P-MITE: a database for plant miniature inverted-repeat transposable elements. Nucleic Acids Res. 2013;42(Database issue):D1176–81

Miniature inverted-repeat transposable elements (MITEs) are prevalent in eukaryotic species including plants. MITE families vary dramatically and usually cannot be identified based on homology. In this study, we de novo identified MITEs from 41 plant species, using computer programs MITE Digger, MITE-Hunter and/or Repetitive Sequence with Precise Boundaries (RSPB). MITEs were found in all, but one (Cyanidioschyzon merolae), species. Combined with the MITEs identified previously from the rice genome,>2.3 million sequences from 3527 MITE families were obtained from 41 plant species. In general, higher plants contain more MITEs than lower plants, with a few exceptions such as papaya, with only 538 elements. The largest number of MITEs is found in apple, with 237 302 MITE sequences. The number of MITE sequences in a genome is significantly correlated with genome size.
