“…MITEs were originally discovered in plants and soon identified in many different organisms including fungi (Yeadon and Catcheside 1995), insects (Braquart et al 1999;Tu 2000), nematodes (Surzycki and Belknap 2000), fishes (Izsvak et al 1999) and humans (Smit and Riggs 1996). MITE elements are typically small in size (\600 bp), A/T-rich and have the potentiality to form single stranded secondary structures.…”

Miniature inverted-repeat transposable elements (MITEs) are short, non autonomous DNA elements that are widespread and abundant in plant genomes. The high sequence and size conservation observed in many MITE families suggest that they have spread recently throughout their respective host genomes. Here we present a maize genome wide analysis of three Tourist-like MITE families, mPIF, and two previously uncharacterized families, ZmV1 and Zead8. We undertook a bioinformatic analysis of MITE insertion sites, developed methyl-sensitive transposon display (M-STD) assays to estimate the associated level of CpG methylation at MITE flanking regions, and conducted a population genetics approach to investigate MITE patterns of expansion. Our results reveal that the three MITE families insert into genomic regions that present specific molecular features: they are preferentially AT rich, present low level of cytosine methylation as compared to the LTR retrotransposon Grande, and target site duplications are flanked by large and conserved palindromic sequences. Moreover, the analysis of MITE distances from predicted genes shows that 73% of 263 copies are inserted at less than 5 kb from the nearest predicted gene, and copies from Zead8 family are significantly more abundant upstream of genes. By employing a population genetic approach we identified contrasting patterns of expansion among the three MITE families. All elements seem to have inserted roughly 1 million years ago but ZmV1 and Zead8 families present evidences for activity of several master copies within the last 0.4 Mya.

“…The heavy smearing observered in the Southern blots would indicate that the elements Mild-1 and Mild-3 are present in high copy numbers in these two congeneric species. Southern results of MITEs in other species varies from distinct bands to smears as seen in L. decemlineata and L. juncta (Bureau & Wessler, 1992;Braquart et al, 1999;Yang et al, 2001;Menzel et al, 2006;Remigereau et al, 2006).…”

MITEs (Miniature inverted-repeat transposable elements) are reminiscence of non-autonomous DNA (class II) elements, which are distinguished from other transposable elements by their small size, short terminal inverted repeats (TIRs), high copy numbers, genic preference, and DNA sequence identity among family members. Although MITEs were first discovered in plants and still actively reshaping genomes, they have been isolated from a wide range of eukaryotic organisms. MITEs can be divided into Tourist-like, Stowaway-like, and pogo-like groups, according to similarities of their TIRs and TSDs (target site duplications). In despite of several models to explain the origin and amplification of MITEs, their mechanisms of transposition and accumulation in eukaryotic genomes remain poorly understood owing to insufficient experimental data. The unique properties of MITEs have been exploited as useful genetic tools for plant genome analysis. Utilization of MITEs as effective and informative genomic markers and potential application of MITEs in plants systematic, phylogenetic, and genetic studies are discussed.
