germination percentage decreases below a prescribed amount, the seeds need to be replanted and fresh seeds collected for another round of long-term storage. In-situ conservation of seed-producing plant species is another conservation strategy. In-situ conservation involves the creation of National Parks , National Forests , and National Wildlife Refuges as a way of preserving the natural habitat of the targeted seed-producing organisms. In-situ conservation of agricultural resources is performed on-farm. This also allows the plants to continue to evolve with their environment through natural selection. An arboretum stores trees by planting them at a protected site. A less expensive, community-supported seed library can save local genetic material. The phenomenon of seeds remaining dormant within the soil is well known and documented Hills and Morris Comparison tables of seed density and diversity are presented for the boreal and deciduous forest types and the research that has been conducted is discussed. This review includes detailed discussions of: Seeds may be viable for hundreds and even thousands of years. The oldest carbon -dated seed that has grown into a viable plant was a Judean date palm seed about 2, years old, recovered from excavations at the palace of Herod the Great in Israel. In February , Russian scientists announced they had regenerated a narrow leaf campion Silene stenophylla from a 32,year-old seed. Seed tissue was grown in test tubes until it could be transplanted to soil. This exemplifies the long-term viability of DNA under proper conditions. Conservation efforts such as seed banks are expected to play a greater role as climate change progresses. Seed banks offer communities a source of climate-resilient seeds to withstand changing local climates. As challenges arise from climate change, community based seed banks can improve access to a diverse selection of locally adapted crops while also enhancing indigenous understandings of plant management such as seed selection, treatment, storage, and distribution. There are about 6 million accessions, or samples of a particular population, stored as seeds in about 1, genebanks throughout the world as of From Wikipedia, the free encyclopedia.
