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为界定、识别、交流以及处理基于DNA的物种假说（Species Hypotheses，下文简称SH）提供了统一的解决方案。国际核苷酸序列数据库中的全部真菌内部转录间隔区（Internal Transcribed Spacer，下文简称ITS）序列，均通过应用0.5%至3.0%区间的动态距离阈值，被聚类至近似物种层级。所有SH均会被赋予唯一且稳定的数字对象标识符（Digital Object Identifier，DOI）格式的专属名称，其分类学与生态学注释信息将通过分布式网页第三方注释流程完成核验。所有SH会结合其包含的全部序列的鉴定结果，与尽可能匹配的类群名称及其分类层级（如门、纲、目等）建立关联。研究人员会为每个SH选取一条经自动或人工指定的序列作为该SH的代表序列。上述代表序列已发布于https://unite.ut.ee/repository.php，可供科学界用于本地序列相似性检索、新一代测序分析流程等科研场景。随着公共真菌ITS序列的数量持续增长，该系统及其数据集将自动完成更新。
