TREP, the TRansposable Elements Platform

TEs by Classes

TREP implements the TE classification system proposed by Wicker et al., 2007. The naming convention proposes that superfamily names are written in italic and at least the first letter is capitalized.

Click on the "Code" link for background information on individual TE superfamilies.

Hover over "DNA" and "protein" links (e.g. 'total_TREP', 'nrTREP' or 'PTREP') for information about number of TEs in database and click the corresponding links for download of TE sequences in FASTA format.
