DNA barcode finds four new bird species

gist Paul Hebert, Ph.D., at the University of Guelph, the first author on the PLoS Biology paper, proposed that a short DNA sequence from a gene found in all animals can be used to identify species because in each species the sequence varies slightly. He coined the term DNA barcode for this idea, analogous to the supermarket barcodes that allow quick identification of millions of items.

The technique depends on analyzing a portion of a gene called cytochrome c oxidase I (COI) that is found in the power sources of cells of all animals. Most DNA is found in the nucleus of a cell. However, the mitochondria, the organelles within cells that are responsible for energy production, also contain DNA. Mitochondrial DNA (mtDNA) is known to accumulate mutations three to five times faster than DNA in the nucleus. As a result, the mtDNA of closely related species differs more than the nuclear DNA of those species and can be used to tell them apart.

In earlier studies, Hebert and colleagues at the University of Guelph showed that the COI gene was easy to isolate from a variety of animals, and that species in a broad range of animal life, from flatworms to vertebrates, have distinct COI sequences.

"The genetic barcoding technique developed by Paul Hebert and used in the PLoS Biology paper is the latest tool to be added to the taxonomist's toolkit, and it has enormous potential for broad impact," says David Schindel, Ph.D., executive director of the International Consortium for the Barcode of Life, based at the Smithsonian Institution in Washington, D.C. "The technique used to identify bird species by Hebert, Stoeckle and their colleagues could allow non-specialists to make these same species identifications using a relatively simple and inexpensive genetic test."
