Genamic barcoding is a relatively new concept. The system was developed to automate the identification of species with high precision and speed by using tag DNA sequences that are already widely used in biology. DNA barcoding may be useful for taxonomists and environmentalists. The initial goal of DNA barcoding is to create a database of all species' barcode sequences that can be accessed online. These databases will be used as a reference point against which DNA barcodes from recognised and unidentified samples may be compared. Because of this, it may be possible to solve several problems with conventional structural taxonomy, such as misinterpreting species because of phenotypic variation and genotypic fluctuation of the characters, failing to recognise cryptic taxa, and having trouble locating reliable characters because of lengthy maturation times (CBOL Plant Working Group, 2009). Locations where damage or a lack of development of morphological features makes it difficult to accurately identify species using just morphological qualities might benefit greatly from this method. DNA barcoding is a helpful tool since it provides information about undetected species, but it should not be mistaken for classification. Methods for selecting and redefining plant barcodes are discussed, and the authors share their thoughts on and recommendations for future research and practise.
