What's TXSearch?

TXSearch is a retrieval system for a Taxonomy Database which was unified by DDBJ, GenBank and EMBL , which is developed by DDBJ. This should be helpful as a reference of taxonomic names when you submit nucleotide sequences to DDBJ.

For construction of the nucleotide database, it is important to manage the organism names for the data and also necessary to unify the diverse names of the organisms. The taxonomy database is used as the reference database for searching the unified taxonomy names.
The primary purpose of the taxonomy database is unifying the organism names. Consequently, the taxonomy database is not an authoritative source for nomenclature or classification. Please refer to this link for description of the taxonomy database.
A taxonomic name may differ from the submitter's proposal or widely used taxonomic name because only the organism name in the taxonomy database which is managed by GenBank can be used for the entry.

How to use TXSearch

As shown in the figure below, please enter a taxonomic name and click the [Search] button. Then, TXSearch displays a list of taxonomic names which correspond to the word you entered. If you click one of the taxonomic names, TXSearch displays detailed information about the taxon. Furthermore, you can retrieve DDBJ entries for the taxon by clicking the [Get sequence(s) related to this taxon] button.

  1. Taxonomic name

    - You can enter 128 characters in this field.
    - If you would like to search the taxon that is exactly matched with your query term, please select [exact matching]. To search the taxon that is partially matched with your query, select [substring matching].
    If you would like to use ID number as query, please select [taxonomy id].
    - "*" is used as wild card. For example, if you enter "*coli" in this field, all taxonomic names that end by "coli" (E.coli and so on) will be retrieved.If you enter "*bear*", all taxonomic names that include "bear" will be displayed.
    - This field does not distinguish between upper and lower cases. For example, "*coli" and "*CoLI" will give exactly the same result.
    - If you would like to specify the species with only specific epithet, please add * before the specific epithet and select "exact matching".

  2. Class of taxonomic name

    Please select "scientific name" if the name you specified is the scientific name of the taxon. Please select "common name" if the name you specified is a common name. If you would not like to specify the class, please select "All" in the pop-up menu.

  3. Taxonomic rank

    Please specify the rank of the taxonomic name. If you would not like to specify the rank, please select "All" in the pop-up menu.


"Version" and "Updated"

"Version" is system version. "Updated" is the date of system or screen display (including notice) renewal.
