Fungal Barcoding John W. Taylor University of California Berkeley, USA

Barcoding fungi is a great idea. The potential benefits for fungi are huge because most fungi are microscopic and we believe that most are unknown. Ecology and its applications would benefit tremendously. http://www.barcode.it/

Cytochrome Oxidase I is not the right gene for fungal barcoding. From the barcoding website: http://www.dnabarcoding.ca/primer/Primers.html PRIMERS Overview In order to obtain barcode sequences from such a broad spectrum of animal taxa, researchers require an arsenal of primer sets.

If Cytochrome Oxidase I requires an arsenal of primers, how can it work for any group of organisms?

Macrobes v. Microbes Macrobes: Phenotype is available in museums or herbaria, zoos or gardens, and nature. Taxa are well sampled. Microbes: Phenotype is available in herbaria and culture collections but NOT in nature. Taxa are poorly sampled.

Ward et al. (2005) amplified COI from more than 200 fish using different combinations of four newly designed primers: FishF1-50TCAACCAACCACAAAGACATTGGCAC30, FishF2-50TCGACTAATCATAAAGATATCGGCAC30, FishR1-50TAGACTTCTGGGTGGCCAAAGAATCA30, FishR2-50ACTTCAGGGTGACCGAAGAATCAGAA30. However, there was insufficient product from five species, necessitating the use of an additional forward primer: (50ATCTTTGGTGCATGAGCAGGAATAGT30) www.livescience.com

Seifert et al. (2007). We tested the performance of PenF1 with both PenR1 and AspR1 in PCR amplifications using genomic DNA isolated from ten species of the family Trichocomaceae, PCR amplications using PenF1 and PenR1 were sporadically successful, whereas amplications using AspR1 had a 100% success rate. Aspergillus and Penicillium subgenus Penicillium are closer relatives than either is to Penicillium subgenus Biverticillium. http://www.botany.utoronto. ca/ResearchLabs/MallochLa b/Malloch/Moulds
