Research Abstract

We studied the possibility that some transposons whose transposition activities have been retained for a long time in Xenopushave been involved in the evolution of genetic regulatory network. We developed a new strategy to find and classify the T2-MITE transposon family and searched the Xenoousgenomes for T2-MITEs. In addition, we analyzed insertion loci of such transposons and gene expression patterns of neighbor genes and found T2-MITE subfamilies whose transposition and amplification might have driven the evolution of genetic regulatory network of Xenopus.
