A DNA barcode for land plants
Richardson, James-Edward; Erickson, David L.; Burgess, Kevin; Long, David G.DNA barcoding involves sequencing a standard region of DNA as a tool for species identification. However, there has been no agreement on which region(s) should be used for barcoding land plants. To provide a community ...Artículo. 2009
