| Abstract |
To investigate the recent transposition activity of T2 family miniature inverted-repeat transposable elements (MITEs) in Xenopus tropicalis (Western clawed frog), we analyzed the intraspecific polymorphisms associated with MITE insertion in X. tropicalis for three subfamilies of the T2 family (T2-A1, T2-C, and T2-E). A high frequency of MITE-insertion polymorphisms was observed at the T2-A1 (50%) and T2-C insertion loci (60%), but none were noted at the T2-E insertion locus (0%). Analyses of the collected data indicated that members of the T2-A1 and T2-C subfamilies may be currently active in the host species. Identification of these active transpositions will help us in understanding the mechanisms underlying the long-term survival (over several tens of millions of years) of the T2-A1 and T2-C subfamilies.
