TH090103

Here we present the novel 'taxon hypothesis' (TH) concept to accommodate fungal 'species hypothesis' (SH) into existing classification frameworks for taxonomic communication. As supplied with Digital Object Identifiers (DOIs), THs are flexible in time and enable direct cross-communication of higher level taxa along with evolving classification schemes. Every TH includes given number of SHs and consequently fixed number of fungal rDNA ITS sequences. DNA sequences generated by High-throughput or Sanger sequencing studies and identified against UNITE SHs will be automatically assigned to THs as well.

本研究提出了全新的分类单元假说（taxon hypothesis，TH）概念，旨在将真菌的物种假说（species hypothesis，SH）纳入现有的分类学交流框架。搭配数字对象标识符（Digital Object Identifier，DOI）使用时，分类单元假说具备时间灵活性，可实现高级分类单元的直接跨分类学交流，并适配持续演进的分类方案。每个分类单元假说均包含指定数量的物种假说，进而对应固定数量的真菌核糖体DNA（ribosomal DNA，rDNA）内转录间隔区（internal transcribed spacer，ITS）序列。通过高通量测序或桑格（Sanger）测序获得的、并与UNITE数据库中的物种假说进行比对鉴定的DNA序列，也将被自动归类至对应的分类单元假说之下。
