UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.

UNITE为基于DNA的物种假说（Species Hypotheses，SH）的界定、识别、交流与应用提供了统一框架。国际核苷酸序列数据库中的所有真菌ITS序列通过应用一组动态距离值（<0.5–3.0%）聚类至近似物种水平。每个物种假说被赋予DOI格式的唯一且稳定名称，其分类学与生态学注释通过分布式、基于网络的第三方注释工作验证。SH会尽可能关联分类单元名称及其分类层级（门、纲、目等），具体方式为整合该SH内所有序列的鉴定结果。每个SH均选取一条自动或手动指定的序列作为代表。这些序列已发布（https://unite.ut.ee/repository.php），供科学界使用，例如用于本地序列相似性搜索和下一代测序分析流程。随着公共真菌ITS序列数量的增长，该系统与数据将自动更新。
