Welcome to the Plant MITE Database

Miniature inverted-repeat transposable elements (MITEs) are prevalent in eukaryotic genomes, and are believed to be deletion derivatives of DNA transposons. MITEs usually have terminal inverted repeats (TIRs), flanked by short direct repeats (also called target site duplications, TSDs). MITEs are predicted to play important roles in gene and genome evolution. MITEs usually have a high copy number in plant genomes, and are often associated with genes. MITEs may be transcribed with genes and form pairs of natRNAs. MITEs generate a large number of small RNAs and may be the ancestors of some miRNAs genes. MITEs may regulate the expressions of nearby genes.

This MITE database contains more than 2 million MITE-related sequences of 3,527 MITE families, identified from 41 sequenced plant genomes. At least one sequence from each family has been manually investigated to verify that it is bona fide MITE and their TSD sequences are marked. You may search or download a sequence from the database. The database can be used to check if a sequence in question has MITE related sequences and to improve gene annotation since MITEs are frequently inserted into genes. The sequences in these databases can be also used to study the origin, amplification and evolution of MITEs.
