SH1039107.10FU

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为基于DNA的物种假说（DNA-based Species Hypotheses, SH）的界定、识别、交流及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。所有物种假说均被赋予DOI形式的唯一、稳定名称，其分类学和生态学注释通过分布式、基于网络的第三方注释工作进行验证。通过考虑SH中所有序列的鉴定结果，SH尽可能与分类单元名称及其分类等级（门（phylum）、纲（class）、目（order）等）关联。每个SH均选择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序列数量的增长，该系统及数据会自动更新。
