File references.bryo-ch.fasta This file contains the sequences produced in silico (EcoPCR, Ficetola et al. 2010 BMC Genomics, Vol 11:434) by the trnL c/h primers (Taberlet et al. 2007 Nucleic Acids Research, Vol. 35, No. 3 e14). The original sequences have been produced by sanger sequencing with the trnL c/d primers. Data collection: Hans K. Stenøien, Kristian Hassel selection of target species. Kristian Hassel checked identification/identified the specimens. Kristian Hassel, Galina Gussarova collected tissue for DNA extraction in the herbarium. Audun Schrøder-Nielsen, Eva Bellemain, Galina Gussarova extracted DNA. Audun Schrøder-Nielsen Eva Bellemain, Galina Gussarova amplified DNA. Audun Schrøder-Nielsen Eva Bellemain, Galina Gussarova, Laura Epp sequenced DNA and checked the sequences. The project was designed and led by Christian Brochmann, Eva Bellemain and Galina Gussarova Contact author: Christian Brochmann (christian.brochmann@nhm.uio.no) The header of each sequence contains: (i) the ID for the sequence (ii) the scientific name of the correponding taxon (scientific_name) (iii) the taxonomic rank of ncbi taxid (taxonomic_rank) (iv) the ncbi taxon identifier (taxid)
