Dna fingerprinting for identification of plant species

Our characteristics, traits and physical features are determined by the specific arrangement of DNA base-pair sequences in the cell. It is this distinct arrangement of adenine, guanine, thymine and cytosine called DNA nucleotides that regulates the production of specific proteins and enzymes via the Central Dogma Theory [1]. In a living system, this DNA arrangement is uniform throughout the organism, irrespective of the organ.

The service makes DNA-based variety identification available to the public on a fee-for-service basis. The services are used by nursery managers, growers, processors, breeders and other industry representatives. Dried young leaves are the standard sample, but plant varieties can also be identified using other parts of the plant such as the fruit or dormant cuttings.

This allows samples to be tested in any season. Since, within a given crop, nearly all the DNA of one variety is identical to all other varieties, only small specific regions of the DNA are useful for the purpose of identification. The marker panel used is specific to each crop.

Sample collection materials and instructions are provided as part of the service. The service is available to both domestic and international clients.


Results are typically ready in three to four weeks. DNA-based Variety Identification This service determines or confirms the varietal identity of a particular tree or vine. Two separate samples of the plant are typed with a panel of DNA markers.DNA fingerprinting is used for the identification of genetic diversity within a breeding population.

It is used to identify a gene of interest. In the United States, it is also used to detect a .

Jan 03,  · Since the humble beginnings in , DNA fingerprinting has become an immensely important instrument for genotype identification in both wild plant species and their cultivated relatives. Application of RAPD for molecular characterization of plant species of medicinal value from an arid environment I.A. Arif, M.A. Bakir, H.A. Khan, A.H. Al Farhan, A.A. Al Homaidan, genetic fingerprinting of 11 plant species of desert origin (seven with the DNA from all the plant species. The amplified products of the RAPD. Wunsch A and Hormaza J Cultivar identification and genetic fingerprinting of temperate fruit tree species using DNA markers Euphytica ,, Mitchelson K and Morrica S. DNA finger printing methods for microbial pathogens: application to diagnostics, taxonomy and plant disease management.

DNA fingerprinting was invented in by Professor Sir Alec Jeffreys after he realised you could detect variations in human DNA, in the form of these minisatellites.

DNA fingerprinting is a technique that simultaneously detects lots of minisatellites in the genome to produce a pattern unique to an individual.

DNA fingerprinting of herbal drugs, though still in its early years, seems to be a promising tool for the authentication of medicinal plant species and for ensuring better quality herbs and nutraceuticals. DNA FINGERPRINTING AND CULTIVAR IDENTIFICATION K.V. Bhat National Research Centre on DNA Fingerprinting, N.B.P.G.R., New Delhi - identification.

DNA fingerprinting is a well-recognised and legally acceptable method of The same principles have been applied with considerable success in the identification of plants, .

Dna fingerprinting for identification of plant species

Abstract. Advances in knowledge about the molecular structure of plant genome and development of techniques to rapidly characterise genomic variations have established DNA fingerprinting as a powerful tool for identifying plant species, varieties, clones, individuals and even plant products.

DNA fingerprinting in plants is used for protection of the ecosystem, identification of marker traits, gene diversity and variation, and mutations.

Dna fingerprinting for identification of plant species

There are various methods for plant DNA fingerprinting like Restriction Fragment Length Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Amplified Fragment Length .
