Abstract
DNA barcoding provides a rapid, accurate, and standardized method for species level identification using short DNA sequences. Such a standardized identification method is useful for mapping all the species on Earth as DNA sequencing technology has become cheaper now. Using this technique, it is possible to map the Earth’s immense biodiversity resources, and entries can enrich the databases (DB). Hence, in this review all the available DNA barcode databases have been reviewed for its promises and limitations. The important DNA barcode databases are International Nucleotide Sequence Database Collaboration (INSDC), Barcode of Life Database (BOLD), BioBarcode, Medicinal Materials DNA Barcode Database (MMDBD), Herbarium of Med Plants of India, and PLANTS Database. All these DBs possess a vast number of specimen entries and also help in understanding their genetic relationships and evolution. Some databases also contain a chromatogram viewer, which helps the DNA sequence analysis. These barcode database servers provide bioinformatics tools as one stop solution. It promotes the rapid acquisition of biological species and to reach global standards in the aspects of standardization, depository, management, and analysis.
