DNA Barcoding of Pacific Invasive and Pest SpeciesPacific Science Congress Kuala Lumpur David E. Schindel, Executive Secretary National Museum of Natural History Smithsonian Institution SchindelD@si.edu; http://www.barcoding.si.edu 202/633-0812; fax 202/633-2938
Today’s Goals • Share information on barcoding, invasives • Share information on projects and organizations in Pacific • Discuss potential regional cooperation; and • Discuss possible formation of a PSA Working Group on DNA barcoding of invasive/pest species: • Participants (individuals, labs, institutes, agencies) • Activities (training, workshops, collecting, producing data) • Deliverables (data, publications, websites)
Existing Activities • National quarantine agencies (NPPOs) • Regional agencies and initiatives (RPPOs, Quads, QBOL) • Global Initiatives (IPPC, CABI, GISP) • BioNET INTERNATIONAL LOOP PaciNET • PBIF: Pacific Node of GBIF
The DNA Barcoding Initiative • Barcoding is becoming a global standard for species identification • Rapidly expanding by region, taxa, applications • The Barcoding Initiative is global with participants in 50+ countries • CBD, IPPC, Global Taxonomy Initiative, Census of Marine Life, others involved • Government agencies: USDA, FDA, NOAA
Species Identification Matters • Basic research on evolution, ecology • Invasive species (e.g., in ballast water) • Agricultural pests/beneficial species • Endangered/protected species • Disease vectors/pathogens • Environmental quality indicators • Managing for sustainable harvesting • Consumer protection, ensuring food quality • Fidelity of seedbanks, culture collections
A DNA barcode is a short gene sequence taken from standardized portions of the genome, used to identify species

Non-COI regions for other taxa • Land plants: • Chloroplast matK and rbcL approved Nov 09 • 70-75% resolvingability, higher in angiosperms • Non-coding plastid and nuclear regions being explored • Fungi: • CBOL Working Group met this week in Amsterdam • Agreed to recommend ITS; 72% effective • Protists: • CBOL Working Group July meeting, Berlin
How Barcoding Works • PHASE 1: Build a barcode reference library: • Well-identified specimen • Tissue subsample • DNA extraction, PCR amplification • DNA sequencing • Data submission to GenBank • PHASE 2: Identify unknowns: • Any unidentified juvenile, adult, fragment, product • Tissue sample, DNA, sequencing • Comparison with sequences in reference library
Current Norm: High throughput Large labs, hundreds of samples per day Large capacity PCR and sequencing reactions ABI 3100 capillary automated sequencer
● US$100-150K purchase ● 2-3 hours processing time ● 150-500 samples per day ● US$3-5 per sample
Technology Development Partnership Goal The DNA Sequencing Lab of 2013?

Producing Barcode Data: 201?Barcode data anywhere, instantly • Data in seconds to minutes • Pennies per sample • Link to reference database • A taxonomic GPS • Usable by non-specialists
Barcode of Life Community 1,264,000 specimens already barcoded from 104,500 species Networks, Projects, Organizations • Promote barcoding as a global standard • Build participation • Working Groups • BARCODE standard • International Conferences • Increase production of public BARCODE records
The International Barcode of Life Project (iBOL) 5 Million specimens, 500,000 species in 5 years $150 million with core funding from Genome Canada iBOL website, University of Guelph, Ontario: www.ibol.org
iBOL Theme 1: DNA Barcode Library WG 1.1 Vertebrates WG 1.2 Land Plants WG 1.3 Fungi WG 1.4 Human Pathogens and Zoonoses WG 1.5 Agricultural and Forestry Pest and Parasitoids WG 1.6 Pollinators WG 1.7 Freshwater Bio-Surveillance WG 1.8 Marine Bio-Surveillance WG 1.9 Terrestrial Bio-Surveillance WG 1.10 Polar Life
Consortium for the Barcode of Life (CBOL)CBOL Member Organizations: 2010 • 200+ Member organizations, 50 countries • 35+ Member organizations from 20+ developing countries
Outreach Activities • Cape Town, South Africa, April 2006, SANBI • Scale insects in African agriculture • Nairobi, Kenya, October 2006 • Commercial fisheries in Rift Valley lakes • Brazil, March 2007 • Hardwood tree species • Endangered mammals, reptiles, amphibians • Taiwan, September 2007 • Nigeria, October 2008 • Beijing, May 2009 • India, November 2010
Adoption by Regulators • International Plant Protection Commission • CBOL and APHIS to host Diagnostic Protocol Panel meeting, July 2010 • Federal Aviation Administration – $500K for birds • Environmental Protection Agency • $250K pilot test, water quality bioassessment • Food and Drug Administration • Reference barcodes for commercial fish • NOAA/NMFS • $100K for Gulf of Maine pilot project • CITES, National Agencies, Conservation NGOs
Conclusions • Barcoding is a cost-effective system for rapid identification • Barcode reference libraries are being constructed for several endangered groups • CBOL and iBOL provide a global network of specialists capable of constructing barcode reference libraries on selected groups • Partnerships with national and regional groups and regulatory agencies are the critical missing components
