DNA Barcoding of Medicinal Plants

摘要: DNA barcoding is a useful technique for diversity analysis whereby standardized region of used the identification species or taxonomic group organisms. These standard regions are called barcode. small sequences entire genome. In plants, has application in phylogenetic analysis, authentication, inter- and intraspecific diversity, classification into wild cultivated genotypes, study phylogeographical patterns, detection adulteration. The barcode loci, i.e., able to discriminate closely related identify new cryptic as well. Depending on taxon complexity species, different loci purpose. animals, universal barcode, mitochondrial cytochrome c oxidase I (COI) gene discrimination. However, this cannot be plants due its limited divergence. Thus, use only some algae. Efforts going find suitable plants. Since last decades, matK, rbcL, trnH-psbA, ITS, trnL-F, 5S-rRNA, 18S-rRNA candidate being barcodes article provides an overview these through approaches which have gained importance challenges development multilocus tiered along with frontier areas been analyzed detail.
