BFR2: a curated benthic foraminifera ribosomal reference database

The current BFR2 database has been expanded with 2,699 additional sequences, including undescribed taxonomic sequences for benthic foraminifera. To support different applications, the database is distributed in FASTA, tab-separated text (TSV), and Microsoft Excel formats and is available as two complementary datasets: Complete dataset (8,023 sequences): includes all available sequences, encompassing both described and undescribed taxonomic sequences. Curated taxonomic dataset (7,111 sequences): includes only sequences with curated taxonomic name at the genus and/or species level. The tab-separated text files and Excel file include the following fields: BFR2 number = unique internal sequence accession number; length = sequence length; class = class to which each sequence is assigned; order/suborder/clade = order/suborder/clade to which each sequence is assigned; family = family to which each sequence is assigned; genus = genus to which each sequence is assigned; species = species to which each sequence is assigned; isolate number = unique DNA extraction number; clone/direct: indicates whether it has been directly sequenced or cloned; genbank_accession = NCBI sequence accession number; sampling site = biogeographic region where the specimen has been collected; latitude in decimal degrees, longitude in decimal degrees; collection date = year in which specimen was collected; collector = person who collected the specimen; publication_submission = publication associated to the sequence or person who submmited the sequence; journal = journal associated to publication; first author = first author associated to publication/sequence; taxonomic remarks = additional taxonomic information/comment; sampling remarks = addional sampling information/comment.
