SH1044831.10FU

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、交流和处理基于DNA的物种假设（Species Hypotheses, SH）提供了统一方法。国际核苷酸序列数据库中的所有真菌ITS（Internal Transcribed Spacer）序列通过应用一组动态距离值（<0.5–3.0%）被聚类至近似物种水平。每个物种假设均被赋予一个唯一且稳定的DOI格式名称，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得到验证。物种假设会尽可能关联到分类单元名称及其分类等级（门、纲、目等），这一过程综合考虑了该物种假设中所有序列的鉴定结果。每个物种假设均会选定一条自动或手动指定的序列作为代表，这些序列已在https://unite.ut.ee/repository.php发布，供科学界用于本地序列相似性搜索、下一代测序分析流程等场景。随着公共真菌ITS序列数量的增加，该系统与数据会自动更新。
