What is the name of the genetic sequence used to identify a plant?

Explanation

t. DNA barcoding is a taxonomic method that uses a very short genetic sequence from a standard part of a genome.
2. The genetic sequence used to identify a plant is known as "DNA tags" or "DNA barcodes".
3. Paul Hebert in 2003 proposed .DNA barcoding. and he is considered as .Father of barcoding..
4. The gene region that is being used as an effective barcode in plants is present in two genes of the chloroplast, matK and rbcL, and have been approved as the barcode regions for plants.
5. Sequence of unknown species can be matched from submitted sequence in GenBank using Blast (web - programme for searching the closely related sequence).
Significance of DNA barcoding:
1. DNA barcoding greatly helps in identification and classification of organism.
2. It aids in mapping the extent of biodiversity.
3. DNA barcoding techniques require a large database of sequences for comparison and prior knowledge of the barcoding region.
4. However, DNA barcoding is a helpful tool to determine the authenticity of botanical material in whole, cut or powdered form.
