The Smithsonian PIs are seeking collaborations with local plot PIs to initiate barcoding activities worldwide. The main goals are to provide genetic identifiers for each species, test species boundaries, assist in identifying new species, provide a tool for ecological forensic applications, and generate testable phylogenetic hypotheses for the tree communities. The project will eventually generate DNA barcodes for the over 8,500 species of trees recorded from the plots. The Smithsonian National Museum of Natural History Department of Botany Plant DNA Barcode Group is collaborating with the Center for Tropical Forest Science/Smithsonian Institution Global Earth Observatory on an initiative to generate DNA barcodes for the trees found in their forest dynamics plots. DNA barcoding has become a vital new tool for taxonomists who are charged with the inventory and management of the Earth's immense and changing biodiversity.
Sanger sequencing of organism specific, defined DNA barcode regions is still. It also has the potential to speed the discovery of the thousands of species yet to be named. Eurofins offers different DNA barcoding services for species identification. By harnessing advances in molecular genetics, sequencing technology, and bioinformatics, DNA barcoding is allowing users to quickly and accurately recognize known species and retrieve information about them. DNA barcode consists of a standardized short sequence of DNA between 400 and 800 base pairs long that in theory can be easily isolated and characterized for all species on the planet. This problem was a major reason for the development of a new method for the quick identification of any species based on extracting a DNA sequence from a tiny tissue sample of any organism. A taxonomic impediment for many systematists, field ecologists, and evolutionary biologists is determining the correct identification of a plant or animal sample in a rapid, repeatable, and reliable fashion.
