Operational taxonomic unit : ウィキペディア英語版 | Operational taxonomic unit In phylogeny an operational taxonomic unit (OTU) is an operational definition of a species or group of species often used when only DNA sequence data is available. It is the most commonly used microbial diversity unit. The definition given by NCBI is: "Taxonomic level of sampling selected by the user to be used in a study, such as individuals, populations, species, genera, or bacterial strains." Another definition: "Operational taxonomic unit, species distinction in microbiology. Typically using rRNA and a percent similarity threshold for classifying microbes within the same, or different, OTUs" The number of OTUs defined may be inflated due to errors in DNA sequencing. ==See also==
