  • Reference/representative sequences

    Following Kõljalg et al. (2013), each terminal fungal taxon for which two or more ITS sequences are available is referred to as a species hypothesis (SH). One sequence is chosen to represent each SH; these sequences are called representative sequences (RepS) when chosen automatically by the computer and reference sequences (RefS) when those choices are overridden (or confirmed) by users with expert knowledge of the taxon at hand.

    There are five releases of the RepS/RefS set: special files pre-formatted for QIIME, mothur, USEARCH, and CREST use, and one general FASTA release for, e.g., local BLAST searches. Pre-formatted datasets can also be used for other pipelines supporting these formats, e.g. SCATA and LotuS.

    There is a brand new release of UNITE/INSDC representative/reference sequences for use in reference-based chimera detection of fungal ITS sequences in UCHIME and similar programs.

  • QIIME release

    QIIME release (download)
    Three sets of QIIME files are released, corresponding to the SHs resulting from clustering at the 3% distance (97% similarity) and 1% distance (99% similarity) threshold levels. The third set of files is the result of a dynamic use of clustering thresholds, such that some SHs are delimited at the 3% distance level, some at the 2.5% distance level, some at the 2% distance level, and so on; these choices were made manually by experts of those particular lineages of fungi. The syntax is the same throughout the three sets of files.

    Each SH is given a stable name of the accession number type, here shown in the FASTA file of the dynamic set:

    >SH099456.05FU_FJ357315_refs
CACAATATGAAGGCGGGCTGGCACTCCTTGAGAGGACCGGC…

SH099456 = accession number of the SH
05FU = global key release 5, organism group FUngi
FJ357315 = GenBank/UNITE accession number of sequence chosen to represent the SH
refs = this is a manually designated RefS
(reps = this is an automatically chosen RepS)

    In the corresponding text file, the classification string of the SH is found:

    SH099456.05FU_FJ357315_refs    k__Fungi;p__Ascomycota;c__Dothideomycetes;o__Pleosporales;f__Pleosporaceae;g__Embellisia;s__Embellisia_planifunda

    This specifies the hierarchical classification of the sequence. k = kingdom; p = phylum ; c = class ; o = order ; f = family ; g = genus ; and s = species. Missing information is indicated as "unidentified" item; “f__unidentified;” means that no family name for the sequence exists.

    UNITE follows the Index Fungorum classification in nearly all regards.

  • Top50 release
    Top50 release (download)

    This is a FASTA release of the sequences of the "Top 50 most wanted fungi" paper. One representative sequence from each SH (singletons as well as non-singletons) is provided. Approximately 1,000 compound clusters are unidentified at each of the phylum, class, and order levels, such that this file contains significantly more than 50 sequences. Use this file if you want to find out if any of your newly recovered OTUs belong among the “most wanted” fungi. All these SHs are also present in our other release files; this is the release where you find only these "most wanted" SHs.

    Format (example): 

    >Fungi|HM123225|SH221352.07FU|refs|k__Fungi;p__unidentified;c__unidentified;o__unidentified;f__unidentified;g__unidentified;s__Fungi_sp|UCL7_006587
TTGGTTGGATATATTATAGCCTCTTG...

HM123225 = GenBank/UNITE accession number of representative sequence
SH221352.07FU = species hypothesis accession number
UCL7_006587 = compound cluster accession number
refs = this is a manually designated RefS
(reps = this is an automatically chosen RepS)

    If you can improve the taxonomic annotation of any of the "most wanted" lineages, then please do so! Either by third-party annotation in UNITE or by writing one of the UNITE developers.

  • General FASTA release

    General FASTA release (download)
    This release consists of a single FASTA file: the RepS/RefS of all SHs, adopting the dynamically use of clustering thresholds whenever available. The format of the FASTA header is:

    >Glomeraceae|AM076560|SH146432.05FU|refs|k__Fungi;p__Glomeromycota;c__Glomeromycetes;o__Glomerales;f__Glomeraceae;g__;s__uncultured_Glomus

    This is the file we recommend for local BLAST searches against the SHs.

  • UCHIME/USEARCH/UTAX/SINTAX reference datasets
    UCHIME reference dataset

    This is a release of UNITE/INSDC representative/reference sequences for use in reference-based chimera detection of fungal ITS sequences in UCHIME and similar programs. It consists of several datasets:

    1. The file "*original*" is meant for chimera detection of more or less full-length ITS sequences and is designed to suit the needs of the average user and the kind of ITS datasets typically used in fungal systematics. The sequences were trimmed to remove any larger chunks of SSU/LSU as applicable.
    2. The folder "untrimmed_ITS_sequences" contains a FASTA file with untrimmed ITS sequences. This file can be used to tailor chimera reference datasets to suit particular needs, such as including only truly full-length ITS sequences or including 25 base-pairs of the SSU/LSU in the sequences. The ITSx options "--partial" and "--anchor" switches can be used to accomplish this.
    3. The folder "ITS1_ITS2_datasets" contains ITS1-only and ITS2-only versions of the reference dataset; these files are recommended over the "*original*" file for chimera detection in amplicon-based ITS1 or ITS2 datasets.

    Reference: Nilsson et al. 2015. A comprehensive, automatically updated fungal ITS sequence dataset for reference-based chimera control in environmental sequencing efforts. Microbes and Environments (paper).

    USEARCH/UTAX/SINTAX release (download)

    Reference file for USEARCH/UTAX/SINTAX. For optimized parameters and further information, please refer to the UTAX UNITE page. This is the "dynamic" release of the UNITE species hypotheses system, with singleton species hypotheses included. Any parts of the 18S and 28S are left in these sequences. This reference file can be used for ITS1-only or ITS2-only sequences if parameters trained on ITS1 or 2 only ('taxconfs' files) are used. ITS regions can be extracted using the ITSx tool.

UNITE Classification

NB! From Version 7.0 onward UNITE follows fungal classification published in Fungal Diversity, May 2018 (https://link.springer.com/article/10.1007/s13225-018-0401-0).

Future UNITE versions will have alternative classifications connected to the SH datasets and user can choose one or many to be used in analyses.
