Dr. Spouge was invited to the 2009 Edinburgh Conference "Selecting Barcode Loci for Plants", a gathering of a subset of the Plant Working Group within the Consortium for the Barcode of Life, to help select a plant barcode. The other conference participants sequenced 7 candidate barcode loci across a broad range of land plants, so Dr Spouge and Damon Little of the New York Botanical Garden could analyze the resulting data, to permit the conference participants to select markers for a plant barcode. The Edinburgh Conference selected rbcL and matK as the 2 plant barcode markers, from 7 choices. Dr. Spouge performed a similar data analysis for the Fungal Barcode Working Group in Amsterdam (2011), which selected ITS (the Internal Transcribed Spacer between structural ribosomal RNAs) from 4 choices. He offered similar services to the Protist Barcode Working Group in Berlin (2011), but insufficient data prevented a decisive analysis. He had made implementations of his analysis publicly available in user-friendly programs, to permit barcode researchers to carry out their own analyses. In collaboration with Dr. Martn, he has analyzed the efficacy of barcodes in identifying South-East Asian fungi. Such analyses are likely to be particularly important in selecting secondary markers in different fungal clades.
