National Gene bank (IPR)

Gene bank? Gene banks are a type of biorepository that preserves genetic material. A collection of seed plants, tissue cultures, etc. from potentially useful species, especially species containing genes of significance to the breeding of crops. In plants this could be done by freezing cuts from the plants or stocking the seeds. Plant genetic material in a 'gene bank' is preserved at -196° Celsius in Liquid Nitrogen as mature seed (dry) or tissue (meristems). The database of the largest gene banks in the world can be queried via a common website, Genesys. Gene banks exist to conserve genetic diversity Over 7.2 million plant germplasm accessions are housed in ~1,750 national and international gene banks. Gene banks are used to store and conserve the plant genetic resources of major crop plants and their crop wild relatives. There are many gene banks all over the world, with the Svalbard Global Seed Vault being probably the most famous one. Accession is the common term given to an individual sample in a gene bank, such as a distinct species or variety. Gene banks manage both genetic resources and information about those resources. National Gene Bank (NGB) Establishment: National Gene Bank was notified in 1996-97. Hosted By: National Bureau of Plant Genetic Resources (NBPGR), New Delhi. Purpose: To conserve the Plant Genetic Resources (PGR) for future generations in the form of seeds, genomic resources, pollen, etc. Functioning: NGB has four kinds of facilities Seed Genebank (- 18°C) Cryogenebank (-170°C to -196°C), In vitro Genebank (25°C), and Field Genebank, to cater to long-term as well as medium-term conservation. It stores different crop groups such as cereals, millets, medicinal and aromatic plants, narcotics, etc.
