内转录间隔区2(ITS2)是真核生物系统发育分析中公认的标记。参考序列及其二级结构的可靠资源是ITS2数据库(http://its2.bioapps.biozentrum.uniwuerzburg.de/).不过，该数据库最后一次更新是在2011年。在这里，我们提供了基本数据的重大更新，使实体数量几乎翻了一番。这增加了所有主要真核生物分支中所代表的分类群的数量。此外，对任职人数不足的群体增加了更多数据，并增加了一些新的群体。生命之树更广泛的覆盖面改善了系统发育分析和ITS2作为DNA条形码的能力。
The internal transcribed spacer 2 (ITS2) is a well-established marker for phylogenetic analyses in eukaryotes. A reliable resource for reference sequences and their secondary structures is the ITS2 database (http://its2.bioapps.biozentrum.uniwuerzburg.de/). However, the database was last updated in 2011. Here, we present a major update of the underlying data almost doubling the number of entities. This increases the number of taxa represented within all major eukaryotic clades. Moreover, additional data has been added to underrepresented groups and some new groups have been added. The broader coverage across the tree of life improves phylogenetic analyses and the capability of ITS2 as a DNA barcode.
