OTU(operational taxonomic units),即操作分类单元。通过一定的距离度量方法计算两两不同序列之间的距离度量或相似性,继而设置特定的分类阈值,获得同一阈值下的距离矩阵,进行聚类操作,形成不同的分类单元。专业解释太书面不好理解?没事儿,给你举个“栗子”就明白了! 2、OTU在16S测序中有何用? 高通量测序得到的16S序...
Operational Taxonomic Unit (OTU): a group of closely related individuals which are arranged together based on the similarity of specific sequences (usually the 16S rRNA gene). From:Computational and Structural Biotechnology Journal,2021 Also in subject area: ...
There is a growing group of scientists who prefer the use of operational taxonomic unit (OTU) to name their units of comparison.doi:10.1128/9781555815509.ch7Ramon Rosselló-MoraArantxa López-LópezRossello-Mora, R., and Lopez-Lopez, A. (2008) The last common denominator: species or ...

is posing important computational challenges, requiring specialized bioinformatics solutions at different stages during the processing pipeline, such as assembly of paired-end reads, chimera removal, correction of sequencing errors, and clustering of those sequences into Operational Taxonomic Units (OTUs). ...
The obtained DNA sequences were quality trimmed and assigned to operational taxonomic units (OTUs) at a 97% similarity cutoff. Then the representative sequence of the OTU was further aligned to the SILVA/v132 (https://www.arb-silva.de/) to obtain the taxonomic annotation information. The ...
Strains of the same bacterial species (ideally belonging to the same OTU) typically only share some genes (the core genome), while other genes are strain-specific and unique. It is thus unclear to what extent are important functional traits homogeneous within an OTU and how correctly can ...
More recently three cryptic Operational Taxonomic Units (OTUx, y and z) have been described in populations ofEimeriarecovered from chickens in Australia. Two of the three OTUs have also been detected in sub-Saharan Africa, but their occurrence, pathology and the risk they pose is largely ...
