The concept of a universally recoverable segment of DNA that can be applied as an identification marker across species was initially applied to animals with the Cytochrome C Oxidase 1 or CO1 gene region. After several broad screenings of gene regions in the plant genome, three plastid (rbcL, matK, and trnH-psbA) and one nuclear (ITS) gene regions have become the standard barcode of choice in most investigations for plants.
The NMNH Plant DNA Barcode Project is exploring the development of new tools and applications for DNA barcoding. This website gives background and information on standard plant barcoding protocols used in these studies.
