4. Overview – The politics of DNA barcoding. – What happened to cox1 ? – Should ITS be the official Fungal Barcode? – Data standards for the barcode keyword. – Data resources for DNA barcoding. – International barcoding projects Our goal: Motivate mycological participation in DNA barcoding! – Formalize the fungal barcode. – Establish Fungal Working Group – Develop new fungal barcoding projects. – Participate in multi-kingdom projects. “DNA, you know, is Midas’ gold. Everybody who touches it goes mad.” Maurice Wilkins, quoted in The Eighth Day of Creation

6. Consortium for the Barcode of Life (CBOL) Regulates the ‘barcode’ keyword for GenBank Organization –Secretariat Smithsonian Institution, Washington, D.C., USA 5 people –Executive Committee 7 members, including Pedro Crous –Implementation Board 19 members, including Conrad Schoch –Members 200 Member Organizations, 50 countries Natural history museums, biodiversity organizations Users: e.g., government agencies Private sector biotech companies, database providers Facilitates barcoding but does not fund research www.barcodeoflife.org

7. The Barcode Keyword in GenBank The Barcode Data Standard Sequence records with… –Voucher specimens –On-line metadata –Reliable standard of taxonomic identification –Agreed gene region sanctioned by peer review by CBOL Implementation Board –Sequence traces Identification of unknowns of ALL kingdoms (except bacteria) –GenBank –Barcode of Life Database (BOLD)

8. What is DNA Barcoding? Part 2. (or two or three genes?) All Kingdoms, All Species, One gene (or two or three genes?) The purpose is identification … NOT phylogeny In animals, the barcode gene is cytochrome oxidase 1 ( cox1 or CO1) A single copy mitochondrial gene, AT rich 648 bp region is the core for animals In plants, the barcode genes are matK and rbcL – Hollingsworth et al., 2009, PNAS 106: 12794–12797, 2009. In fungi, the barcode gene has not been formalized – By default it is cox1 until an alternative is accepted Barcode

9. Big science – More than $100,000,000 Biodiversity Institute of Ontario (Guelph) Netherlands Centre for Biodiversity Naturalis (Leiden) – € 30 million High throughput sequencing – Near genome centre volumes – Immediate data release policy (based on public genome model) is controversial – Primer mixes often used for PCR – M13 tagged sequencing primers – Data release papers What is DNA Barcoding? Part 3.

10. Taxon specific ‘campaigns’ Development of multikingdom databases –For use by all scientists and the public… not just mycologists Multi-kingdom projects –QBOL – Quarantine Barcode of Life Ecological projects –IM-Bol Indoor Mycota Barcode of Life Geographic Projects –Moorea What is DNA Barcoding?

11. Barcode of Life Database – BOLD www.boldsystems.org Mirrored in China, negotiations with ECBol, Australia, Mexico Accepts ITS sequences as barcodes Submission open to anyone Few fungal sequences Spreadsheets for metadata No specific fungal format Process can be tedious Images of specimens Descriptions ‘Automated’ GenBank submission

12. Barcode Submission Tool www.ncbi.nlm.nih.gov/WebSub/index.cgi?tool=barcode Familiar submission process Trace archive available www.ncbi.nlm.nih.gov/Traces/home/ ITS sequences not yet accepted as barcodes Submission open to anyone Few fungal barcode sequences are now cox1 Metadata must be stored off-site

13. RefSeq Targeted Loci Bacteria: all type sequences Fungi: 200 sequences from AFToL, 28S, 18S, just beginning INSD (International Nucleotide Sequence Databases) DDBJ EMBL GenBank submission selection & some curation (NCBI) RefSeq model organisms reference organisms genomic level 16S rRNA* other molecular markers other RNAs www.ncbi.nlm.nih.gov/RefSeq/ GenBankRefSeq Not curatedCurated Author submitsNCBI creates from existing data Only author can reviseNCBI revises as new data emerge Multiple records for same loci commonSingle records for each molecule of major organisms Records can contradict each other Data exchanged among INSDC membersExclusive NCBI database Akin to primary literatureAkin to review articles

15. Criticisms of DNA Barcoding Not science (or bad science) A threat to classical taxonomy Removes funding from classical taxonomy Standardization of markers impossible Standardization of markers impossible Oversimplifies delimiting species Oversimplifies delimiting species It is not phylogeny Distrust and questioning of CBOL’s mandate National pride National pride Disciplinary pride Disciplinary pride

18. ECBOL- European Consortium for the Barcode of Life Mission: To unleash the potential of European expertise and collections to contribute towards identifying life on earth. Plan: Establish a Network of European Leading Laboratories (NELL) Formalise National DNA barcoding campaigns in each European country Establish new projects and barcoding campaigns, Functioning as the European node for international initiatives such as iBOL Participating countries: Belgium, Finland, France, Germany, Italy, Lithuania, Netherlands, Norway, Poland, Portugal, Spain, Switzerland, U.K. www.ecbol.org ECBOL2 meeting June 2010, Braga, Portugal Lorenzo Lombard l.lombard@cbs.knaw.nl

19. Selecting barcode genes International Nucleotide Sequence Database Collaboration – INSDC, GenBank, the European Molecular Biology Laboratory and the DNA Data Bank of Japan – CBOL Implementation Board decides by peer review which gene regions receive BARCODE status Possible reasons for rejection of cox1 – PCR problems (amplification or primer problems) – Patterns of inter- and infraspecific variation – Resolving power Selection of new genes – Patterns of inter- and infraspecific variation – Prefer a ‘barcode’ gap – Universality of primer pair etc.

23. The ITS reality… Hurray! Large reference database –most not barcode data standard compliant Robust primers Strong demand from many mycologists that this be the fungal barcode –Especially ecologists studying environmental metagenomics

24. The ITS Reality – BOO! Multiple copies within species –At this conference… –Dan Lindner – Laetiporus, this conference –Uwe Simon & M. Weiss – Ascomycetes –Of concern for cloning based and metagenomic studies wanting to use barcode ID databases Serious lack of resolution in Ascomycetes –Possibly too short –500-700 bp optimum barcode but subtract 150 bp 5.8S… Chimera problems for some methodological approaches

Establish Working Plan Prepare Fungal Barcoding proposal For peer reviewed publication For CBOL implementation board approval CBOL will support meetings of WG as necessary

27.

28. Fungal DNA Barcoding – Proposed Proposal General Barcode for Fungi – rDNA internal transcribed spacer (ITS) Secondary barcodes – Yeasts rDNA large subunit (28S, LSU) D2 region – Ascomycetes Second barcode required, subsequent proposal Oomycetes – A separate proposal – Data on ITS, cox1 and LSU now being prepared for publication – 2 barcode system rDNA internal transcribed space (ITS) rDNA large subunit (28S, LSU) D2 region Other groups?
