文摘内容
MITEs (Miniature inverted-repeat transposable elements) are reminiscence of nonautonomous 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 mechanlsms 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。
